The Lagoon Nebula, also known as the Hourglass Nebula, is a bright
emission nebula which lies about 5,000 light years away in the
constellation Sagittarius. Within the Lagoon Nebula there are several
collapsing clouds of gas and dust where new stars are forming. The
brightest area is a region of very active star formation.
