Mysterious ‘fast radio burst’ traced to a known object in the Milky Way for the first time ever

Fast radio bursts (FRBs) are some of the most energetic — and most brief — blasts of light in the universe.

These mysterious radio wave pulses flash through space a thousand times a day, occasionally brushing past Earth and its vigilant telescopes. FRBs appear and disappear in milliseconds, yet pack more energy than the sun unleashes in three days. Some FRBs repeat over days or months. Most travel hundreds of millions of light-years to reach Earth. And none have ever led back to a definitive source in the cosmos — until now.
