Eta Carinae: A Star On the Brink of Destruction

Eta Carinae has a mass of approximately 150 times that of the sun, and is about 4 million times brighter than our local star, making it one of the most massive and most luminous stars known. The red outer glow surrounding the star is composed of the very fastest moving of the material which was ejected during the last century's outburst, much of which is moving more than two million miles per hour.
The knots of ejected material have sizes comparable to that of our solar system.
