Infographic: Astro highlights in winter 2023/24
December 1 2023, Marcus Schenk
The Winter of 2023 gives us some exciting astronomical events that should not be missed. Among these is the Geminid meteor shower that is best to behold under a dark sky, good visibility of a dwarf planet, or interesting interactions between the delicate crescent Moon and the planets. Even cold weather cannot stop us from taking a look at the night sky. One thing we know for sure: It will be fantastic!
This infographic shows you astronomical events for the upcoming months of December, January and February.
You will find accompanying texts below the graphic. Enjoy the observations!
Events in December 2023:
December 9: Moon meets Venus
On December 9 there will be a meeting between the Moon and the bright Venus. This encounter takes place in the early morning hours before sunrise. Both celestial bodies are visible on a horizontal plane. The Moon appears as a thin crescent disk, illuminated only by 14%.
December 14: Geminids
A beautiful astronomical event this month is the Geminid meteor shower. It is a meteor stream that can be seen in the night sky every December. The Geminids are named after the constellation Gemini, from which they appear to come. This year the peak of the meteor shower is expected to be reached in the night of December 13-14, so right in the middle of the month.
December 17: Moon meets Saturn
The thin, but growing Moon meets the planet Saturn on the night of December 17. Compared to its opposition in August 2023, its apparent diameter is much smaller, measuring only 16 arcseconds. Nevertheless, observing it through a telescope is always an impressive experience, especially for beginners. The ringed planet is hard to be missed in its splendor, even though being outside of its best observation period.
December 21: Vesta in opposition
Dwarf planets lead an inconspicious “life”, as they usually stand in the shadow of their larger and more radiant siblings, the planets. Nevertheless, they belong to the extended family of the Solar System. Their observation may not be as spectacular, but on December 21 there is an interesting exception: The dwarf planet Vesta is in opposition and reaches a brightness of 6.4 mag. You can easily find Vesta with binoculars in the Orion region. It is important to use a star chart for this beautiful astronomical event, so that you don’t mistake Vesta for a star.
December 22: Moon meets Jupiter
Tonight the Moon approaches the planet Jupiter and passes by at a distance of only 2.5 degrees. Throughout the night both celestial bodies move away from each other. Therefore, we recommend starting the observation at the beginning of dawn.
Events in January 2024:
January 3: Quadrantids
Not only August offers meteor streams, also January has impressive astronomical events to see. The “Quadrantids” are a meteor shower that appears to come from the constellation of Bootes. In the night of January 3 it reaches its maximum and theoretically you can see up to 120 meteors per hour. However, this is a theoretical value that is significantly smaller in practice. Nevertheless, this astro event is a wonderful experience.
January 5: Moon meets Spica
In January the Winter constellations dominate the sky and shine brightly above our heads. The star Spica reminds us more of Spring, but that is still a while away. Therefore, we have to wait a few more hours, because Spica and the crescent Moon only appear in the middle of the second half of the night above the horizon.
January 9: Moon meets Venus and Mercury
Clear sky and a visible horizon? Then take advantage of the dawn for a quick observation or a mood photo. In the Southeast the two inner planets Mercury and Venus are united with the thin crescent Moon. With or even without any equipment, every stargazer should take advantage of this opportunity.
January 14: Moon meets Saturn
A 3.5-day-old crescent Moon and a clear horizon – always a beautiful sight. But what do we discover nearby? Saturn. The ringed planet is about 3 degrees westward and shines with a brightness comparable to the brightest stars in the sky. How about an observation session of the world of Deep-Sky objects after the Moon has set? The weekend is definitely a good time for that.
January 18: Moon meets Jupiter
The path called the Ecliptic takes the Moon past the planet Jupiter, the brightest celestial body in the current sky, surpassed only by the Moon. Both objects are currently located in Aries. The constellation is rather inconspicious, as it consists of only four rather faint stars.
January 20: Moon meets Pleiades
A few days after the Half-Moon, the Moon meets the Pleiades – the famous Seven Sisters. They have always played an important role in antiquity and in mythology. It is the most prominent open star cluster that we can perceive with the naked eye. It consists of several hundred up to 1000 stars and is located at a distance of about 400 light-years. On photos the Pleiades are surrounded by blueish reflection nebulae, which give them a particularly aesthetic appearance.
January 27: Moon meets Regulus
On January 27 the Moon meets the star Regulus in the constellation of Leo. Regulus is a star with a fast self-rotation of over 300 km/s, which is why it has a flattened shape. Furthermore, it is a multiple system consisting of four components. Due to its position in the Ecliptic, it repeatedly happens that it is occulted by the Moon.
Events in February 2024:
February 1: Moon meets Spica
On the first day of February the Moon meets the star Spica. The star is one of the 20 brightest ones in the entire night sky and shines about 2000 times brighter than our Sun. Unlike our home star, Spica is relatively young – with an age of only 10 million years. Well, that just shows that age is relative.
February 7: Moon meets Venus
Shortly before sunrise we can observe an impressively beautiful constellation that almost takes place in the daytime sky. Early in the morning the Moon and the bright Venus meet. Our neighboring planet is now retreating from the morning sky after having faithfully accompanied us every morning for months. In the coming months it will be in conjunction with the Sun and will not re-appear before the evening sky in September.
February 15: Moon meets Jupiter
In the evening hours Jupiter and the Moon shine above our heads. As they are the brightest objects in the sky, the event immediately catches our attention. Both disappear below the Western horizon around midnight.
February 16: Moon meets Pleiades
On February 16 the Moon joins the Pleiades and crosses the Golden Gate of the Ecliptic on its further path. The Golden Gate is not an object, but an asterism in the sky.
Infographic: Astronomy Highlights of Autumn 2023
August 31 2023, Marcus Schenk
Discover exciting celestial events in autumn 2023. Here are the highlights that are worth observing.
There are some really thrilling celestial events awaiting us in autumn 2023 that we really should not miss. From the best morning visibility of the planet Mercury, to a partial lunar eclipse, to the occultation of gleaming Venus by our Moon. Once again, the next three months have plenty of excitement in store. This infographic shows you all the highlights of the coming months of September, October, and November, and the text below the graphic gives you more details. I wish you lots of observing fun.
SEPTEMBER
01/09 The Aurigids
During the night of 1 September, hobby astronomers can observe a special celestial event in the night sky: the Aurigids. This is an impressive meteor shower that appears to originate from the constellation of Auriga. The Aurigids are known for their bright and fast meteors, which travel at up to 65 kilometres per second. It is worth for us all to get up early or stay awake late, so no one misses this impressive event in the night sky!
04/09 Conjunction of the Moon and Jupiter
We are presented with another highlight on 4 September: the Moon and the gas giant Jupiter meet in the night sky. These two celestial bodies appear above the eastern horizon in the late evening. They climb higher over the course of the night, and will remain until the morning hours, eventually fading in the splendour of the new morning.
05/09 The Moon at the Golden Gate of the Ecliptic
On 5 September the Moon crosses the Golden Gate of the Ecliptic. This phenomenon is a must-see for all celestial observers and offers a wonderful opportunity for observing with the naked eye.
The Golden Gate is neither an object nor a celestial event in itself, but an asterism in the constellation of Taurus. Its luminous pillars are formed by the open clusters Hyades and Pleiades.
The ecliptic, the apparent path of the Sun, runs along this gateway, through which our Moon and the planets appear to pass.
18/09 Venus at its brightest
Venus is at its brightest on 18 September. The evening star shines especially bright with a magnitude of -4.7, and can be seen to the east in the early morning hours. Venus appears almost like a spotlight because it is so bright, and we can still see it in the sky for some time – even as dawn begins to break.
