Puppis A
(Pup A, SNR G260.4-03.4)
(supernova remnant bright in X-ray)
Puppis A (or Pup A) is a supernova remnant (SNR) about
7000 light-years away for a supernova that would have become visible
to Earth about 3700 years ago.
In the sky it overlaps the Vela supernova remnant, which is nearer.
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.
