Eta Carina Nebula
(Key-hole Nebula), NGC 3372
This is one of the most impressive objects in the sky of any type. It is a southern object in the constellation of Carina that spans about 2 degrees. The red glowing gas clouds are split by huge dark lanes giving the appearance of a starfish. The Eta Carina star which illuminates the nebula is an unstable blue supergiant a million times more luminous than our sun.
