Glenn's Astrophotography




M33 is a spiral galaxy also much like our own Milky Way and is in the constellation of Triangulum. At a distance of about 2.5 Million light years from Earth, it is our second nearest neighboring major galaxy and is also part of our local group of galaxies. The bluish color of this galaxy is due to the large number of young, hot stars in its arms.
