At kosmos-os, enthusiastic and committed astronomers from Osnabrück and the surrounding area meet to share this fascination with others. Our "Sternstunden" make astronomy tangible for everyone - wander together into the distance...

- The occultation of Venus by the Moon on 19.09.2025
Alle Planeten und ebenso der Mond bewegen sich auf Bahnen nahe der Ekliptik. Da die Mondbahnebene leicht gegen die der Planeten geneigt ist, kann es von Zeit zu Zeit zu Bedeckungen einzelner Planeten durch den Mond kommen. Solch eine Bedeckung war für den 19. September 2025 vorausberechnet. Die Beobachtung eines solchen Ereignisses stellt ein astronomisches Highlight dar, denn man kann dabei Himmelsmechanik live erleben. - The lunar eclipse on 09/07/2025
Lunar eclipses are not very common. To do this, the moon must dip into the shadow of the Earth, which is illuminated by the sun. This can only happen if the sun, earth and moon are sufficiently in line. The plane of the moon's orbit around the earth is inclined by about 5.2° compared to the earth's orbit around the sun (ecliptic). Therefore, the full moon does not dip into the Earth's shadow every time it orbits. Only when the full moon is sufficiently close to one of the two intersections of the ecliptic and the moon's orbit (lunar node) does a lunar eclipse occur.
