The Lagoon Nebula (also known as M8, NGC 6523 and Sharpless 25) is a giant interstellar cloud in the constellation Sagittarius. The Lagoon Nebula is one of only two star-forming nebulae faintly visible to the naked eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct oval cloudlike patch with a definite core. In the foreground is the open cluster NGC 6530. The Lagoon Nebula is estimated to be between 4,000-6,000 light-years away and 110 by 50 light years in size
