| Description | (adapted from Don Goldman) NGC 3199 (RCW 48) is a bright, 20’ crescent-shaped nebula in the constellation of Carina about 12,000 light years distant. Deeper images show the bright crescent to be part of a larger elliptical bubble. It is referred to as a ring nebula and is associated with a galactic Wolf-Rayet star (HD 89358), which is not at the center of the bubble. This could suggest that the WR star has moved since the nebula was formed. It resides in a diffuse HII region as shown by the faint background nebulosity. |
