Bizarre fast radio bursts detected from outer space.
They came from outer space.

More “fast radio bursts" — very short-lived pulses of radio waves that come from across the universe — have been detected by astronomers using two of the world’s largest telescopes.

The bursts, which come from a galaxy over 3 billion light-years from Earth, repeated 16 times. So far, these are the only known fast radio bursts that have repeated.

Fast radio bursts, which are highly energetic but last just a few thousandths of a second, have puzzled astrophysicists since their discovery just over a decade ago. Since 2007, several of these bursts have been recorded by telescopes around the world.
