Name: Lagoon Nebula - M8

The Lagoon Nebula is estimated to be between 4,000-6,000 light years  from the Earth. In the sky of Earth, it spans 90' by 40', translates to an actual dimension of 110 by 50 light years. Like many nebulas, it appears pink in time-exposure colour photos but is gray to the eye peering through binoculars or a telescope, human vision having poor colour sensitivity at low light levels. The nebula contains a number of Bok globules - dark, collapsing clouds of protostellar material - the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296.
