Fast radio bursts are instantaneous radio flashes from deep space. In a thousandth of a second they release as much energy as the Sun emits in a month. One such burst, repeating, allowed scientists to peer into the epicenter of a recent stellar explosion.

Somewhere deep in space, a radio beacon flashes for a fraction of a second, and then goes dark. Such signals are called fast radio bursts. They come from other galaxies and last from microseconds to milliseconds.
