Description:

The Omega Nebula also known as the Swan Nebula, Checkmark Nebula, Lobster Nebula, and the Horseshoe Nebula is a star formation area. It is a small star cluster consisting of about 35 bright stars which are dimmed by the nebula in which they seem to be embedded. The nebula is containing a large amount of dark and darkening matter, a fact that  is reveald by the remarkable properties of M17. The mass of the gas is estimated to be 800 times higher than the mass of the sun. This is enough to form a well noticable cluster and its way more than the mass of M42, the Orion Nebula. Whilst the bright nebula appears  to have an extent of about 15 light years the whole gas cloud  including the faint matter extends to at least 40 light years. The distance to this object is about 5,000 to 6,000 light years.
