Astronomers Traced a Mysterious Radio Burst to a Distant Galaxy

Astronomers traced a mysterious, fleeting radio burst from space back to the galaxy from which it originated for the first time.

Cosmic Sleuthing
Astronomers who detected a mysterious, fleeting radio signal from space finally figured out where it came from.

The radio burst, which only lasted for one millisecond, originated from the outer reaches of a distant galaxy, from which it spent 4 billion years traveling to Earth. In this case, astronomers at Chile’s Gemini South telescope were able to track the radio signal’s origins using a finely-tuned array of antennas, according to research published in the journal Science. The scientists think their approach could help pinpoint other signals from outer space.
