M61

Constellation: Virgo
NGC 4303
Galaxy
This is a spiral galaxy in among the Virgo cluster.  It is one of the larger galaxies some 100,000 light-years in diameter.  Astronomers think it is approx 60 million light-years away from us.  (It still amazes me to think that we can see something that far away, ok, ok, so it is pretty good size- still.)  Our star man, Messier, it is said mistook this galaxy for a comet.  M61 visual magnitude is 9.7 making it pretty dim so a large telescope is needed to really get a detailed image of this bad boy.  NASA has a good Pick of the day of M61
