For more than a decade, astronomers across the globe have wrestled with the perplexities of fast radio bursts — intense, unexplained cosmic flashes of energy, light years away, that pop for mere milliseconds.

Despite the hundreds of records of these enigmatic sources, researchers have only pinpointed the precise location of four such bursts.

Now there’s a fifth, detected by a team of international scientists that includes West Virginia University researchers. The finding, which relied on eight telescopes spanning locations from the United Kingdom to China, was published today (Monday, January 6, 2020) in Nature.

There are two primary types of fast radio bursts, explained Kshitij Aggarwal, a physics graduate student at WVU and a co-author of the paper: repeaters, which flash multiple times, and non-repeaters, one-off events. This observation marks only the second time scientists have determined the location of a repeating fast radio burst.
