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

Astronomers have discovered fast-repeating radio signals coming from a distant "dead" galaxy. This is an unusual find since "dead" galaxies are not expected to have the energy needed to produce these signals,
