Scientists have found the most massive star ever discovered. "R136a1" is seven times hotter, hundreds of times more massive, and millions of times brighter than the sun.
Those behind the find say the star may once have weighed as much as 320 solar masses. It's burning itself off with such intensity that it shines at nearly 10 million times the luminosity of the sun.
UCSC astronomer Mark Krumholz is among those quoted in a Salon.com article about the finding.
