Mysterious burst of radio waves traced to galaxy billions of light-years away

For the first time, a mysterious blast of energy known as a Fast Radio Burst (FRB) has been precisely traced to a distant galaxy, bringing scientists even closer to figuring out the origins of these odd cosmic flashes.

On April 18, 2015, a telescope caught sight of the FRB, and mere hours later, other telescopes found its location, tracing the source of the burst to a galaxy about 6 billion light-years away, according to a new study published in the journal Nature this week.

This marks the first time the distance to an FRB has been measured.

FRBs send out as much energy in a fraction of a second as the sun puts out in 10,000 years, but they are exceedingly difficult to find.
