Under the motto of the Science Year 2023, “Our Universe”, there was an opportunity at the Waldbröl Comprehensive School on 07 September 2023 to send radio signals on a journey to the moon and back. The...
Our cooperation in the field of research and promotion of young scientists with Macquarie University in Sydney is bearing fruit. The first components of the professional spectrograph for our large telescope were...
Our three identical observing stations will get company. In order to build a didactically meaningful bridge from the first scientific steps in the student lab to our large telescope, we will use two secondary stations...
The summer sky is full of fascinating star clusters and nebulae. But they are all surpassed in size, complexity, and beauty by the Cirrus Nebula. This mystical web stretches over more than six full moon diameters. This...
For the project days at Kopernikus-Gymnasium Wissen from Tuesday, July 18 to Thursday, July 20, 2023, an astronomy project was offered for the first time in several years. It was led by Cathrin Garbotz and Dr. Stephan...
Very massive stars can show a very strong mass loss in the final stage of their evolution. Here large amounts of stellar stellar matter and the core of the formerly massive star is exposed. Such stars are called Wolf...
Of course, there is no objective “right” or “wrong” in this case, but most amateur astronomers know a subjective one. The inclination of the earth’s axis in relation to the sun influences...
Thanks to a substantial public grant, we were able to finance a spectrograph for our large telescope. With this instrument we will be able to perform professional measurements of stars and participate in the search for...
With the instruments of the school observatory, research campaigns can be carried out on a professional level. Our colleague Christoph Quandt from Lübeck has been working on the study of the yellow hypergiant rho...
A week ago, a new supernova, or exploding star, was discovered in the Pinwheel Galaxy, 21 million light-years away. While this event can’t be seen with the naked eye, the equipment in the school lab makes it easy...
We had already feared it – again and again one warned us that our observatory could attract also dubious figures, but we dismissed this again and again as exaggerated fear. Today it happened. The first rocker...
After all the years of construction, we still experience special machines for our work from time to time. A vibrating plate was in our professional use at some point, but not in the fingers of our club members. Simon...
