Both images show the same area of the sky.

Both images show the same area of the sky. Initial results from the x-ray space telescope eROSITA published Astounding Insights into the Life of Young Stars and Massive Black Holes Two years ago, the eROSITA x-ray telescope flew into space as part of a Russian-German cooperation to create the most comprehensive sky map in x-ray frequency range to date. The German eROSITA consortium, which includes Universität Hamburg, has now published the first data that the x-ray telescope, which was attached to a satellite, gathered. The publication of the first eROSITA data will be flanked by 35 further scientific publications to appear in a special edition of the journal Astronomy and Astrophysics . These are already publicly accessible. Six of these publications were spearheaded by researchers from Universität Hamburg and they concentrate on the activity of stars as well as the effects of black holes on their surroundings.