19/09 Neptune at opposition
Neptune is at opposition to the Sun on 19 September, making it visible all night long. Hobby astronomers can observe the gas planet with a telescope, it appears small but intense in colour.
22/09 Mercury visible in the morning
Keep an eye out if you are an early riser! Mercury offers the best morning visibility of the year on 22 September. Back in January, the planet was hard to observe in the morning, but now we have a better chance. Shortly before sunrise, at around 05:50 CEST, the small planet is easily visible in the east, just above the horizon. Mercury is located in the constellation of Leo, so starting from the star Regulus, you can orient yourself around 10 degrees in a north-east direction.
26/09 Conjunction of the Moon and Saturn
The Moon joins the ringed planet Saturn on the evening of 26 September. This meeting offers a picturesque sight, and a highlight for all celestial observers.
OKTOBER
1/10 Conjunction of the Moon and Jupiter
The paths of the Moon and Jupiter intersect once again. On 1 October we can marvel at this impressive event in the evening sky.
9/10 The Draconids
The Draconids shooting stars reach their peak on 9 October. This meteor shower originates from the constellation of Draco, which is located in a northerly direction above the Big Dipper. The number of shooting stars often varies from year to year. So, it is worth keep an eye out for them on different days at different times.
10/10 Conjunction of the Moon and Venus
Four days before the new Moon we can admire Venus and our Moon together in the morning sky. The two celestial bodies shine with a wonderful lustre above and below the star Regulus in Leo. An almost magical sight for every stargazer.
22/10 The Orionids
Meteor showers are lovely events for every avid star-gazer, the Orionids are no exception. They peak on 22 October and promise around 25 to 30 meteors per hour. However, the number of shooting stars often varies from year to year. To catch the best view of them, set your alarm clock and take a look outside in the early hours of the morning. A must for all shooting star fans.
24/10 Golden Handle on the Moon
On 24 October the Moon shows its most beautiful side: the Golden Handle is visible.
The flat light near the lunar terminator creates a breathtaking play of shadows and light. The Golden Handle is especially beautiful. For several hours, the peaks of Monte Jura are illuminated by the rays of the Sun, while the small Sinus Iridum valley is still in the shade. A veritable feast for the eyes that displays the Moon’s beauty in all its splendour.
28/10 Partial lunar eclipse
A special celestial event awaits us on the evening of 28 October: a partial lunar eclipse. The Moon moves into the Earth’s umbra at 21:35 CEST. However, the eclipse magnitude is quite low at only 12.7%. Nevertheless, the eclipse offers a beautiful, unmissable experience in the early evening. So, keep an eye out for this fascinating spectacle in the night sky!
More about the formation of lunar eclipses can be found in our magazine article “How does a lunar eclipse occur?”
NOVEMBER
03/11 Jupiter at opposition
Jupiter is at opposition to the Sun on 3 November. The gas giant is visible all night long and reveals itself in all its glory. This is a special event for all stargazers and hobby astronomers that you should not miss. Of course, you can also observe the gas giant in the coming weeks – not just today. But the planet appears much larger and it shines particularly brightly when it is at opposition. You can see the characteristic dark stripes on Jupiter’s surface with a telescope, along with its four largest moons: Io, Europa, Ganymede, and Callisto.
09/11 The Moon occults Venus
A special event awaits us on the morning of 9 November at 10:55 CEST: an occultation of Venus by the Moon. This is a very rare and impressive spectacle that is definitely not to be missed. It is the astronomical highlight of 2023 for advanced hobby astronomers. In order to observe this occultation, focus your telescope on the illuminated sickle Moon at around 10:50. The Moon will occult Venus from its bright side. The whole spectacle lasts around 80 minutes.
13/11 Uranus at opposition
Uranus is at opposition to the Sun on 13 November. The distant planet is visible all night so it is a great opportunity to observe it with your telescope. Despite its tiny size of 3.8 arcseconds, when you look for it with your telescope you will be able to distinguish it from a star because its surface looks wide and not point-shaped. In addition, its greenish colour is easily recognisable.
17/11 The Leonids
On the night from 16 to 17 November it is once again time – the Leonids reach their annual maximum and ensure a beautiful celestial event. Together with the Perseids, they are among the most well-known shooting stars that can be observed annually from Earth. There are even some years when the meteors fall from the sky in such abundance that it is almost like a rain shower. This spectacle is repeated every 33 years when the Earth comes into contact with the Leonids’ trail. But they will produce up to 20 meteors per hour even in normal years, which is an unmissable experience.
20/11 Conjunction of the Moon and Saturn
The Moon joins the ringed planet Saturn once again on the evening of 20 November. It is a fascinating sight that will accompany us in the evening sky.
25/11 Conjunction of the Moon and Jupiter
At the end of the month, on 25 November, we have another chance to marvel at an encounter between the Moon and Jupiter in the night sky.
Infographic: Astronomy Highlights of Summer 2023
May 31 2023, Marcus Schenk
Observing in summer! This means warm temperatures, but also some interesting constellations and the visible part of the Milky Way. In this infographic you will find all the important astronomical events in the summer of 2023 that you really should not miss. How about Saturn at opposition, or the Perseids shooting stars which we can enjoy this year without any interference by the Moon?
Whether you are an experienced amateur astronomer or a complete beginner to the field of astronomy: the astronomy events in our infographic offer something for everyone.
We wish you lots of observing fun!
02/06 Mars near M44
There is an interesting encounter in the evening sky at the moment: Mars, the Red Planet, can be found close to the M44 cluster, and the pair offers a beautiful view. The constellation is easy to see, especially at dusk close to the western horizon. But it is not only Mars that is attracting attention: at a distance of around 10 degrees, Venus is also close by.
09/06 Conjunction between the Moon and Saturn
A very special performance is awaiting us in the sky this morning: the Moon and Saturn meet in the constellation of Aquarius and provide us with an impressive sight. Jupiter can also be seen nearby which rounds off the spectacle perfectly.
13/06 Venus near M44
On 13 June, Venus will be in close proximity to the open cluster M44, which is also known as the Beehive Cluster. It’s great when you can combine such an astronomical event with some deep sky observation.
14/06 Conjunction between the Moon and Jupiter
On 14 June, just four days after its meeting with Saturn, the Moon will be spending some time with the planet Jupiter. This beautiful dawn sight is worth getting up early for, because the Moon appears as a delicate sickle and will soon reach its new Moon phase.
21.06 Beginning of summer
Summer begins with the summer solstice on 21 June. In the northern hemisphere this means that the Sun reaches its highest point in the sky. We cannot actually observe this astronomical event, but we are now experiencing the longest days and the shortest nights.
21/ 22.06 Conjunction between Venus and Mars
21 June is a day that you should be certain to make a note of in advance. This evening, above the western horizon, Venus and Mars meet up with the narrow crescent Moon. This trio is especially impressive when it is not yet completely dark, and we can also enjoy the twilight sky.
27.06 June Bootids
From 23 to 28 June you can observe the June Bootids meteor shower. These shooting stars radiate from a point in the constellation of Boötes and fizzle comparatively slowly across the sky. The number of meteors is small but also variable. This means that it is particularly interesting to take a closer look.
01.07 Conjunction between Venus and Mars
Our two neighbouring planets, Venus and Mars, meet on 1 July. These two celestial bodies differ greatly in brightness, which makes them especially interesting to observe. You should not miss this opportunity if you are a big Mars fan, because the Red Planet will disappear from the celestial stage this month, and remain invisible for the rest of the year.
