On Saturday, August 26th, astronomers reinvestigated a source that emitted a little-understood event: a fast radio burst (FRB).A small section of the Karl Jansky Very Large Array, one of the world’s largest and most powerful arrays of radio telescopes. Image credit: John Fowler.In 2012, a series of nine bursts were observed by both the Very Large Array and Arecibo, four of which were seen simultaneously. For the first time, this allowed us to pinpoint the location of a FRB’s source: a dwarf galaxy 3 billion light years away.The host galaxy of these fast radio bursts is a dwarf galaxy with an active galactic nucleus. The stars within it, on average, have far fewer heavy elements (and hence, rocky, potentially habitable planets) than the ones in our Milky Way.
