This immense ball of half a million stars older than the Sun lies over 30,000 light-years away. It is one of about 150 globular star clusters that roam the halo of our  Milky Way Galaxy. Individual stars are difficult to distinguished in the densely packed core, but colors are apparent for the bright stars on the cluster's outskirts. M3's many cool "red" giant stars take on a yellowish cast, while hotter giants and pulsating variable stars look light blue.
