This is how the energetic universe looks like through eROSITA X-ray telescope


Our deepest view of the X-ray sky.



The eROSITA telescope onboard SRG has recently captured a stunning view of the entire sky- revealing the nature of the hot universe. The view is about four times deeper than the previous all-sky survey by the ROSAT telescope 30 years ago and has yielded around ten times more sources: nearly as many as have been discovered by all past X-ray telescopes combined. 


Over 182 days, the eROSITA X-ray telescope onboard SRG has completed its first full sweep of the sky. This new map of the hot, energetic universe contains more than one million objects, roughly doubling the number of known X-ray sources discovered over the 60-year history of X-ray astronomy.


Peter Predehl, the Principal Investigator of eROSITA at the Max Planck Institute for Extraterrestrial Physics (MPE), said, “This all-sky image completely changes the way we look at the energetic universe. We see such a wealth of detail – the beauty of the images is stunning.”
