(Space.com) These Bizarre Deep-Space Radio Blasts Have Astronomers Baffled
A split-second burst of energy that erupted in deep space is giving astronomers important new clues about a mysterious class of astrophysical phenomena.
Only a handful of these rapid, millisecond-duration events, known as “fast radio bursts” (FRBs), had been detected previously, all of them by a single instrument — the Parkes Observatory in Australia. As a result, some astronomers have speculated that FRBs have local origins.
But the latest burst, which was observed on Nov. 2, 2012 by the Arecibo radio telescope in Puerto Rico, puts the lie to that notion, researchers said.
