Rotating RAdio Transients (RRATs) are one of the newest things in radio astronomy. According to Sky and Telescope magazine, a team of astronomers analyzing data from the Parkes Radio Telescope have seen a number of neutron stars that have emitted sporadic but powerful radio bursts. RRATs (pdf) have spin properties that resemble magnetars. The Square Kilometer Array (SKA) could help find many new RRATs.