07.07 Conjunction between the Moon and Saturn
The Moon and Saturn rise above the horizon at the beginning of the second half of the night, and accompany us through till sunrise. Both celestial bodies can be found in the constellation of Aquarius.
09.07 Venus at its brightest
Venus reaches its maximum brightness on 9 July, and looks almost like a spotlight in the sky – an impressive spectacle for amateur astronomers.
12.07 Conjunction between the Moon and Jupiter
Jupiter rises on 12 July at 01:23, and reveals itself beside a slim, waning crescent Moon.
20.07 Conjunction between the Moon, Venus, and Mars
Another fascinating event awaits us in the night sky on 20 July. The wafer-thin crescent Moon approaches Venus and, together with Mars, forms an attractive group of three. However, you will need an uninterrupted view towards the horizon to successfully observe this. If you want to enjoy this sight or even take pictures, you should find a good spot as early as possible. A tip for the professionals: the planet Mercury is also located around 10 degrees west of Venus.
22.07 Pluto at opposition
An astronomical event for more advanced astronomers: Pluto, the dwarf planet former classified as a planet, is at opposition to the Sun on 22 July. With a brightness of magnitude 14, you can only detect and observe it with a large telescope. A location map is advisable! Astrophotographers can take advantage of a good photo opportunity since Pluto is close the M75 cluster.
27.07 Golden Handle
We can see the Golden Handle on the Moon on the evening of 27 July. It appears when the waxing Moon is exactly 83 percent illuminated, which happens around 10 days after the new Moon. As the light phenomenon takes place, a handle shape emerges on the dark side of the Moon’s terminator.
30.07 Delta Aquariids
The Delta Aquariids is a meteor shower that originates from the region of the constellation Aquarius, and is visible from 23 to 28 July. We will be able to marvel at up to 25 shooting stars per hour! The optimal observing window is in the early hours of the morning, after the Moon has set.
03.08 Conjunction between the Moon and Saturn
An interesting encounter: the Moon nears the planet Saturn. The ringed planet will reach its opposition to the Sun this month and is therefore an especially good target to observe.
08.08 Conjunction between the Moon and Jupiter
In the early morning hours, we can enjoy the autumn and the first winter constellations in the night sky. Our largest planet, Jupiter, is to be found right in the middle of them. On the 8th of the month, the Moon approaches the gas giant and they make an arresting pair in the night sky.
12-13.08 Perseids
A view of the Perseids is the top astronomy event not just for astronomers, but also for anyone who is interested in the night sky. An especially large number of meteors fall from the sky over the course of an evening, and everyone can enjoy guessing which direction the next light trail will appear from. It’s finally time to see them again during the night from 12 to 13 August. Grab a blanket or a lounger and something warm to drink, and enjoy the starry sky. If you’re lucky, you’ll see up to 100 meteors per hour this evening. This year there is an added plus: it is almost new Moon, so the night is particularly dark.
27.08 Saturn at opposition
The ringed planet Saturn is at opposition to the Sun on 27 August and can be observed all night long – an absolute highlight for any amateur astronomer.
30.08 Conjunction between the Moon and Saturn
In the night from 30 to 31 of the month, the Moon and Saturn meet at a distance of around 3 degrees. Despite the full Moon, it is always worth observing Saturn.
Infographic: Astronomy Highlights in Spring 2023
March 1 2023, Marcus Schenk
Spring is a great time to take a look at the stars: it’s getting warmer, and the weather in Central Europe is better. And, as always, there are plenty of interesting celestial events to see: a minor planet at opposition, the only time the planet Mercury is visible in the evening, and some beautiful conjunctions between planets and the Moon. In this infographic you’ll learn about the top astronomical events in the night sky during the spring of 2023. There’s no better reason to get outdoors again with your binoculars or telescope.
Events in March
01/03 Conjunction between Venus and Jupiter
On 1 March, you can observe a very special astronomical event: at dusk, Venus and Jupiter draw closer to one another, until they are around a half a degree apart. This is approximately the same distance as the diameter of a full Moon. The encounter is a rare opportunity to marvel at these two bright celestial bodies in the evening sky.
10/3 Ceres near M91
Today Ceres intersects the bright spiral galaxy known as M91, thereby offering us the rare opportunity to admire both the minor planet and the galaxy simultaneously with our telescope. Ceres is the largest object in the asteroid belt between Mars and Jupiter.
The planet has a diameter of around 950km which is about the length of Spain. Ceres was considered to be a planet following its discovery in around 1801, and it was only later re-defined as a minor planet. Ceres thus faced a very similar fate in its classification as Pluto did in 2006.
A closer inspection by the Dawn Spacecraft discovered many craters, most of which are only small. Water vapour was even discovered there in 2015, and further research suggested that there may be liquid water under the surface. So, we can say with certainty: it’s a very interesting celestial body! Use your telescope to enjoy the rare sight of Ceres and M91 together!
14/03 Conjunction between the Moon and Antares
Today is a good day for early risers: the Moon nears Antares, the brightest star in the constellation of Scorpio, at a distance of just 1.5 degrees. You can only observe and enjoy the meeting of these two in the morning hours. So, maybe on your way to work?
21/03 Ceres at opposition
Have you ever observed a minor planet? Ceres, which was discovered in 1801, is the largest object in the asteroid belt. It’s at opposition now, and its brightness reaches a magnitude of 7. You can locate it with small telescopes and, theoretically, even with binoculars. Have fun!
24/03 Conjunction between the Moon and Venus
The delicate sickle Moon rises above the western horizon, serving as the perfect complement to gleaming Venus. With a brightness of magnitude 4, Venus is a wonderful sight at dusk and will entice you outside to look at the stars tonight. Less than 3 degrees separate these two celestial bodies, which guarantees a particularly beautiful sight. It’s always an impressive natural wonder when the Moon meets Venus, especially if you’re planning to capture it with your camera.
25/03 Conjunction between Ceres and M100
Make a note of date: the minor planet Ceres crosses another deep sky object! Its path takes it past the breath-taking galaxy M100 in the constellation of Coma Berenices. Using a finderscope, you can locate it above Denebola, the star that marks the tail of the constellation of Leo.
28/03 Conjunction between the Moon and Mars
Tonight, the Moon and the planet Mars can be found very close together. Observing these two celestial bodies framed by the stars of the Winter Hexagon is a truly impressive sight.
Events in April
03/04 Mercury in the evening sky
Mercury is a nimble planet as its orbit is located close the Sun. This usually makes it difficult to observe, because it only rarely escapes the brightness of our central star. The only evening visibility this year occurs in April: Mercury reveals itself a few degrees above the western horizon between 3 and 15 April.
10/04 Conjunction between the Moon and Antares
Tonight, the Moon is in the constellation of Scorpio and nears the bright supergiant star Antares. This occasion takes place in the morning hours. But a further event awaits us: the occultation of the magnitude 3 star by our Moon. At 04:52, the bright side of our satellite moves towards the star and occults it for around an hour. We will not be able to see the star’s reappearance on the other side of the Moon, as, by this time, it will already be daylight.
16/04 Conjunction between the Moon and Saturn
Keep an eye out if you’re an early riser: this morning we are greeted by the waning crescent Moon and the planet Saturn above the eastern horizon. You’ll need to choose a place with a good view of the horizon to observe this.
22/04 Conjunction between the Moon and Venus
Tonight, we can observe a really special spectacle: a conjunction between the Moon and Venus. The Moon is just 2.5 days old, so we only see a slender sickle form. Venus, on the other hand, shines brightly at more than magnitude 4, so it appears especially bright in the evening sky.
