For the very first time, a cosmic Fast Radio Burst has been seen to repeat

% of readers think this story is Fact. Add your two cents.
A fast radio burst detected in 2012 has now been seen to repeat.
That’s big news. Every other FRB detected has been a one-off kind of thing: Now you see it, now you don’t. But FRB 121102 (named after the date it was first seen, Nov. 2, 2012) has been seen to repeat not just once, but 10 separate times. Whatever is causing it is a pretty eager attention hound.
The repetitions were seen using the Arecibo radio telescope in Puerto Rico over the course of 16 days. Some of the bursts were just minutes apart, but no obvious periodicity (like, one every 10 minutes) was seen over the 10 events …. http://www.slate.com
