Astro-highlights – Summer 2021

June 4 2021, Marcus Schenk

A solar eclipse after six years, the large planets in opposition and the August meteor shower is visible without any moonlight.

If you’re not looking at the stars this summer, you’re missing something. The sky chart “Astro-highlights – Summer 2021” shows you all the significant celestial events at a glance so that you don’t miss anything. Additional information about these events can be found below the graphic.

We wish you lots of observing pleasure!

June

10/6 Partial solar eclipse

The last partial solar eclipse in Europe was visible on 20 March 2015. The Moon covered up to 80% of the Sun’s disk then. The next solar eclipse occurs on 10 June. It is an annular solar eclipse visible in Greenland and Northern Canada, and partially visible in Central Europe. It is relatively unspectacular, only covering a few percent of the Sun.  The further north you are, the higher the degree of the eclipse. In Munich, only 6.3% of the lunar limb touches the Sun, whereas in Hamburg it is 17.3%. The eclipse begins at 11:35a.m. and ends at 13:22 (depending on the exact location). Caution: Only observe the Sun with a suitable solar filter, which you can purchase from our online shop.

Degree of coverage at our Astroshop sites:

Landsberg, Germany: 6.56%

Marseille, France: 2.7%

Malaga, Spain: 1.3%

Warsaw, Poland: 9.9%

Hasselt/Genk, Belgium: 14.9%

Aveiro, Portugal: 9%

Palermo, Italy: 0%

12/6 The Moon meets Venus

The faint waxing crescent Moon and brilliant Venus appear low to the west shortly after sunset. To the upper left, you will discover Mars. If you are observing with binoculars, a short diagonal sweep to the upper left will bring you to the Beehive Cluster M44.

13/6 The Moon meets Mars

Today the Moon rises higher and joins the planet Mars, which it passes at a distance of 1.8 degrees. Both make a beautiful view through binoculars.

27/6 June Bootids

The June Bootids meteor shower originates in the Boötes constellation. The number of falling stars is small but variable. There have been years in which no meteors were sighted at all, but there have also been occurrences of 100 per hour. This meteor shower is exciting and worth taking a closer look at.

27/6 The Moon meets Saturn

Those who want to see the big gas giants will have to wait until midnight in June. Saturn is currently in the constellation of Capricorn, the horned mountain goat that climbs the meridian at the peak of the sky before dawn. The Moon passes Saturn today at a distance of about 9 degrees.

29/6 The Moon meets Jupiter

On its way along the ecliptic this morning, the Moon passes about 5 degrees below Jupiter. The large differences in brightness between the Moon, Jupiter, Saturn and the brightest stars are interesting to observe.

July

8/7 The Moon meets Mercury

Mercury hovers low over the horizon in the morning sky for the next few days. We can observe it with a perfect horizon view well after 4a.m., close above a flat landscape. The crescent Moon joins it 2.5 degrees above. The new Moon is in two days’ time.

12/7 The Moon meets Venus and Mars

As dusk falls, the Moon and the two planets Venus and Mars make for a delightful sight. The pouncing Leo seemingly about to snap at the three objects. You can admire both celestial bodies through binoculars in one field of view. It’s also a great opportunity to take a photo at dusk.

18/7 Pluto in opposition

Pluto is a dwarf planet that is not easily visible and a challenge for larger telescopes.  Once the 9th planet, it was stripped of its planetary dignity in 2006, but of course our enthusiasm for the solar system’s outpost remains undiminished. If you want to set your sights on it, the best time to do so is during its opposition. Use your GoTo mount’s controller and a star chart to distinguish it from the background stars.

Coordinates for GoTo controller (23:59 CEST): RA: 19h49m59s, Dec: -22°38′

19/7 Golden Handle

The Golden Handle of the Moon? It does exist, but only during a certain lunar phase. Appearing like a handle of light, it is an effect caused by light on the lunar surface, along the terminator line. We are gazing at the Mare Imbrium in the Sinus Iridum crater region and the Montes Jura. Here, the sun rises at the day-night boundary. While the crater is still in darkness, the peaks of Montes Jura catch the sunlight at their summits. A golden ring in the darkness. Best seen between 18:00 and 21:30 CEST.