22/04 The Lyrids
On 22 April, at its maximum, the Lyrid meteor shower produces up to 20 meteors per hour. The meteors can be observed undisturbed by moonlight during the best observation time which is between 22:00 and 04:00 next morning. Their point of origin, also known as the radiant, is located in the constellation of Lyra.
25/04 Conjunction between the Moon and Mars
Today, the Moon and Mars can be seen in the constellation of Gemini. This is a rare sight not to be missed.
Events in May
13/05 Conjunction between the Moon and Saturn
This morning the Moon nears the planet Saturn. Such a lovely sight is certain to get us motivated for the day ahead.
23/05 Conjunction between the Moon and Venus
Venus – almost as bright as a spotlight in the night sky – together with the slender crescent Moon. This is exactly what you will see if you look up at the sky this evening. What’s more: a little higher you’ll find Mars too. When compared to its two colleagues, it seems to be really dimly lit.
24/05 Conjunction between the Moon and Mars
Whereas the Moon visited Venus yesterday, today it is calling on the planet Mars.
26/05 Conjunction between the Moon and Regulus
If you have been observing the Moon in recent days, you will have noticed how quickly it moves against the background of stars. Today it meets Regulus, the brightest star in the constellation of Leo. The name Regulus comes from Latin and means ‘little king’.
31/05 Conjunction between the Moon and Spica
Today, the Moon meets the brightest star in the constellation of Virgo: Spica. We owe this coincidence to the path of the ecliptic, which repeatedly leads the Moon into the vicinity of this star. The best observation time starts in the late twilight, because Virgo will disappear below the horizon in the second half of the night.
Astronomy Highlights in Winter 2022/2023
November 30 2022, Marcus Schenk
Mars at opposition, two planetary occultations by the Moon, the Geminids and beautiful triangular arrangements between the Moon and the planets. This winter, there are many reasons to look towards the stars. And you should join in!
In the “Astronomy Highlights in Winter 2022/23” infographic, you can find important celestial events for the next three months. Have fun observing!
December
02/12 Conjunction between the Moon and Jupiter
When darkness is upon us, we can gaze at the Moon and Jupiter on the south-eastern horizon. The gas giant will be blazing with an intensity of -2.5 magnitudes.
05/12 The Moon occults Uranus
The Moon and the planets travel along an imaginary line known as the ecliptic. This is the plane along which the planets and the Sun appear to move. Every now and then, the Moon occults one of the planets. And that time has come once again, as the dark side of the Moon approaches and occults Uranus at 5:34pm.
07/12 Conjunction between the Moon and Plejades
In the early hours of 7 December, the almost-full moon reaches the Golden Gate of the Ecliptic, which is flanked by the famous Hyades and Pleiades star clusters.
08/12 The Moon occults Mars/Opposition
Mars is at opposition to the Sun today and is shining particularly bright and looks magnificent through a telescope. During this year’s opposition, the planet reaches a diameter of 17 arc seconds and a height of 66 degrees above the horizon from central Europe. And today is also a double event as, in the early hours of 8 December, at around 6am, our Moon occults the Red Planet.
14/12 Geminids
If the skies are clear in the evening, look towards the south. You will see the Geminids meteors emerging from the constellation of Gemini. Or more precisely, from a spot two degrees above the star, Pollux. With 120 meteors per hour, this shower is one of the events with the highest fall rates. In the early evening, up to 10pm, you can view it undisturbed by the Moon, as this is when our satellite appears over the horizon.
Lunar phases:
08/12 Full moon, 16/12 Waning quarter, 23/12 New moon, 30/12 Waxing quarter
January
01/01 Conjunction between the Moon and Uranus
Over and over, encounters or occultation between the Moon and planets take place along the path of the ecliptic. At the start of the new year, the Moon scrapes past Uranus at a distance of only half a degree.
03/01 Conjunction between Moon and Mars
Two bodies are competing for brightness today… the Moon and Mars. Both appear in the eastern skies when darkness falls. The Moon passes eastward beneath Mars.
03/01 Quadrantids
The next meteors are on their way to us – the Quadrantids. This meteor shower originates in the constellation of Bootes. The meteors shoot across the sky at a maximum rate of 120 per hour. The Moon only leaves our field of vision in the early hours of the morning.
16/01 Pallas at opposition
With a diameter of 588 kilometres, the asteroid Pallas is the second largest in the asteroid belt between Mars and Jupiter. During its opposition, it is so bright that we can easily see it with a small telescope and, theoretically, even with binoculars. To tell it apart from the stars, you should use a star chart whilst observing.
22/01 Conjunction between Saturn and Venus
A good view of the horizon is essential for this event. During twilight, the stunningly bright Venus outshines the considerably weaker, but still bright, Saturn above the western horizon. From 5:30pm, we have an hour-long opportunity to follow this celestial pair, both of which become weaker and then disappear into the haze.
23/01 The Moon near Venus and Saturn
An attractive event for all who are interested… Today a slim crescent moon joins the planets Venus and Saturn. Together, they are a dream team for a wonderful twilight photo.
30/01 Conjunction between the Moon and Mars
This evening, the Moon visits the Red Planet. During the night, our satellite draws nearer until both objects are around one degree apart in the morning hours.
Lunar phases:
07/01 Full moon, 15/01 Waning quarter, 21/01 New moon, 28/01 Waxing quarter
February
15/02 Conjunction between Venus and Neptune
Venus and Neptune come to within 0.25 degrees of each other – a very close encounter between two very different planets. Whilst Venus beams like a floodlight, Neptune shines 50,000 times less bright.
22/02 Conjunction between Venus and Jupiter
This evening, the crescent moon appears with two planets. A beautiful view which you should not miss.
27/02 Conjunction between the Moon and Mars
This evening, Mars and the Moon can both be found in the constellation Taurus.

Astronomy highlights in Autumn 2022
August 31 2022, Marcus Schenk
Autumn is on its way, and the evenings get dark earlier. For many, this marks the start of a great observing season. And it’s all there: Saturn is eye-catching as it shines in the night sky, Jupiter is at opposition and there will even be a partial eclipse of the Sun! What’s more, the Moon will occult Uranus. And that’s just the start!
In our “Astronomy Highlights in Autumn 2022” infographic, you’ll find many of the important celestial events at a glance. Information and further explanations of the events can be found in the accompanying text.
Have fun observing!
September
11/09 Conjunction between the Moon and Jupiter
The Moon and Jupiter rise almost together and we can admire them at around 9 p.m. above the eastern horizon.
14/09 The Moon occults Uranus
The Moon and the planets move along an imaginary line in the sky known as the ecliptic. This refers to the apparent path along which planets move around the Sun. Once in a while the Moon occults one of the planets. Now, on the 14th, it’s that time again: the Moon approaches with its illuminated side and occults Uranus at around 10 p.m.
16/09 Conjunction between the Moon and Mars
Shortly before midnight, the constellation Taurus climbs above the eastern horizon and will look particularly attractive today, because it also marks the meeting place of Mars and the Moon. Together with Aldebaran, Capella and the Pleiades, it makes a lovely sight.
16/09 Neptune at opposition
Our farthest planet is at opposition to the Sun tonight. Neptune is currently 4.3 billion kilometres away from us and shines with a magnitude of 7.8. Its light takes 4 hours to reach the Earth. We can even see Neptune with binoculars, though it cannot be distinguished from a star. It is only with a telescope that can we identify it as a planet with certainty. But it’s not so easy to find as Jupiter or Saturn. A star chart or app will help you.
26/09 Jupiter at opposition
An opposition is quite special: for this is when a planet is directly opposite the Sun and shines brightly all night long. Jupiter is currently at an altitude of 42 degrees above the horizon. This is considerably higher than in recent years, which greatly improves the quality of our observations.
