Scientists honed in on the galaxy where mysterious fast radio bursts (FRB) seem to be originating. In just a few milliseconds, FRBs give off roughly the same amount of energy as the Sun does in a day, according to a New York Times report.

Why it matters: At least 30 FRBs have been found since 2007, per the Times, and scientists don't know what causes them. But, they've gotten more information about the environment around them after tracing a particularly repetitive burster called FRB121102 to a galaxy that's 3 billion light years away.
