Messier 81 also known as Bode's Galaxy, is shown here with its smaller companion galaxy, Messier 82. Messier 82 is very interesting in the fact that it is in the throes of a violent explosion. Large streamers and filaments can be seen streaming from it in Hydrogen Alpha light. This picture was done in normal visible light, so they are not as prominent, but still can be seen. It is one of the great mysteries of science as to why this galaxy is exploding. The current theory has it resulting from a close pass from the larger spiral, M81.