Lunar phases:
03/09 First Quarter, 10/09 Full Moon, 17/09 Last Quarter, 25/09 New Moon
October
05/10 Conjunction between the Moon and Saturn
Tonight, the Moon passes below the ringed planet. On the Moon you can also observe the phenomenon known as the Golden Handle, an illuminated mountain at the Moon’s terminator.
08/10 Conjunction between the Moon and Jupiter
Time for a planetary evening! The Moon and Jupiter meet today in the constellation Capricorn. In September, Jupiter was at opposition to the Sun and is still an excellent object for any telescope. Tonight, we won’t be disturbed by a bright Moon.
11/10 Mercury in the morning
From 5 October, we can catch Mercury in the morning sky. The closest planet to the Sun is usually too close to it, which is why we rarely see it. October is the only time this year that it is visible in the night sky.
14/10 Conjunction between the Moon and Mars
From midnight, we get a taste of winter because then the constellations Auriga and Taurus appear above the horizon. In the middle of all this we can also see Mars and the Moon, which are particularly close to one another today. Can you see the red colour of our neighbouring planet?
21/10 Orionids
The Orionids are a small meteor shower producing around 20 meteors per hour. The radiant is located in the constellation Orion near the star Betelgeuse. Although you can observe the shooting stars throughout the month, they will be at their peak between 20 and 21 October. The best time to observe them is between 10 p.m. and 4 a.m.
24/10 Conjunction between the Moon and Mercury
Are you an early riser? Perfect, because this morning you can take a quick look at the slender crescent Moon and Mercury. For this you will need an elevated location or an unobstructed view towards the horizon. Then, just before sunrise from 6:50 a.m., you will discover the two celestial bodies.
25/10 Partial solar eclipse
The last partial eclipse that was visible to us was on 10 June 2021. A little more than a year later we can follow the next one. It starts at around 11a.m. on 25 October when the Moon moves in front of the Sun and obscures around 25% of it.
Important: use a solar filter when observing. Safe filters are available in our Astroshop.
Lunar phases: 09/10 Full Moon, 17/10 Last Quarter, 25/10 New Moon
November
01/11 Conjunction between the Moon and Saturn
The waxing crescent Moon and the planet Saturn are now to be found together in the constellation Capricorn.
04/11 Conjunction between the Moon and Jupiter
This evening, the waxing Moon meets the planet Jupiter, which was at opposition in September. Over the course of the night, the two celestial bodies approach at a distance of around 2 degrees.
09/11 Uranus at opposition
Uranus is one of the most distant gas giants. It appears only as a tiny, greenish disc in a telescope and we cannot make out any detail. However, you can still distinguish it as a planet. Find Uranus with a star chart or, easier still, with your telescope’s GoTo system. Then you can identify the planet using 150 to 200 times magnification.
11/11 Conjunction between the Moon and Mars
Tonight, the waning Moon finds itself close to the planet Mars. The Red Planet is between the Moon and Aldebaran, the brightest star in the constellation Taurus. An interesting task for today is to compare the intensity of the red colours of Mars, Aldebaran and Betelgeuse.
17/11 Leonids
From 16 to 17/11, the Leonids reach their peak. Together with the Perseids, they are among the most famous meteor showers. In some years these meteors fall like raindrops from the sky. This usually happens every 33 years when the Earth meets the Leonids’ debris cloud. In normal years, the peak does not exceed 20 meteors per hour. This year, you can observe them during the first half of the night, undisturbed by moonlight.

September 1 2021, Marcus Schenk
Autumn has a planetary focus on Jupiter and Saturn which are both still brilliantly visible. Additionally, you have the chance to see the two outermost planets, Uranus and Neptune, at opposition.
In the “Astronomy Highlights in Autumn 2021” infographic, you can find numerous important celestial events at a glance. You can find dates and detailed descriptions of the events in the accompanying text.
Have fun observing!
September
September occurs in the period between summer and autumn. This can also be seen in the night skies. The constellations Hercules and Lyra drift westward. Contrastingly, the constellation Capricorn is conspicuous alongside the large planets Jupiter and Saturn in the south.
02/09 The Moon occults Epsilon Gem – In the early hours of the morning, the slender crescent moon occults the star Epsilon Gem in the constellation Gemini. The Moon approaches with its illuminated side at around 2am. You need a very good view of the horizon facing towards the north-east. (Visibility depends on observer location)
03/09 The Moon occults Epsilon Gem – At 4:38am, the slender crescent moon occults the star Kappa Gem in the constellation Gemini. An attractive occultation as the Moon appears as a narrow crescent. (Visibility depends on observer location)
3.9. Conjunction between the Moon and Pollux – In the second half of the night, the Moon appears over the horizon in the constellation Gemini. Only 3 degrees separate it from Pollux.
14.9. Neptune at opposition – The solar system’s furthest planet is at opposition and looks magnificent. You can see it as a star by using binoculars but it is only by using a telescope that you can see the 2.3 arc second planet as a small sliver. A star chart or an app would benefit you here.
17.9. Conjunction between Jupiter and Saturn – Both large planets meet in the constellation Capricorn. With the Moon in the middle, they form a triangle.
October
October definitively marks the start of autumn. High above our heads we can see the famous Great Square of Pegasus and the constellation Andromeda. Time to take an extensive trip to the Andromeda Galaxy. Always an experience with binoculars.
03/10 The Moon occults Eta Leo – In the early hours of the morning, at around 5:27am, it is still dark. It is now that the Moon occults the 3.4 mag star Eta Leo with its narrow-illuminated side. It is definitely the most impressive star occultation of the quarter. (Visibility depends on observer location)
08/10 Giacobinids – The Giacobinids or Draconids are a meteor shower which appears to stem from the constellation Draco. The maximum fall rates can be expected on 8 October. Unfortunately, the expected number cannot be predicted as it can vary considerably. The radiant is located near the star Beta Draconis. Draco is part of a circumpolar constellation which is why the radiant is at its optimal visible altitude in the evening.
09/10 Conjunction between the Moon and Venus – At sunset, a brilliant Venus and a 3.5-day-young crescent moon rise in the southwest. There is a maximum time window of 2 hours until Venus disappears below the horizon.
14-15/10 Conjunction between the Moon, Jupiter and Saturn – At the end of the civil twilight, at around 19:00, the planets Jupiter and Saturn rise dominantly in the sky. Although they were at opposition in August, they are still a rewarding target. The Moon does not disrupt their observation.
21/10 Orionids – The Orionids are a smaller meteor shower with around 20 meteors per hour. The radiant is located in the constellation Orion, near the star Betelgeuse. Although you can observe the meteor shower all month, it peaks between October 20 and 21. The best time for observing is between 22:00 and 05:00.
23/10 Mercury in the morning sky – In May, Mercury could be seen in the evening sky whereas now the planet is offering us a short period of morning visibility. Between 23/10 and 31/10, you can see it just above the eastern horizon.
November
The constellation Perseus is near the zenith in November. This is where you will find the two brightest stars, Mirfak and Algol. The famous binary star cluster h + chi illuminates the space between Perseus and Cassiopeia and can be seen with the naked eye in dark areas.
03/11 Conjunction between the Moon and Mercury – There are two reasons to get up early today. This morning, the delicate crescent moon and Mercury are in conjunction. One of the last opportunities before Mercury disappears into the Sun’s glare.
05/11 Uranus at opposition – At mag. 5.6, Uranus is currently visible with the naked eye. However, it is easier to spot using binoculars or a telescope. This makes it appear as a tiny green disc with no recognisable details. However, it can still be identified as a planet.
