Full Press Release

Binary System with orbits Neutron star (pulsar) and white dwarf rotating around each other in close binary orbits. The pulsar's orbit is marked in purple and the white dwarf's in red. Orbital traces on the plane of the sky change over time (i.e. orbital precession) as predicted by Einstein's theory of gravity.
