Astronomers have traced the signal of an enigmatic repeating fast radio burst for only the second time.
According to CNN, its source is located in a spiral galaxy similar to Earth's, not so far away.
Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space.
Individual radio bursts emit once and don't repeat.
Repeating fast radio bursts are known to send out short energetic radio waves multiple times.
