- 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. - Solar astronomy at Piesberg
"Sunshine, everything's good" – that sums up Sunday, September 7, 2025, which we of "kosmos-os" spent at Piesberg. The Museum of Industrial Culture had invited the Osnabrück residents to the "Bergfest" (mountain festival) and asked us to be there with an information booth. Of course, we agreed.
