The color image shows X-ray sources in the western galactic hemisphere plotted in red, green, and blue, corresponding to soft (0.5-1.0 keV), medium (0.5-1.0 keV) and hard (1.0-2.0 keV) emissions, respectively. Credit & ©: Jeremy Sanders / MPE

The eROSITA Consortium has issued the survey’s second data release (DR2), nearly doubling the previously known eROSITA X-ray sources to two million.
