Crab Nebula originally to catalog all objects which could be confused with a comet 1054 A.D. Messier catalog radio Messier object 2U 0531+22 A chaotic, expanding mass of gas in Taurus, the remnant of a Type I supernova whose light reached Earth in 1054. It is an intense radio source, and its visible light is strongly polarized. It is also a source of X-rays and gamma-rays. Its total mass is about 1 M_sun, but the total energy radiated by the Crab is 10³⁷-10³⁸ ergs s^-1. It is periodically occulted by the Moon, and every June its radio spectrum is occulted by the solar corona. 2 kpc 947 years 1

Cygnus Loop radio source catalog X-ray X-ray source Cygnus X-5 A supernova remnant, consisting of a large loop of gas ejected from a star. It is 100 pc above the galactic plane. (X-ray observations give a distance of 2-3 kpc.) It is a thermal bremsstrahlung source of soft X-rays with a spectral temperature of 2 × 10⁶ K. 770 pc 20000 years

Monoceros Loop radio source catalog radio supernova remnant emission nebula A filamentary supernova remnant resembling a loop. 1 kpc 300000 years

Puppis A radio source catalog X-ray X-ray source 2U 0821-42 A supernova remnant. It is an extended nonthermal radio source, and also a source of soft X-rays. 1 to 2 kpc 10⁴ to 10⁵ years

Vela supernova remnant radio source catalog radio supernova remnant emission nebula A gaseous nebula in the middle of the Gum Nebula, the remnant of a Type II supernova whose light reached Earth about 10000 to 30000 years ago. It consists of bright filaments that form a D-shaped ring in Hα and a rough circle in the ultraviolet. It includes the Vela X, Y, and Z radio complexes and is a strong X-ray source.

W44 radio source catalog radio supernova remnant emission nebula A radio source. It is a supernova remnant less than 0°.5 from the galactic plane. 3 kpc

W51 radio source catalog radio supernova remnant emission nebula A radio source, a supernova remnant. PSR 1919+14 lies within its radio contours.
