Abell 39 is a planetary nebula with low surface brightness in the constellation Hercules. It shines predominantly in the blue light of the double ionized atomic oxygen [OIII]. It is assumed that the nebula is about 6800...
American scientists point to a problematic development in observational astronomy. Large telescopes have enabled novel research activities that were previously unthinkable, including the provision of large datasets. As...
Frau Brigitte Thome-Bode from Hannover donated the complete observatory of Hans-Joachim Bode to the STScI. The first-class ensemble of several lens and reflector telescopes, a very heavy mount (we now know how the...

The paved floor for the school lab and the rest of the area in front of the service building is finished. Metten Stein+Design from Overath supplied 280 square metres, which were then laid by experts. As soon as the...
Noctilucent clouds are accumulations of ice crystals above the mesosphere in the mesopause. There the absolute minimum temperature of the Earth’s atmosphere is reached. They appear at a height of 81 to 85 km...
Finally we can start with the installation of our large telescope. In two days the mounting and the telescope were set up separately to install both later one after the other in the telescope tower. Screws and small...
The Medusa Nebula (PK 205 + 14.1) in the constellation of Gemini was only discovered in 1955. Its name comes from the snake-like gas filaments which remind of the hair of Medusa. For a long time, the nebula was thought...
The total lunar eclipse in the early morning of 21 January 2019 was to be observed in the Bergisches Land with clear sky in its full course. The cover picture shows the view of the moon entering the core shadow of the...
Leg and back muscles were tested with a pickaxe, shovel and concrete. The SchoolLab will have three identical observation stations plus a dome observatory. All stations need power and data connections to the three...
