(Pup A, SNR G260.4-03.4)
(supernova remnant bright in X-ray)

Puppis A (or Pup A) is a supernova remnant about 7000 light-years away for a supernova that would have become visible to Earth about 3700 years ago. It was discovered in 1971 as an X-ray source and is very bright in X-rays. Associated with it is RX J0822-4300, the supernova's neutron star remnant, which apparently was kicked, becoming a hypervelocity star.