20/7 The Moon meets Antares

This evening, the Moon remains to the east of the star Antares. It is a red supergiant and shines bright with a reddish hue 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.

21/7 Venus meets Regulus

With a good view of the horizon, you will discover Venus at the foot of the constellation Leo after sunset. In the immediate vicinity you will find the star Alpha Leonis, better known as Regulus. The name means  “little King” or “prince”. If you’re thinking of little Simba and the Lion King, you’re probably right.

24/7 The Moon meets Saturn

Shortly before midnight, the constellation of Capricorn appears above the horizon. It is easily recognised by its bowl-like shape. The Moon passes below Saturn at a distance of 4.6 degrees on this night. If you focus on Saturn with binoculars, you will notice a magnitude 5.8 star on your left.

25/7 The Moon meets Jupiter

One day after its encounter with Saturn, the Moon meets Jupiter in the constellation of Aquarius. On this night, the two celestial bodies are separated by 5.5 degrees. Next month, the two gas giants will be in opposition to the Sun.

28/7 Delta Aquariids

The Delta Aquariids are a meteoroid stream that appear to originate in Aquarius. With around 25 meteors per hour, however, it trails far behind the August meteor shower in terms of prominence. Because the Moon phase is very high, the only suitable time for observation is before moonrise.

August

1/8 Jupiter’s moon Ganymede covers Europa

If you take a look through a telescope after Jupiter rises, you will notice the two moons of Jupiter, Europa and Ganymede.  Like double stars, they appear close to each other. At 0:00 CEST, Ganymede partially obscures the somewhat smaller Europa, and at around 2:00 CEST, the two moons go their separate ways again.

2/8 Saturn in opposition

Due to the low position of the ecliptic plane, Saturn has remained low above the horizon in recent years. In 2019, it reached a height of about 20 degrees. During its opposition this year, we can observe it at an altitude of 24 degrees. Over the next few years, Saturn will continue to climb higher. The higher its position, the less we have to contend with atmospheric air turbulence.

On 2 August it reaches its opposition and shines brightly in the sky with a magnitude of 0.1. In doing so, it competes with the brightest stars. We recognise it by its yellowish colour and calm glow. Its ring opening is 18 degrees and if we look at the ring system from the north, we can easily identify the Cassini division.

11/8 The Moon meets Venus

A gaze into the evening twilight is well worth it, Venus shines brightly low in the west with the narrow crescent Moon just above it.

12/8 Perseids

Enjoy the most beautiful shooting stars of the year. The Perseids can be seen at their best this year, there will be a new Moon and dark skies all night while we observe them. The meteor shower is most intense during the morning hours of 12 August. At this time, up to 100 shooting stars fall through our atmosphere each hour at a speed of approximately 216,000 km/h. The best observation time is between 22:00 and 4:00 CEST.

18/8 Mars meets Mercury

An extremely close encounter for seasoned observers. At dusk on 18 August, Mars and Mercury meet only about 3 degrees above the horizon. The sun is barely below the horizon at this time.

20/8 Jupiter in opposition

You can already see Jupiter rising flat in the east at twilight, at magnitude -2.8, a bright object that is hard to miss. But the evening sky has even more to offer in terms of conspicuous objects; the moon and Saturn in close proximity and radiant Venus close above the western horizon.

Today, Jupiter draws all the attention – it is in opposition to the Sun and can be admired all night long. It is now separated from Earth by 600 million kilometres and the light takes just over half an hour to reach us. Its apparent diameter is 49″, it reaches its meridian passage and thus its best visibility and highest position at 1:14 CEST.

Astronomy Highlights in Winter 2020/21

December 2 2020, Marcus Schenk

An extremely close encounter between Jupiter and Saturn, Mars and Uranus together in your field of view and the Geminids coincide with a new Moon. Once again there are all sorts of reasons to take a look and admire the starry sky. In the infographic “Astronomy Highlights in Winter 2020/21”, you have all the important celestial events occurring in the next three months at a glance. We wish you lots of observing pleasure!

