Puppis A

Supernova remnant

Puppis A (Pup A) is a supernova remnant (SNR) about 100 light-years in diameter and roughly 6500–7000 light-years distant.[1] Its apparent angular diameter is about 1 degree.[2] The light of the supernova explosion reached Earth approximately 3700 years ago. Although it overlaps the Vela Supernova Remnant, it is four times more distant.

Quick Facts Event type, Date ...

A hypervelocity neutron star known as the Cosmic Cannonball has been found in this SNR.

Puppis X-1

Puppis X-1 (Puppis A) was discovered by a Skylark flight in October 1971, viewed for 1 min with an accuracy ≥ 2 arcsec,[3] probably at 1M 0821-426, with Puppis A (RA 08h 23m 08.16s Dec -42° 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.

  • Puppis A: X-ray [blue:0.3-8 keV] + IR [red-green:24-70 microns] (21 August 2014).
  • Puppis A: X-ray [blue:high]/[green:medium]/[red:low] (10 September 2014).
