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.

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.

Fast radio bursts (FRBs) are one of the greater mysteries facing astronomers today, rivaled only by gravitational waves (GWs) and gamma-ray bursts (GRBs). Originally discovered in 2007 by American astronomer Duncan Lorimer (for whom the "Lorimer Burst" is named),

Fresh research has indicated that astronomers have discovered fast radio bursts (FRBs) emanating from a far-distant ‘dead’ galaxy

Instead of finding the radio burst in a region of young stars, researchers traced its origin to the outskirts of a “dead” elliptical galaxy.

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.

Astronomers have observed over a thousand of them to date; some come from sources that repeatedly emit FRBs, while others seem to burst once and go silent. You can produce this sort of sudden surge of energy by destroying something.

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.

For the first time, astronomers have traced a fast radio burst (FRB) to the outskirts of an ancient, dead, elliptical galaxy—an unprecedented home for a phenomenon previously associated with much younger galaxies.
