Located about 23 million light-years from Earth, M51 is a spiral face-on galaxy 60,000 light-years across. The redish color in the arms of the spiral are from HII gas. M51 is
believed to be robbing matter from its smaller companion galaxy, NGC
5195, seen just below it. Two other tiny galaxies can be seen near
NGC5195 - IC 4278 to the right and IC 4277 to the right and below
it. North is at the top.
