Supernova remnant W44 revealed by XMM-Newton at high (light blue) and low (dark blue) energy X-ray emission corresponding to energies of 2–8 keV and 1.2-2 keV, respectively.
Knots of dense X-ray emission represent locations where the abundance of heavier elements is elevated. Pulsar PSR B1853+01 can be seen as the bright point source coloured light blue towards the top left of W44 in this image.
The striping is a result of the image processing.
