XMM-Newton has again observed the Coma Cluster of galaxies, with far longer exposures

Copyright: ESA

Certain regions were observed for 22.6 Ksecs instead of 3.4 Ksecs originally, and with a lower proton background. Shown at the Delta Review, the new EPIC-pn image covers the 0.3 to 2.0 keV energy range and clearly discerns far more sources. The difference is striking particularly in the north/west (upper-right) corner. Courtesy U.Briel.
