These are three Nebula found in Sagittarius, two of them the Nebula we have to remember for the constellation quiz - M8 (the Lagoon Nebula) and M20 (the Trifid). The Nebula in the upper right hand corner is NGC 6559 (who didn't make Messier's list. Poor baby.). This is a false color photo, with a color scheme apparently made common by the HUbble Telescope. The color scheme works for land based telescopes because it allows the astronomer to ignore urban light pollution. M8 is 30 light years LONG and about 5000 light years away. It's actually very pretty with the false color palete, a pretty blue, and is a star forming region.
