Puppis A is a supernova remnant (SNR) about 10 light-years in diameter. The supernova 'occurred' (ie. would have been seen on earth) approximately 3700 years ago. Although it overlaps the Vela Supernova Remnant, it is four times more distant.

A hypervelocity neutron star known as the Cosmic Cannonball‎ has been found in this SNR traveling ~3 million miles per hour.

Puppis X-1 (Puppis A) was discovered by a Skylark flight in October 1971, viewed for 1 min with an accuracy ≥ 2 arcsec, probably at 1M 0821-426, with Puppis A (RA 08<sup>h</sup> 23<sup>m</sup> 08.16<sup>s</sup> Dec -42º 41' 41.40") as the likely visual counterpart.

Puppis A is one of the brightest X-ray sources in the X-ray sky. Its X-ray designation is 2U 0821-42.
