Either from the edge of the universe, or the microwave in the staff common room

Arecibo Observatory Detects Mysterious, Energetic Radio Burst – Phenomena

(I'm not serious about the microwave being the problem, but the way.)

I don't remember reading about these extremely brief bursts of radio waves (apparently) from the far flung corners of the universe before, so it's an interesting read.  I see that one had been caught at Parkes radio telescope, too.  Why didn't they tell me that when I was visiting there at Christmas?
