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 detected fast-repeating radio bursts from a distant "dead" galaxy that should not contain the energy to produce these types of signals.

Scientists from Northwestern University and McGill University have made a discovery that challenges existing theories about the origins of fast radio bursts (FRBs). The findings, published in the Astrophysical Journal Letters detail the observation of a fast radio burst originating from an ancient,
