From the mountains of British Columbia comes news of powerful bursts of radio energy from deep space. Astronomers estimate that thousands of these enigmatic lights scintillate across the sky, but they’re so fast and random it’s hard to know where to point a telescope to capture one. Called fast radio bursts or FRBs, they last only a millisecond or two, about as long the light in a typical photo flash. If our eyes could detect radio waves, the sky would pop like cameras at a presidential press conference.
