Into 2010 with M101


Big, beautiful spiral galaxy M101 is one of the last entries in Charles Messier's famous catalog. About 170,000 light-years across, this galaxy is huge, almost twice the size of our own Milky Way Galaxy.

M101 lies within the boundaries of the northern constellation Ursa Major, about 25 million light-years away.
