Messier 24 is an enormous cloud of stars lying in the Sagittarius arm of our galaxy, at a distance of about 10,000 light years from Earth. It is about 600 light years wide and occupies an area 90 arc minutes in apparent diameter. Among other objects, M24 contains the open cluster NGC 6603, which is at the center of this image. M24 is called the Small Sagittarius Star Cloud because there is another, larger star cloud south of it in Sagittarius, consisting of stars not obscured by the interstellar dust which blocks our view of the center of the galaxy.
