Mysterious ‘fast radio burst’ detected closer to Earth than ever before

Thirty thousand years ago, a dead star on the other side of the Milky Way belched out a powerful mixture of radio and X-ray energy. On April 28, 2020, that belch swept over Earth, triggering alarms at observatories around the world.

The signal was there and gone in half a second, but that’s all scientists needed to confirm they had detected something remarkable: the first ever “fast radio burst” (FRB) to emanate from a known star within the Milky Way, according to a study published July 27 in The Astrophysical Journal Letters.
