Messier 79 (also known as M79 or NGC 1904) is a globular cluster in the Lepus constellation. It was discovered by Pierre M?chain in 1780. M79 is at a distance of about 41,000 light years away from Earth and 60,000 light years away from the Galactic Center.
Like Messier 54 (the other extragalactic globular on Messier's list), it is thought that M79 is not native to the Milky Way galaxy at all, but instead to the Canis Major Dwarf Galaxy which is currently experiencing a very close encounter with the Milky Way?one it is unlikely to survive intact. This is, however, a contentious subject as astronomers are still debating the nature of the Canis Major dwarf galaxy itself.
