A wide-field composite view of the supernova remnant Puppis A (X-rays from ROSAT in purple, optical data in pink) puts the motion of the neutron star RX J0822-4300 into context. The explosion that created the supernova may have been lop-sided, kicking the neutron star in one direction and much of the debris in the other. Astronomers calculate that RX J0822-4300 is moving at about 3 million miles per hour, making it one of the fastest moving stars ever observed.
