Shown are the EPIC-MOS X-ray contours of the Sirsic 159-03 cluster of galaxies, superimposed on an optical (Digitised Sky Survey) view of the corresponding region. The contours map the X-ray intensity distribution of the intra-cluster gas and the bottom graph illustrates the radial temperature profile of this X-ray emitting material. Courtesy J.
