Astronomers caught a potent radio burst blasting at us from a dwarf galaxy 3 billion light-years...

Now, astronomers are accruing the evidence they need to put the pieces of the FRB puzzle together—a newly spotted burst has two key attributes that might help astronomers take a more sustained look at these enigmatic explosions.
The latest FRB detection comes from the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Guizhou, China. But this explosion was more than just one flash in astronomers’ data. It repeats at regular intervals, so researchers were able to locate it in follow-up observations at telescopes around the world. Described in a paper published in the journal Nature this week, FRB 20190520B is also associated with a persistent source of radio emissions between those bursts. The source sits at the edge of a dwarf galaxy roughly 3 billion light-years from Earth.
