Joseph Taylor and Russell Hulse used the signals from one of these objects to test Einstein's prediction of gravitational radiation.  As in the nearby example in Vela, they are formed when a supernova leaves a rapidly-spinning magnetic object which then produces regular bursts of radio emission at Earth.  For ten points, name this type of neutron star discovered in 1967 by Anthony Hewish and Jocelyn Bell.
