Astronomers have detected an “activity cycle” behind massive radio pulses emanating from a galaxy billions of light years away, shedding light on one of the great cosmic mysteries, which some suggest could be a sign of alien life.

Known as fast radio bursts (FRBs), the flashes of emissions were first noticed in 2007 and appear to originate from galaxies light-years away from Earth, but exactly what causes them still has scientists scratching their heads. The bursts are immensely powerful, giving off as much energy in the space of a few milliseconds as Earth’s sun does in a whole century.

While more than 100 FRBs have been observed since their discovery, most of them have been a one-off phenomenon, giving off only a single burst. But more recently, scientists have found that a small number of FRBs repeat, noticing regular patterns or “activity cycles” behind the enigmatic flashes.
