What Are FRBs? The Discovery of Mysterious Signals From the Cosmos
The greatest mystery of modern radio astronomy comes down to just three letters: FRB. They stand for fast radio bursts, signals that continue to defy explanation. As the name implies, these bursts of radio waves last just a millisecond or two. They’re also incredibly strong, among the brightest radio sources in the sky. That’s despite traveling an incredible distance, up to billions of light-years. Do the math, and it’s clear how powerful these things are. One FRB can easily broadcast more energy in a moment than the sun produces in a day.
