In the dream of the summer night under the stars: The moon shines coppery late in the night of Friday (27.7.22.22) and Mars appears large, red and bright. The extremely rare astronomical event falls on a hot summer, however not clear summer night everywhere. "It's a great opportunity to educate people about the wonders of the sky," says astrophysicist Dominik Elsässer of the Sternfreunde Association (VdS) in Heppenheim in southern Hesse
many observatories, planetariums, astronomical badociations and research institutes invite you to watch the drama. at. Astronaut Alexander Gerst of the ISS space station has a good special view. Top of Page Questions and Answers:
What Happens to the Moon?
A lunar eclipse occurs only at the full moon when the sun, the earth and the moon are aligned. The moon plunges completely into the shadows that the sunlit earth throws into space. According to astronomers, Friday sees the longest visible total lunar eclipse of the 21st century: it takes one hour and 43 minutes. This duration is surpbaded only at lunar eclipse on June 9, 2123 – about three minutes. "Then she almost reached the maximum possible of one hour and 47 minutes," says astronomer Carolin Liefke of the VdS and the Heidelberg Astronomy House
Why the moon at the # Does the shadow of the earth shine from coppery red to orange? The shortwave blue light waves of the sun's rays are completely dispersed in the Earth's atmosphere, says the German Aerospace Center (DLR). The long-wave red light, however, is broken and directed towards the moon. He falls on the surface of the moon in the shade, adds Elsässer. The moon is flickering red, some speak of a "blood moon".

Why is Mars so red and bright?
] Mars, also known as the Red Planet, is as close to Earth on Fridays as it is rare – just 58 million kilometers from our planet. That's the minimum distance, as Liefke says. It was the last time that 15 years ago, according to the DLR. Unlike Earth, Mars does not need it on its orbit farther around the Sun, but nearly two years. When Earth exceeds Mars on the inner orbit and Mars is relatively close to the Sun, it is particularly bright and relatively large in the sky.
What are the weather forecasts for the night?
High summer temperatures and especially unobstructed view expected. In the southeast and east, however, the clouds make visibility difficult, as explained by meteorologist Sebastian Schappert of the German meteorological service of Offenbach. In some places, there may even be showers with heavy rain and thunderstorms. In the west and the north is to be expected with the tropical nights – it's over 20 degrees. In the evening, it is still 25 to 27 degrees.
What can you see when?
The show begins with the appearance of darkness in the evening. In Munich, the moon rises to 20.48, in Hamburg to 21.16. Then it takes a few more minutes until the moon is completely submerged in the shadow of the Earth and the total lunar eclipse begins. The middle of total darkness is reached at 22.22 and the end at around 23.13. "The moon is noticeably redder and darker," says Liefke. "It can be clearly seen that he looks different from the usual."
The lunar eclipse ends shortly after midnight. "March, however, is seen all night." At the height of the lunar eclipse, the Moon and Mars are still deep above the southeast horizon. At the end of the darkness, it looks better: then the celestial bodies are much higher, it is really dark and you can – if time plays the game – enjoy their reddish glow. After midnight you will see the moon leave the shadow of the Earth. It becomes more and more clear. At 1.30 in the morning, the moon has completely left the darkness
Where should we look in the sky?
According to DLR, the lunar eclipse is best seen in the south and east of Germany. To the south, the moon is the highest, to the east it rises earlier and the darkness is more complete. No matter where, it is important in any case, a view to the southeast at the horizon – also largely free of terrestrial light sources. At the center of the total lunar eclipse, Mars is visible about six degrees south of the moon, just above the horizon. Then you can try to photograph the two together.
How often do these two events collide?
A total lunar eclipse similar to that of July 27 and the same state of Mars against the Sun and the Sun. closer to the ground – according to Stefan Krause's calculations of the public observatory Bonn will reappear on average only in about 105 000 years.
