Messier 81 is a spiral galaxy that lives 12 million light years away from the Milky Way.
Messier 81 is home to a bunch of short living, but hot blue stars, she has also been having interactions with Cigar Galaxy, where they both were stealing hydrogen from each other, showing there rivalry with each other. This is also happening with NGC 3077, which causes more problems.