December:

13/12 Geminids

If the evening sky is clear, take a look to the south. The Geminids meteor shower will appear to be originating from the constellation Gemini. Or to be more precise: from a point two degrees above the star Pollux. The best time for observing is between 21:00 and 06:00 CEST. With 120 meteors per hour, the Geminids are among the most active meteor showers. We are especially lucky with the timing this year since we have a new Moon and so we can observe, undisturbed, all night.

13/12 Conjunction between the Moon and Venus

Are you an early bird who can think of nothing better than to gaze at the stars in the early hours? This morning it will be worth your while. From around 05:30 GMT (06:30 CET) you can see lustrous Venus in the sky and, underneath it, the delicate crescent Moon – since the very next day we have a new Moon. This weekend is perfect for deep-sky observing.

17/12 Conjunction between the Moon, Saturn and Jupiter

We are able to enjoy this attractive event thanks to the fact that at the moment it gets dark early. At dusk we see a conjunction between Jupiter, Saturn and the young waxing crescent Moon. The two gas giants accompanied us throughout last summer and every evening they were the brightest objects in the southern sky. Now they disappear early and let the winter sky take centre stage.

21/12 Ursids

The Ursids are a meteor shower on which you can keep your eye on all night. This is because they originate from the constellation Ursa Minor, from which these meteors also get their name. These beacons speed across the sky considerably slower than the Perseids – at around 35 kilometers per second.

21/12 Winter solstice

21/12 Conjunction between Jupiter and Saturn (note: they appear very close together)

Are you observing the Star of Bethlehem today? It’s the highlight of the month and you definitely shouldn’t miss it. On 21 December, coinciding with the winter solstice, Jupiter and Saturn present us with an unusual spectacle since in this conjunction they are just 5 arc minutes apart. A truly rare sight.

Let’s step back in time: Jupiter and Saturn also met one another in the year 7 BC. In that year a total of three such conjunctions in constellation Pisces between these two planets occurred. Scientists can still prove that today. We can assume that, due to its distinctive nature, this was what became to be known as the Star of Bethlehem. An interesting association so close to Christmas, isn’t it?

How about observing both of them through your telescope in a single field of view? You need to be sure to take up your observing position early. Preferably around 17:00 CET when the gas giants are sufficiently high in the sky, since in less than 1.5 hours they will disappear into the haze on the horizon.

21/12 The Moon occults mag 4.3 star

At 20:04 GMT (21:04 CET) the Moon occults the 4.3 mag star 30 PSC, which belongs to the constellation Pisces. What is especially beautiful is that the Moon moves closer to the star from its unilluminated side, so suddenly the star disappears as if it was simply switched off. At 21:15 GMT (22:15 CET) it twinkles again from the other side of the Moon.

23/12 The Moon near Mars

In October Mars stood in favourable opposition and was spectacular to see. Now it is in the constellation Pisces where it can be observed during the first half of the night. This evening the Moon joins it.

24/12

Happy Christmas!

27/12 The Moon near Aldebaran and the Pleiades

Even people who do not concern themselves with the night sky notice the Pleiades, and they often mistake them for Ursa Minor. Observers of the sky know differently: it is the best-known open star cluster which has been observed by mankind for thousands of years and which has a special significance for many cultures. Tonight the Moon meets up with the Pleiades and with Aldebaran, the brightest star in Taurus.

January:

02/01 Quadrantids

The Quadrantids is a meteor shower originating from the constellation Boötes. The new year starts with an astronomical performance which delivers around 120 meteors per hour. The radiant, from where the shooting stars appear to originate, only appears after midnight. Unfortunately, this year the bright Moon disturbs the show, since full Moon was only three days ago.

