Russell Croman Astrophotography  



Chaotic Galaxy M82

About This Photograph

Here we find a galaxy out of sorts, the victim of a recent gravitational assault by nearby galaxy M81. This has apparently triggered a burst of star formation within M82. The resulting activity, perhaps including a high rate of supernova explosions, is driving copious amounts of red glowing hydrogen gas and other material into intergalactic space.
