Astronomers detect biggest star

(BBC): They are among the true monsters of space – colossal stars whose size and brightness go well beyond what many scientists thought was even possible. One of the objects, known simply as R136a1, is the most massive ever found. The star is seen to have a mass about 265 times that of our own Sun; but the latest modelling work suggests at birth it could have been bigger, still. Perhaps as much as 320 times that of the Sun, says Professor Paul Crowther from Sheffield University, UK. "If it replaced the Sun in our Solar System, it would outshine [it] by as much as the Sun currently outshines the full Moon," the astronomer told BBC News.