03/01 The Moon near Regulus

Today the Moon and Regulus can be seen, with a separation of 4 degrees. The name Regulus means ”little king“ in Latin. Because of its proximity to the ecliptic, it regularly meets the Moon.

07/01 The Moon near Spica

Spica is a massive blue star, a variable star, and at the same time a binary star system. 262 light years away, 13,000 times brighter than the Sun, and 7.5 times larger than the radius of the Sun, it takes 16th place in the list of the brightest stars in the sky. Spica is located at the ear of grain that Virgo holds in her left hand, this is also the origin of the star’s Latin name. On 7 January the Moon is nearby.

11/01 The Moon near Venus

On the morning of 11 January dawn is nearly over when Venus rises at 06:00 GMT (07:00 CET) and meets the slender crescent Moon above. At this point the Sun is still just 9 degrees below the horizon.

20/01 Mars near Uranus

The planet Uranus is theoretically visible with the naked eye. However, in practice the 2.9 billion kilometre distant planet is not so easy to find. The problem is that it is so small that it can be difficult to distinguish from a star. This is tricky with binoculars, but is a little easier with a telescope where you can distinguish one ”star“ with a minimally-greater diameter from another. This evening you can find Uranus more easily because it comes near Mars at a distance of 1.5 degrees.

If you use an eyepiece with a longer focal length then you can admire both in your field of view.

21/01 The Moon near Mars

Today the Moon passes Mars at a separation of 5.5 degrees.

24.01. Mercury at greatest eastern elongation

Mercury orbits the Sun so quickly and so close, that we cannot always observe it. However now Mercury is once again at a greater angular distance of 18 degrees from the Sun. That’s not a large number, but we can nonetheless observe it during its half phase. Mercury is to be seen in the evening sky shortly after sunset. Whatever you do, wait until the Sun has set. Then you will discover Mercury just above the western horizon.

27/01 Mercury at best visibility

Today Mercury reaches its highest position in the night sky, and with it its best evening visibility. From tomorrow its orbit sends it lower, back towards the horizon.

February:

03/02 The Moon near Spica

Once again, this morning the Moon passes by star Spica in Virgo. What is behind these frequent encounters? The ecliptic lies above Spica which ensures that the Moon frequently comes to visit.

06/02 The Moon near Antares

This morning, the 23-day old and waning Moon meets Antares, the brightest star in the constellation Scorpius.

19/02 The Moon near Mars, Pleiades and the Hyades

A fine sight in the evening sky: the Moon visits the constellation Taurus and remains in a position between the Hyades and the Pleiades. Both are ancient open star clusters that people have been observing since time immemorial. Mars joins in too. Isn’t this get-together worth a photo?

23/02 The Moon near Pollux

In the last days of the month the waxing Moon wanders from the constellation Taurus towards Gemini. This evening it meets Pollux, a red giant star that is 34 light years away.

26/02 The Moon near Regulus

Just a few hours before the full Moon, our satellite meets up with Regulus, the brightest star in Leo. When dusk is over we see an interesting image in the starry sky: in the west the autumn constellations are disappearing from view, in the south the winter constellations reach their highest point, and in the east spring is climbing over the horizon.

More info on each highlight in the graphic can be found below.  We wish you hours of observational enjoyment and fun, as well as a warm Summer!

 

June

Jupiter in the Evening Sky

Last chance to see Jupiter in the evening.  Our solar system’s biggest planet will sparkle in the western sky.  An arc second of 35″ is enough to recognized details of the planet, for example, the cloud bands and the (in)famous Great Red Spot, or Jupiter’s moons.  The planet will be visible in the evening until the end of July.

 

3rd of June – Saturn in Opposition, Awesome Rings and Ophiuchus

On the 3rd of June, Saturn will stand in opposition, being visible for the entire night.  The planet will be roughly 1.35 million km (840,000 miles) away from Earth, offering us a perfect impression.  Saturn will enthrall us with a perfect perspective of its rings at 26 degrees.  The gas giant will rise at around 9 PM and create a wonderful constellation along with Mars and Antares.

