Clear FRB (IMAGE)
Caption
Astronomers detected a persistent radio signal from a far-off galaxy that appears to flash with surprising regularity. Named FRB 20191221A, this fast radio burst, or FRB, is currently the longest-lasting FRB, with the clearest periodic pattern, detected to date. Pictured is the large radio telescope CHIME that picked up the FRB.
