The Lagoon Nebula is one of the largest star forming regions in our part of the Milky Way. It spans around 150 light years across and lies about 5,500 light years from us in the direction of the constellation Sagittarius on the next spiral arm inward from our own. Under dark skies, M8 appears as a faint smudge on the Milky Way but through a large telescope the nebula shows intricate detail in the densest regions.
