Back in 2011 and 2012, astronomers working at an Australian observatory picked up a series of fleeting but powerful radio signals. These signals have never been detected elsewhere, casting doubts on their origin. But now, new observations from the Arecibo Observatory in Puerto Rico suggest they're for real.
Late last week we told you about those unexplained — but extremely powerful — radio bursts that originated from another galaxy. A number of theories have been proposed to account for the phenomenon, but there’s one in particular that caught our attention: Blitzars — the final stage of a supramassive neutron star.
