![[M82 in X-rays, XMM-Newton]](http://messier.files.wordpress.com/2008/07/m82_ranalli_med.jpg)
M82 was captured in X-rays by a telesope on ESA’s XMM-Newton satellite, featuring its powerful outflow. M82 is actively forming stars, and exhibits a several kpc large outflow, made up of very hot gas produced by supernova explosions. The image has been produced from EPIC data; the colours indicate the energy of the X-rays (red: 0.4-1 keV; green: 1-2 keV; blue: 2-8 keV). The central regions of the galaxy appear blueish because of heavy absorption.