 

11th of June – Our Moon meets with Jupiter

During dusk, a look to the west will be very rewarding.  There, you will see a waxing Moon along with a shining Jupiter above to the right.  Both objects on this evening will be only 2° away from one another.  With a camera, a telephoto lens and a clear evening sky, you’ll have everything for a unique photo.

 

21st of June – Summer Solstice

The 21st of June is the longest day and shortest night of the year.  The sun will set after 9 PM (depending on your coordinates) and will rise again after 5 AM.  The night won’t be extremely dark by astronomy standards, as the sky will always appear dimly lit.  The Earth will be at its greatest distance to the Sun in its elipse and the Earth’s tilt of 23.5° will result in a very high angle of incidence.  With hotter days on the horizon, we will flock to our parks, lakes and rivers for some summer fun.

 

International Space Station Visible 

The ISS will be visible during the summer months, but will vary depending on your location.   Luckily a handy website from NASA allows you to check ISS visibility in your area.  Check it out for more info!

 

26th of June – The Moon Obscures Neptune

On the 26th of June, for those in Europe, the Moon will move in front of Neptune.  Around 1 AM, Neptune will disappear behind the lit Moon disk and will appear again on the non-illuminated side at around 1:30 AM.

 

July

4th of July – Space Probe Juno Reaches Its Destination

The space probe Juno was launched  on the 5th of August 2011 and will arrive at Jupiter after a five year trip.  The probe will take up a polar orbit in order to research Jupiters atmosphere and magnetic field.  At mission’s end in October of 2017, the probe will send itself plunging into the planet’s atmosphere, only to be crushed by the atmosphere’s massive pressure.

 

7th of July – Pluto in Opposition

Once there was a planet that was indeed only a dwarf planet.  Pluto will be especially interesting to observe on the 7th of July as it stands in opposition.  The 2,374 km large body is 4.4 million km away and will shine only at a 14.1 mag, like a tea light between the larger plants.  You will only be able to see the dwarf planet with a large telescope, but even there it won’t be able to differentiate itself from stars.  With Universe2go, however, you will be able to get a full experience of Pluto without a telescope.  You can even see its heart, which the space probe Philae discovered last year.

 

9th of July – A Lunar Meeting with Jupiter

At only 4.5° apart, the Moon will encounter Jupiter this evening on the western horizon, providing a good photo op for those looking for a unique image.

 

August

12th of August – Conjunction of Saturn, Mars and the Moon near Scorpio

Mars, Saturn and the Moon will meet up near Antares, providing an intriguing sight.  Lined up like a string of pearls on the 12th, we will find them close to Antares, the primary star of Scorpio.  Observations and images of this quartet will be fruitful to say the least!

 

12th of August – Perseid Meteor Shower

In the night of the 12th into the 13th of August, the Persied Meteor Shower will reach its peak.  Up to 100 meteors per hour will rain down and thunder through our atmosphere at an unbelievable speed of about 216,000 km/h (134,000 mph).  So, do you hold out and stay up all night or get up early?  Since the shower will peak between 10 PM and 4 AM, the choice is yours.  The Moon will disturb the night sky at the beginning, but will set after midnight, allowing us enjoy darkness in all its splendor!

We can thank the comet 109P/Swift-Tuttle for this meteor shower, which in its orbit around the sun has lost a portion of its mass.  Every year that the Earth crosses the comet’s orbit in August, the Perseids occur in our night sky.

This year, we can expect even more meteors, since the Earth has moved closer to the path of the comet.  As a result, astronomers believe we will see a greater number of meteors than in previous years.  Is that not enough reason to check it out?

 

27th of August – Conjuntion of Venus and Jupiter in the Evening 

Keep an eye on Jupiter and Venus this evening.  Both planets will race across the sky, as Venus overtakes the gas giant to the north.  Before those in Europe even see their closest encounter, both will set in the evening in the western horizon, allowing those in the western hemisphere a fantastic show!

It is best to go out with binoculars at dusk, but be sure to avoid looking into the Sun by waiting for our star to set.
