Escaping Pulsar Breaks Speed Records - Universe Today
Astronomers have found a fast moving pulsar on a trajectory that'll take it completely out of the Milky Way. The object, called B1508+55, is located about 7,700 light-years from Earth. The incredibly sharp radio vision of the continent-wide Very Long Baseline Array (VLBA) has tracked this pulsar moving at approximately 1,100 km/s (670 miles/s). By tracking its position back, the astronomers have calculated that it started out in the constellation Cygnus. A powerful nearby supernova explosion probably kicked it into its current trajectory.
