(CNN) — Fast radio bursts, or bright, millisecond-long flashes of radio waves in space, are one of the most enduring mysteries of the cosmos — and they just became a little stranger.
The first fast radio burst, or FRB, was discovered in 2007, and since then, hundreds of these quick, intense events have been detected coming from distant points across the universe. In a thousandth of a second, the bursts can generate as much energy as the sun creates in one year or more, according to previous research.
