A massive exploding faraway star — the brightest supernova astronomers have ever seen — has scientists wondering if a similar celestial fireworks show may light up the sky much closer to Earth sometime soon.
The discovery, announced Monday by NASA, drew oohs and aahs for months from the handful of astronomers who peered through telescopes to see the fuzzy remnants of the spectacular explosion after it was first spotted last fall.
Using a variety of Earth and space telescopes, astronomers found a giant exploding star that they figure has shined about five times brighter than any of the hundreds of supernovae ever seen before, said discovery team leader Nathan Smith of the University of California at Berkeley. The discovery was first made last September by a graduate student in Texas.
"This one is way above anything else," Smith told The Associated Press. "It's really astonishing."
