The radio burst was detected on May 15, 2014 by astronomers in Australia but just reported in the Monthly Notices of the Royal Astronomical Society, Fox News reported. “The burst was identified within 10 seconds of its occurrence,” said Emily Petroff, a PhD student at Melbourne’s Swinburne University of Technology, according to Fox News. “The importance of the discovery was recognized very quickly and we were all working very excitedly to contact other astronomers and telescopes around the world to look at the location of the burst,” she added. Scientists have long used equipment to search for radio signals, hoping to find signs of extraterrestrial life. The bursts, which emit as much energy in a few milliseconds as the sun does in 24 hours, have been detected before, Petroff told Fox News. And, while they were just detected here on Earth, the bursts actually took place a long time ago. More
