The Carina Nebula, NGC 3372, is a star forming region located about 7,500 light years away in the Sagittarius-Carina Arm of the Milky Way. It is over 300 light years away, one of the largest star forming regions in our galaxy. Over 14,000 stars have been located within the region.
The region includes Trumpler 15, an area with a deficit of X-ray activity suggesting that some of the young, massive stars have already died in supernova explosions. Six possible neutron stars in the Carina Nebula support the hypothesis that supernova activity is increasing. The nebula also contains Eta Carinae, a variable star over 100 times the mass of our Sun.
