Nearly 500 million light years away, a mysterious radio signal is repeating itself. It’s a new piece in the puzzle of fast radio bursts (FRBs) — short bursts of radio waves that are so powerful that scientists are able to detect them on Earth, despite their extragalactic origins. Fast radio bursts are hard to study because of how brief they are, meaning telescopes can’t often focus on them in time to get a good look. Hence, the new discovery of a fast radio burst that repeats once every 16 days is a major clue, and marks the first time scientists have documented a predictable pattern among these mysterious repeating signals that are originating deep in space. read more https://www.rawstory.com/2020/02/sc...epeating-radio-signal-from-outside-milky-way/
