The Lagoon Nebula is 8 in Charles Messier's "not a comet" list, 25 in the Sharpless catalog and 6523 in the New General Calalog.(NGC) It is a cloud of ionized hydrogen estimated to be 4000-6000 light years from earth. It can be seen with the naked eye as a gray/green patch in the constellation of Sagittarius..Almost in the center of the photo can be seen NGC 6530, an open cluster of young stars formed from material within the nebula. The entire nebula is roughly 110 x 50 light-years wide.
