Coma Cluster
Show in archive: true
The Coma Cluster, an aggregate thousands of galaxies. The picture
is a mosaic of 12 partially overlapping pointings obtained with
the EPIC-pn camera. The cluster was chosen during XMM-Newton's
performance verification phase to prove the observatory's ability
to map and analyse data from large extended X-ray sources.

region of the Coma Cluster of galaxies, highlighting the X-ray
hardness and corresponding temperatures around the giant
elliptical galaxies NGC 4889 and NGC 4874 and the gas in the
central part of the cluster. Courtesy U. Briel, Max-Planck
