Mysterious Radio Blasts From Space Just Got a Whole Lot Weirder, Somehow

Scientists discovered that so-called “giant radio pulses” coincide with X-rays, suggesting they are hundreds of times more energetic than previously thought.

In the year 1054, skywatchers in China and Japan witnessed light from an exploding star reach Earth, creating a dazzling bright spot in the sky. More than a millennium later, scientists have now revealed amazing new details about the powerful and unexplained radio signals that eerily emanate from the remains of this ancient supernova.

For years, scientists have been baffled by extremely loud radio signals, known as giant radio pulses (GRPs), that can be traced to a special type of dead star known as a pulsar. Pulsars are compact, rapidly rotating remnants of supernovae that get their name from the clockwork pulses of radiation they emit from their poles, which have made them useful natural timepieces for astronomers who use their regular bursts to measure other celestial phenomena.
