    Astronomers have detected one of the brightest supernova ever seen and surmised that the star that exploded may have been 150 times the mass of the Sun. The exploding star, 240 million light years away in galaxy NGC 1260, swiftly became the object of scrutiny by the orbiting Chandra X-ray Telescope as well as a number of ground-based telescopes. Before the explosion, the star ejected a great deal of mass. Scientists have seen this behavior in another star - Eta Carinae, in our own Milky Way Galaxy.
