Today in the Journal Science it was announced that for only the second time the pinpoint location of a Fast Radio Burst (FRB) has been found, one of the most mysterious things in astronomy that probably require new physics to explain. This FRB came from the outskirts of a old massive galaxy with little new star formation which was very unlike the first the FRB which came from the center of a young dwarf galaxy with lots of stellar formation, and that indicates FRB's are a general phenomena not requiring unusual astronomical conditions.
Only about 60 FRB's have ever been observed, mostly in the last 5 years, but the location of only 2 have been found. They only last about a millisecond but produce as much energy as the sun does in 80 years and most never repeat so they're hard to detect much less precisely locate, but it's estimated that about 10,000 must happen every day in the observable universe. Theories have been proposed for their cause but all the ones I've heard involve very weird stuff of one sort or another.
