M 33 is a member of the "local group" of galaxies. With good eyesight
and exceptionally dark skies, it can be seen with the naked eye, and
appears more than twice the size of the full moon. In reality, M 33 is 50,000
light years across, about half the size of our Milky Way galaxy. It is in the
constellation Triangulum, and is quite close to us, as galaxies go, about
3 million light years away (and, unlike most galaxies, M 33 is getting close
to the Milky Way, by about 15 miles each second). In this classic spiral galaxy,
you can see several nebulae in its arms, in which new stars will form.
