Deep-space blasts came again and again and again
Fast radio bursts from deep space have never been seen to repeat — until now.
Ten blasts of radio waves recorded last May and June all come from the same direction, researchers report online March 2 in Nature. So did a signal detected in 2012, say Laura Spitler, an astrophysicist at the Max Planck Institute for Radio Astronomy in Bonn, Germany, and colleagues. All 11 signals were detected at the Arecibo Observatory in Puerto Rico.