08/11 Conjunction between the Moon and Venus – The waxing crescent moon is in conjunction with the twinkling brightness of Venus.
10/11 Conjunction between the Moon and Saturn – The Moon passes Saturn only 4.5 degrees beneath it.
11/11 Conjunction between the Moon and Jupiter – Tonight the Moon passes Jupiter, moving at almost one degree per hour. We can track the movement relative to Jupiter quite well.
17/11 Leonids – The Leonids reach their peak from November 16 to 17. Along with the Perseids, they are one of the most famous meteor showers. There have been years in which these meteors have fallen like raindrops from the sky. This generally takes place every 33 years when the Earth runs into the Leonid cloud. In normal years, the shower does not exceed 20 meteors per hour at its peak. This year, the slender crescent moon sets early on and we can enjoy the meteors all night long without interruption.
Infographic: Astronomy Highlights in Spring 2021
February 26 2021, Marcus Schenk
A visit to the Pleiades, a very bright minor planet and a superbly-visible Mercury in the evening sky. There’s lots to look forward to the astronomical spring, because it has plenty to offer.
In the infographic Astronomy Highlights in Spring 2021, you have an overview of the important celestial events for the next three months.
We wish you lots of observing pleasure!
March
4/3 Mars near the Pleiades (Golden Gate of the Ecliptic)
Mars was in opposition last year and was visible in the starry evening sky. It still gleams in the night sky, disappearing ever more from the picture, along with the winter constellations. Around 4 March it nears the Pleiades at a distance of about 2 degrees. In doing so, the god of war also passes through the Golden Gate of the Ecliptic. This is the name of the area between the Hyades and the Pleiades, through which the ecliptic takes its course.
4/3 Vesta at opposition
Vesta is a goddess in Roman mythology but also the name of a well-known minor planet. With a diameter of 520 kilometres, it is the second largest in the asteroid belt. While at opposition, it can sometimes be distinguished with the naked eye. Currently, at mag. 5.8 – 6.0, it is just beyond the visibility of the naked eye. However, it is easy to see with binoculars or a telescope. So how about observing a minor planet? That would make a very special star-gazing evening. What’s more, you can easily find Vesta in the rear part of the constellation Leo. From star Theta Leonis (the hind leg of the lion), just one degree to the northeast – et voilà.
5/3 Mercury near Jupiter
A difficult encounter: Mercury and Jupiter are near one another, but they are not easy to track. When both become visible, it will be shortly before 6:00am and the Sun will be just 8 degrees below the horizon. The time window is short and you need a clear view of the horizon as the two planets approach with a separation of just 0.3 degrees.
10/3 the Moon nears Jupiter and Saturn
Just before dawn for early risers: several objects gather together over the south-eastern horizon this morning. Almost as if they were on a diagonal pearl necklace, you will discover Mercury, Jupiter and Saturn. The delicate crescent Moon frames this meeting of the planets, and turns the morning into a wonderful astronomical event.
16/3 the Moon nears Uranus
In the evening hours we see the waxing crescent Moon between the constellations Cetus and Pisces. If you like, you can make a detour from here with your telescope, to the distant planet Uranus. Because today it is just 6 degrees above the Earth’s satellite. Uranus is always worth a look, because it is not a standard object, such as Saturn or Jupiter. As a distant planet, even in a telescope it is just a small disc which, if you look closely, is clearly different from a star. Nevertheless, it makes sense to familiarise yourself with the exact position on a star chart before observing.
18/3 Mars nears u Tauri
A few days ago, Mars moved through the Golden Gate of the Ecliptic, past the Pleiades. Today it stops at u Tauri in the constellation of Taurus, at a star that is a member of the Hyades. This is a pulsating star, which changes its luminosity within a few days. If you scan through this area with binoculars, you will notice a pattern made up of many stars. This is an asterism, a pattern-like group of stars. It’s called Davis’ Dog and depicts a dog with a nose, eyes, ears, legs and tail. Although some people see it as a fox. What do you see?
April
1/4 Antares nears the Moon
During the night from 1 – 2 April, the Moon approaches the brightest star in Scorpius: Antares. It is a red supergiant and shines brightly and red-hued in the night sky. Its diameter is 700 times greater than that of our Sun and it would swallow some planets, including our Earth, if it were to take the place of our own celestial body.
6/4 the Moon nears Saturn
The morning sky already shows us the heralds of summer: the constellations Sagittarius and especially Capricornus. In the realm of this mountain goat, the Moon and Saturn meet today and stand at a separation of 5.3 degrees.
15/4 the Moon passes the Golden Gate of the Ecliptic
Three days after the new Moon, the delicate crescent Moon appears again in the evening above the western horizon. Our satellite reaches the Golden Gate of the Ecliptic, which is flanked by the famous star clusters of the Hyades and the Pleiades.
17/4 the Moon nears Mars
The Moon and Mars meet tonight at a distance of around 2.5 degrees. The Red Planet is still in the constellation Taurus, but on 24 April it will move to the constellation Gemini.
19/4 the Moon nears Pollux
The Moon approaches the star Pollux in Gemini at a separation of 3.3 degrees. The more interesting thing tonight, however, is the occultation of star kappa Gem by the Moon. It approaches with its unlit side and swallows the bright mag. 3.5 star for a little more than an hour. The occultation can only be followed in certain regions with sufficient darkness. In Germany, the occultation begins at around 20:21.
26/4 Venus nears Mercury
This is something for specialists: because Venus and Mercury are not yet visible in the evening sky. But at dusk, the two inner planets approach one another and pass by at a distance of 1.3 degrees. At 20:45 CEST, the Sun will be just 4 degrees below the horizon and the planets will be slightly above it. So you may catch a glimpse with large binoculars, but it’ll be difficult to observe.
May
4/5 the Moon nears Saturn
Capricornus belongs to the summer constellations and is already climbing above the horizon in the morning sky. The planet Saturn will remain in this constellation for the next two years, before it moves to Aquarius. However, this morning the Lord of the Rings gets a visit from the Moon.
5/5 the Moon nears Jupiter
Yesterday, the Moon visited Saturn, today it also calls on Jupiter. It is still in the neighbourhood, after Jupiter and Saturn met in a very close conjunction last December.
10/5 Mercury visible, evening sky
Mercury has good evening visibility this month – it’s the only month this year when it is really easy to observe. From 10 May, it’s easy to find on the western horizon. At around 21:30 it will be dark enough that you will have no problem seeing it gleaming in the sky. Venus is on the verge of setting, but Mercury is around 8.5 degrees above the horizon. This means: if you have a good view towards the horizon, you have an hour until it disappears in the haze of the horizon and sets. Over the course of the month the little planet climbs the stairway to the heavens, and will be located a little higher every day. On 18 May, it will not set until 22:53 CEST – but thereafter it sets a little earlier every day.
13/5 the Moon nears Mercury
One of the most beautiful encounters on the evening sky: shortly after sunset today, the 3.5% illuminated crescent Moon joins Mercury and will be just 2 degrees to the south. Further below you will discover Venus.
15/5 the Moon nears Mars
In the far west, today the still-narrow crescent Moon meets with Mars in the constellation Gemini. By the way, NASA launched a new robot mission to Mars last year. NASA successfully landed the Perseverance rover on Mars in February, as part of the Mars 2020 mission. The first ever Mars helicopter is on board. Controlled by rotor blades, the drone will fly through the thin “air” and help to explore Mars from a low altitude.
17/5 Mercury at greatest eastern elongation
Mercury is at its largest eastern elongation today. With this, it reaches its greatest angular distance from the Sun and holds an easy-to-observe position above the horizon. We now have more than an hour to marvel at it before it sets. If you want to observe it with a telescope, now is also the right time – as the planet sneaks away from the thicker layers of air in the atmosphere.
