About this Image

The Eta Carina Nebula (NGC3372) is a large bright nebula that has within its boundaries several related open clusters of stars. Bright Eta Carinae at the lower center is a highly luminous hypergiant star. Estimates of its mass range from 100 to 150 times the mass of the Sun, and its luminosity is about four million times that of the Sun. Eta Carinae's effects on the nebula can be seen directly, eroding the dusty and glowing areas nearby. In the center of the image the famous keyhole Nebula can be seen in detail.
