Eta Carinae Nebula in Carina Constellation

Eta Carinae Nebula (NGC 3372) in Carina constellation is a large emission nebula that contains a number of O-type stars and several open star clusters. The brightest, most notable star in the nebula is eta Carinae, a supergiant 100 times as massive as the Sun, expected to explode as a supernova or hypernova in the relatively near future. Eta Carinae is one of the brightest and most massive stars in the Milky Way galaxy. It lies 7,500 – 8,000 light-years away.

The Carina Nebula is between 6,500 and 10,000 light-years distant from Earth.
