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.

Scientists originally thought the signal -- sporadic bursts of radio  waves -- was coming from within the Milky Way itself, or from our  closest galactic neighbors, but a new report in the journal Nature confirms it emanates from a tiny galaxy 1% the mass of our own.  

 Cornell University researcher Shami Chatterjee said in a statement. 

 "These radio flashes must have enormous amounts of energy to be visible from over 3 billion light-years away,"
