Astronomers detect mysterious 8 billion-year-old energetic burst
Astronomers have detected an intense flash of radio waves coming from what looks like a merger of galaxies dating to about 8 billion years ago - the oldest-known instance of a phenomenon called a fast radio burst that continues to defy explanation. This burst in less than a millisecond unleashed the amount of energy our sun emits in three decades, researchers said. It was detected using the Australian SKA Pathfinder, a radio telescope in the state of Western Australia.
