Astronomers find most powerful supernova

Astronomer Robert Quimby has again found the most luminous supernova. Quimby discovered the current record holder, supernova 2006gy, last year as part of his Texas Supernova Search project. Now he has announced that a supernova he has discovered earlier in the project is actually twice as luminous. Using follow-up studies to pinpoint its distance, supernova 2005ap peaked at more than 100 billion times the brightness of the Sun.
