A mysterious signal that has confounded scientists for years has been traced to a spot in the sky more than 3 billion light-years away. Almost a decade after the first fast radio burst (FRB) was discovered, an international team of researchers has pinpointed the origin of one such signal as a dwarf galaxy in the pentagon-shaped constellation Auriga.

"These radio flashes must have enormous amounts of energy to be visible from over 3 billion light-years away," Cornell University researcher Shami Chatterjee said in a statement. Ultra-rare galaxy could be 'one of a kind' Visible-light image of the dwarf galaxy from which signal FRB121102 is emanating. Distant signals Fast radio bursts were first discover...
