Decades in the making, NASA's X-ray timelapse shows a stellar explosion expanding into space at up to 2% the speed of light.
Several telescopes used to observe the supernova SN Zwicky which was magnified nearly 25 times by a foreground galaxy acting ...
Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.
