M81 and M82

The spring brings out some great galaxies. This is the first iteration of a long-term project I'll be working on with respect to these two galaxies.

M81 is on the right, lies around 11.7 million light years away and harbors around 250 billion stars. M82, on the left,  is also called the "Cigar Galaxy" lies at about the same distance as M81. The two galaxies are seperated by about 150,000 light years.
