"Unveiling the Universe: Largest X-ray Survey Reveals 1 Million High-Energy Objects"

The eROSITA sky survey has released the first data, revealing almost 1 million high-energy cosmic sources, including over 700,000 supermassive black holes, in an X-ray view of half the sky over Earth. This constitutes the largest-ever catalog of the universe's most powerful sources of energy, and the data could help answer some of cosmology's biggest questions. The release also details the largest known structures in the universe and includes almost 50 scientific papers published across a range of topics. The eRASS1 data consists of eROSITA telescope observations conducted from Dec. 12, 2019, to June 11, 2020, and has been made available to scientists worldwide.