17/5 the Moon nears the Beehive
It is often simply called M44 or Praesepe, but a particularly nice name for this object is: the Beehive cluster. Like in a luminous beehive, there are about 300 stars bustling in this open star cluster. The Moon nears the Beehive at about 4 degrees. This means you can see both objects with a pair of binoculars in the same field of view.
19/5 the Moon nears Regulus
Tonight, the waxing Moon nears Regulus, the main star in constellation Leo, which is also called Little King in German. Its position is close to the ecliptic, which means that repeated occultations of Regulus by the Moon can occur.
28/5 Mercury near Venus
Mercury had its best evening visibility this month and was positioned high above the horizon. Meanwhile, it has lost some height and is joining up with lower-positioned Venus. They pass by one another, but meet on the 28th and approach each other at a separation of up to 0.5 degrees.
31/5 the Moon nears Saturn
In the second half of the night, you can observe the Moon and Saturn in a southerly direction in constellation Capricorn. The constellation climbs higher and higher until daybreak, and approaches the meridian, the highest point in the sky.
Astronomy Highlights in Autumn 2020
August 28 2020, Marcus Schenk
Mars at opposition, Moon-less Leonids and an interesting star occultation in the evening. Once again, there are plenty of reasons to look to the stars.
Don’t let anything pass you by in the next three months: In the ‘Astronomy Highlights in Autumn 2020’ infographic, you will find a quick overview of numerous important celestial events. In the accompanying text you will find further useful details.
We wish you many exciting hours of viewing.
September:
06/09 Conjunction between the Moon and Mars
On the evening of the 5th, the Moon and Mars are in close alignment and both appear above the eastern horizon from 21:30 CEST. They draw ever closer throughout the night, until the early hours of 06/09 when they are less than one degree apart.
11/09 Neptune at opposition
Neptune is the solar system’s outermost planet. Many observers have only caught glimpses of it to date. But now it has reached its opposition and will spend the whole night in a favourable position in the sky. We can find it above the eastern horizon, between Aquarius and Pisces, during the evening. At mag 7.8, it can be found using any pair of binoculars, but 4.3-billion-kilometre-away Neptune’s planetary disc can only be seen through a telescope.
14/09 Conjunction between the Moon, Venus and M44
Are you an early riser? Excellent. Then you will be able to enjoy an encounter between the Moon, Venus and the open star cluster, M44. It can be seen by the naked eye in dark skies. All three celestial objects are in an almost straight line, with M44 at its centre. What makes this particularly attractive is that the Moon is waning and only 14% illuminated.
25/09 Conjunction between the Moon, Jupiter and Saturn
Throughout the summer, we have been able to observe Saturn and Jupiter in Sagittarius in the evenings. It was the highlight of every astronomical observation. Shortly after the start of autumn, on 25/09, an attractive view of them presents itself with the Moon.
October:
03/10 Conjunction between the Moon and Mars
This month, the Moon has also noticed that Mars is the star of the month. After all, there are two conjunctions between them in October. Tonight they are separated by a distance of 4 degrees.
03/10 Conjunction between Venus and Regulus
Just before dawn, we see the spring constellation Leo appearing in the east. Venus and the main star, Regulus, are strikingly close together – the latter of which ranks as the 22nd brightest star in the night sky. It is fun to compare the large difference in magnitudes between the two celestial bodies at the same time.
08/10 Giacobinids
The Giacobinids or Draconids are a meteor shower which appears to stem from the constellation Draco. The maximum rates can be expected on 8 October. Unfortunately the expected number cannot be predicted as it can vary considerably.
The radiant is located near the star Beta Draconis. Draco is part of a circumpolar constellation which is why the radiant is at its optimal visible altitude in the evening.
14/10 Mars at opposition
Mars orbits the Sun once every 686 days, reaching opposition approximately once every two years. The last opposition, in 2018, gave us a perigee and a supersized Mars, but it was low above the horizon. This year, its disc diameter is only two arc seconds smaller but it is located considerably higher in the sky. This results in one of the best opportunities for observation in the coming years.
21/10 Orionids
The Orionids are a smaller meteor shower with around 20 meteors per hour. The radiant is located in the constellation of Orion, near the Betelgeuse star. Although you can observe the meteor shower all month, it peaks between October 20 and 21. The best time for observations is between 22:00 and 05:00.
21/10 The Moon occults Gamma Sgr
Lunar occultations are fascinating for every observer, especially when they start on the dark side of the Moon. The evening of 21 October provides an ideal example of this. The bright mag 2.8 star, Gamma Sgr, is occulted in the constellation Sagittarius at 20:35. With bright stars like this, the effect is amazing. It disappears behind the Moon as if it has been switched off and only reappears at 21:42 on the far side. In many places, the Moon may have already set by then.
22/10 Conjunction between the Moon, Jupiter and Saturn
Barely one month after the last conjunction, the Moon once again joins the planets Jupiter and Saturn. The best observation time is at dusk.
29/10 Conjunction between the Moon and Mars
This evening, the Moon and Mars are meeting and will be separated by a distance of 3 degrees.
31/10 Uranus at opposition
Uranus is one of the outermost gas giants. In telescopes, it appears as a tiny green disc with no recognisable details. However, it can still be identified as a planet. Look for Uranus using a star chart or, even easier, with your telescope’s GoTo system. The planet’s disc can then be identified at a magnification of 150-200x.
November:
10/11 Mercury at greatest western elongation
Mercury is at its 19 degree greatest angular distance from the Sun. This results in it reaching its best morning visibility for the year. From the 10th, we can see Mercury rising above the eastern horizon at around 05:30. Emerging from the haze, it shines brightly below Venus.
11/11 The Moon occults v Virgo
You should get out of bed early on 11 November as, from 06:40 in the morning, a rare and very visible star occultation is taking place. The Moon occults the bright, mag 4 star, v Virgo.
12/11 Conjunction between Jupiter and Pluto
Jupiter and Pluto are passing each other and reach a proximity of up to 40 arc seconds on 12 November. Normally, it is difficult to readily find the former planet and current dwarf planet. This is because it is faint and undistinguishable from a star. However, Jupiter provides us with a good reference point for spotting Pluto without using GoTo mounts.
13/11 Conjunction between the Moon, Mercury and Venus
Daybreak presents a configuration to make every skywatcher’s eyes light up. Venus, Mercury and the almost-translucent crescent Moon can be found towards the east, in the constellation Virgo. The perfect chance for an atmospheric picture of the night sky.
16/11 Leonids
The Leonids reach their peak between 16 and 17 November. Along with the Perseids, they are one of the most famous meteor showers. There have been years in which these meteors have fallen like raindrops from the sky. This generally takes place every 33 years when the Earth runs into the Leonid cloud. In normal years, the shower does not exceed 20 meteors per hour at its peak. This year, the slender crescent Moon sets early on and we can enjoy meteors all night long without interruption.
19/11 Conjunction between the Moon, Jupiter and Saturn
The constellation Sagittarius finally disappears from the early evening sky, however today we can spot the five-day-old Moon and the planets Jupiter and Saturn in a neat group just above the horizon.
25/11 Conjunction between the Moon and Mars
The Moon and Mars today meet each other at a distance of around 6 degrees.
Astronomy highlights in summer 2020
May 27 2020, Marcus Schenk
Bright comets, fantastic meteors in August and multiple planets at opposition mean that the night sky in summer 2020 is full of astronomical treats.
