After the bright summer nights, it gets dark much earlier again in September. Most of the constellations can already be seen at around 21:30. First to fall vertically above us is the bright star\u00a0Away<\/strong>\u00a0up. If you look there again later, when it has become completely dark, you will also see the small diamond-shaped constellation\u00a0Lyre<\/strong>\u00a0in which Vega is the brightest star. If you do not see Lyra, you may not have seen Vega, but perhaps the star Atair (constellation\u00a0Eagle<\/strong>) or Deneb (constellation\u00a0Swan<\/strong>) in their sights. Vega, Atair and Deneb together form a large triangle called the \"summer triangle\". In the middle of the summer triangle and slightly to the left of it are the small constellations\u00a0Arrow<\/strong>\u00a0and\u00a0Dolphin<\/strong>. Neither of them have any bright stars, but because they are so small, their figures stand out at first glance. Now the\u00a0Milky Way<\/strong>\u00a0as a pale, shimmering band high above our heads. Both the western part of the sky with the setting early summer constellations and the eastern sky with the rising autumn constellations are poor in bright stars. In the constellation of Pisces\u00a0Saturn<\/strong>\u00a0and right next door you can Neptune<\/strong>\u00a0observe.<\/p>\n\n\n\n

On September 7, a total\u00a0Lunar eclipse<\/strong>\u00a0takes place. The moon is already eclipsed above the eastern horizon in Central Europe. By the end of totality at 20:53, it is just under ten degrees above the horizon. At 21:57, the moon leaves the Earth's umbra again. See also the point Events<\/a> on our homepage.<\/p>\n\n\n\n

The planets in September 2025<\/strong><\/p>\n\n\n\n

Mercury<\/strong> is not observable in September.<\/p>\n\n\n\n

Venus<\/strong> is on its way south along the ecliptic. It runs from the constellation of Cancer to the constellation of Leo. We can still see Venus as a bright morning star. On 19.9. it is directly next to the main star Regulus and the crescent moon is just in front of Venus. In the afternoon of September 19, the moon will cover Venus in the daytime sky.<\/p>\n\n\n\n

Mars<\/strong> passes through the constellation of Virgo, but this remains hidden in the bright sunshine.<\/p>\n\n\n\n

Jupiter<\/strong> in the constellation of Gemini rises at midnight. On 16.9. the waning moon is close to Jupiter.<\/p>\n\n\n\n

Saturn<\/strong> reaches its opposition this year on 21.9. It rises in the evening, is in the south at midnight and sets in the morning. On September 8\/9, the full moon will pass Saturn. We are currently looking almost exactly at the edge of Saturn's rings. There will also be interesting events involving Saturn's moons with transits in front of the planet's disk and shadows cast.<\/p>\n\n\n\n

Uranus<\/strong>\u00a0in the constellation of Taurus now rises in the early evening hours, and it is worth observing it with binoculars from around midnight.<\/p>\n\n\n\n

Neptune<\/strong> reaches this year's opposition to the sun on September 23. The distant planet is currently in the constellation of Pisces. To see it, you need good binoculars or a telescope.<\/p>\n\n\n\n
