Mysterious radio signal from space with 'heartbeat' pattern detected
A mysterious radio explosion with a pattern similar to a heartbeat has been detected in space. Astronomers estimate that the signal came from a galaxy about a billion light years away, but the exact location and cause of the explosion is unknown. A study detailing the findings published Wednesday in the journal Natural . Rapid radio bursts, or FRBs, are intense, millisecond-long bursts of radio waves of unknown origin. The first FRBs were discovered in 2007, and since then, hundreds of these rapid cosmic flashes have been detected coming from various distant points throughout the universe.

Fast radio bursts are so fast and unpredictable that they are difficult to observe. One of the sources used to find them is a radio telescope called th...