As early as June, there will be two interesting comets to be seen, namely C/2020 F8 SWAN and C/2017 T2 PanSTARRS. The former is gradually moving from the southern night sky to the northern sky and the latter is maintaining its altitude as a circumpolar object. T2 PanSTARRS is great for telescope viewing – and you can even find it in a great position, right next to a well-known star. More on this later.
We wish you many exciting hours of viewing.
June
1 June SWAN comet
Spring 2020 was rich in comets, one of the most attractive and brightest of these being the comet C/2020 F8 SWAN. It remained in the southern sky in spring, climbed above the horizon at the end of May and can now be found in the northern sky.
4 June Mercury at greatest eastern elongation
Mercury reaches its greatest eastern elongation which, in this configuration, is 23 degrees. It can be seen in the evening sky just above the north-western horizon. When viewed through a telescope, you can see the planet almost half-illuminated.
5 June Penumbral lunar eclipse
This evening, as much as around 50% of the Moon plunges into the Earth’s penumbral shadow. The resulting penumbral eclipse is interesting astronomically but not spectacular visually, as the Moon is only obscured minimally.
We are unable to track the beginning at 19:45 CEST (17:45 UT) because the Moon is still below the horizon. At 21:24 CEST, at the time of its maximum eclipse, it is visible just above the south-eastern horizon. From now on, we can track its further progression until the Moon leaves the penumbral shadow at 23:04 CEST.
5 June PanStarrs comet
Another interesting comet which certainly warrants a quality photo is C/2017 T2 PanSTARRS. It was discovered on 01/10/2017 and has since been travelling around the Sun on a parabolic trajectory.
It is currently at magnitude 8 and is also visible with small telescopes and large binoculars. On 5 June, it will be visible at a distance of 1 degree from the bright star Dubhe (Alpha Ursae Majoris) in the Plough. It will therefore be very easy to find using any telescope and a wide-angle eyepiece or using a large telescope.
9 June Conjunction between Jupiter, Saturn and the Moon
There is rarely a more beautiful sight than this. At the start of the second half of the night, the Moon, Jupiter and Saturn are rising together over the south-eastern horizon. There are only 3 and 4 degrees between both planets and our satellite and together they make an attractive trio. To the right of this we find the constellation Sagittarius with its summer deep sky objects and, to the left, Capricorn.
13 June Conjunction between the Moon and Mars
From around 3:00 CEST (1:00 UT) we experience a conjunction between Mars and the Moon at an altitude of only 10 degrees above the horizon. A stunning sight, but who is this mysterious visitor? Almost invisible, Neptune joins them and can be found no more than 1.5 degrees above Mars with the help of binoculars.
19 June The Moon occults Venus
It is a rare event when the Moon slips in front of Venus today and occults it. However, this event is taking place during the day. But does this mean that you cannot somehow observe it? You can, but this event is more for experienced observers. At 9:55 CEST the Moon, with its narrow crescent shape, slips in front of Venus. Caution: The Sun is around 20 degrees to the east! Never look directly at the Sun with your eyes or using an optical instrument.
27 June June Bootids
The June Bootids meteor shower originates from the constellation Bootes. The number of falling meteors is small but variable. There have been years in which no meteors have been seen, however rates of 100 per hour have been seen on occasion. Because these meteors cause excitement, it is worth taking a closer look.
July
5 July Conjunction between Jupiter, Saturn and the Moon
Once night has fallen, the gas giants Jupiter and Saturn rise, drawing everyone’s gaze towards them at magnitudes of -2.7 and 0.1. Tonight the fully-illuminated Moon joins them, as the Moon was full only yesterday.
8 July Venus at greatest magnitude
Venus is currently located in the constellation Taurus or in the Hyades star cluster. Although it is only 30% illuminated, it is shining at magnitudre -4.4, the brightest magnitude achieved so far this year.
12 July Conjunction between Mars and the Moon
With 2.5 degrees between them, there is a conjunction between Mars and the Moon today. Both are in the constellation Cetus on the border of Pisces and rise after midnight. At sunrise they are 30 degrees above the horizon, they do not reach the meridian as the Sun will have already long risen by then.
12 Conjunction between Venus and Aldebaran
It is a special occurrence when a bright planet passes by a bright star. Events like these are very eye-catching and appealing to observe. On 12 July, Venus passes by the bright star Aldebaran at a distance of only 0.5 degrees. It is to be the closest encounter of any planet with Aldebaran in this century.
14 July Jupiter at opposition
Jupiter rises in the south-east as early as twilight and can be seen as a very bright object. Today it is at opposition to the Sun and can be admired throughout the entire night. A mere 619 million kilometres separate it from Earth and the light requires a little more than half an hour to reach us. Its visible diameter is 47 arc seconds and it crosses the meridian, and therefore achieves its best visibility, at 1:25 CEST (23:25 UT).
16 July Pluto at opposition
The former planet and current dwarf planet is at opposition and is shining at a magnitude of 14.2. Finding it with a telescope which only works with one accurate star chart is a challenge. Pluto is located between Saturn and Jupiter on these days, from which it is only 2 degrees to the west (on the left of the central Telrad ring).
17 July Conjunction between Venus and the Moon
A delightful sight in the morning sky in the form of today’s conjunction between Venus and the very narrow and almost 26-day-old crescent Moon in the constellation Taurus, close to the star Aldebaran.
21 July Saturn at opposition
July is the month of oppositions and today’s offering is Saturn. At magnitude 0.1, it will be shining much more faintly than its prominent colleague, Jupiter. However, Saturn is able to make up for this with its attractive rings, which we are able to see fully exposed in our view.
22 July Mercury at greatest western elongation
Whilst Mercury was at its greatest eastern elongation in June, it is now at its greatest western elongation. This means that it has now become an object in the morning sky, as it now rises before the Sun. From 4:30 CEST (2:30 UT), you should be able to see it at around 3 degrees above the horizon. At this time, the Sun is 8 degrees below the horizon.
28 July Delta Aquariids
The last event this month is the Delta Aquariids. These are shooting stars which appear to come from region containing the constellation Aquarius, at a maximum frequency of 25 per hour. The period after midnight, when the Moon has already gone down, is best suited for their observation.
August
1 August Conjunction between Jupiter and the Moon
Today there is a conjunction between the 12-day-old and almost full Moon and Jupiter.
9 August Conjunction between the Moon and Mars
This morning the Moon is approaching the planet Mars until it is around 2.75 degrees away. While Mars is in Pisces, the Moon crosses the border from Cetus to Pisces in the morning.
12 August Perseids
The absolute highlight of every August is the Perseids meteor shower. We are able to see up to 100 meteors per hour tonight. Admittedly, this is only because the Moon is not interfering. This year, we are able to view them during the first half of the night without it interfering. At 0:30 CEST (22:30 UT) the Moon rises above the horizon, the sky gets brighter and the faint Perseids are drowned out by Moonlight.
13 August Venus at greatest western elongation
Venus is the morning star and is currently at its greatest western elongation at a distance of 45 degrees between it and the Sun. When you view Venus through the telescope, it appears half-illuminated.
13 August Conjunction between the Moon and the Hyades
The Moon is in the constellation Taurus, close to the Hyades star cluster.
15 August Conjunction between Venus and the Moon
Anyone looking up at the sky in the early hours of the morning can see Venus close to the narrow crescent Moon. Both are in the constellation Gemini.
28 Conjunction between Jupiter, Saturn and the Moon
This evening there is a conjunction between the Moon, Jupiter and Saturn in the constellation Sagittarius. The trio is on the left, close to the well-known Teapot asterism. If deep-sky observation is not possible today, how about a tour of the lunar craters, culminating in a glimpse of both rulers of the solar system?
