Astronomers have nearly doubled the number of known cosmic X-ray sources, offering the most comprehensive public view yet of the universe's hottest and most energetic objects.
The second major public data release from the German-led eROSITA X-ray telescope contains a catalog of nearly 2 million X-ray-emitting objects, including supermassive black holes, galaxy clusters, stars and other extreme cosmic phenomena. The unprecedented dataset — called DR2 — will help astronomers investigate how black holes grow, galaxies evolve and the universe's largest structures formed, according to a statement from the Max Planck Institute for Extraterrestrial Physics.
