About this Image
The image shows an XMM-Newton EPIC image (colour) overlayed
onto an optical Digitised Sky Survey image of the spiral galaxy M101
(greyscale). The XMM-Newton image comprises data from the MOS and pn cameras,
and is false coloured as follows: low energy (0.2-1.0 keV) photons are shown in
red, medium energy (1.0-2.0 keV) in green, and high energy (2.0-12 keV) in
blue. The Digitised Sky Survey image of the galaxy was taken in the blue
optical band and has been displayed in inverted greyscale (areas of emission
are seen as black against a white background) so that the X-ray image can be
seen through it.
The combined image shows correpondence in the spiral arms between
X-ray and optical emission. The nucleus
is also clearly seen in the X-ray particularly the circumnuclear region in the low energy emission.
