This huge ball of stars predates our Sun. Long before humankind evolved, before dinosaurs roamed, and even before our Earth existed, ancient globs of stars condensed and orbited a young Milky Way Galaxy.M3 contains about half a million stars, most of which are old and red. Light takes about 35,000 years to reach us from M3, which spans about 150 light years (APOD description).
