The Milky Way Galaxy is surrounded by a “halo” of “globular”
star clusters, like this one: Messier 2 (M2) in the
constellation Aquarius. This one lies about 37,500
light years from our Solar System, is about 175 light years
across, and contains about 150,000 stars. It was discovered
by Jean-Dominique Maraldi in 1746. |
