By now, you may have seen the incredible pictures of the Five-hundred-meter Aperture Spherical Radio Telescope or FAST, an enormous telescope in the Guizhou province of China that just turned on last year. You've also probably heard that, yes, many hope it will find signs of alien life. It's already beginning to make discoveries.

Fast radio bursts are split-second intergalactic blips of radio waves we've detected over the last decade. You'd think that if we pointed our telescopes and other space cameras in the direction these bursts came from, we'd spot something else, too. But to date, we have nothing -- just radio waves.
