A fast radio burst, or a strong pulse of energy, was tracked to a distant long-dead galaxy that astronomers never thought could produce such a signal.

Unusual detection bolsters evidence that the mysterious signals can be caused by different astrophysical events.

Astronomers have traced two mysterious fast radio bursts from space to wildly different places, which suggests the phenomenon may originate in diverse ways.

Researchers Intrigued by Mysterious Fast Radio Burst Originating From Ancient Galaxy Researchers have been observing fast radio bursts in space for years and continue to be intrigued by them because of the huge energy they release.

Astronomer Calvin Leung was excited last summer to crunch data from a newly commissioned radio telescope to precisely pinpoint the origin of repeated bursts of intense radio waves—so-called fast radio bursts (FRBs)—emanating from somewhere in the northern constellation Ursa Minor.
