Astronomers discover likely source of strange radio bursts from space

Article Link:

For more than 13 years, astronomers have been trying to determine the source of extremely powerful radio bursts that can travel billions of kilometres through space but only last a fraction of a second. These signals — called fast radio bursts (FRBs) — were discovered in 2007 by two astrophysicists while poring through data collected in 2001 from the Parkes Observatory in New South Wales, Australia. Since then, dozens more have been detected, even a different form called repeating fast radio bursts. But just what is responsible for pumping out these extremely bright radio signals has remained shrouded in mystery, with even the odd whisper of whether or not it was astrophysical in the first place. Until now.
