Hubble Spies Globular Cluster in Neighboring Galaxy
The Hubble telescope has captured a view of a globular cluster called G1, a large, bright ball of light in the center of the photograph.
G1, also known as Mayall II, orbits the Andromeda galaxy (M31), the nearest major spiral galaxy to our Milky Way. Located 130,000 light-years from Andromeda's center, G1 is the brightest globular cluster in the Local Group of galaxies, containing at least 300,000 old stars. The Local Group consists of about 20 nearby galaxies, including the Milky Way.
