This is a list of observed supernova remnants (SNRs) in the Milky Way, ... Spaghetti Nebula 05 h 39 m +27° 50′ ~40,000 years ago: 6.5: 3,000? neutron star PSR ...
SN 1054 remnant (Crab Nebula).. A supernova remnant (SNR) is the structure resulting from the explosion of a star in a supernova.The supernova remnant is bounded by an expanding shock wave, and consists of ejected material expanding from the explosion, and the interstellar material it sweeps up and shocks along the way.
Before 2013, the only plausible conventional supernova remnant in the old historical area for the supernova was the supernova remnant 3C 58. This remnant has a radio and X-ray pulsar that rotates about 15 times per second. So historically, SN 1181 had been associated with 3C 58 and its pulsar, although many researchers noted that this ...
CTB 1, also known as G116.9+00.1 and AJG 110, [1] nicknamed the Medulla Nebula, [2] is a supernova remnant located in the constellation Cassiopeia. It was discovered as a radio source in 1960 in a study of galactic radiation carried out at a frequency of 960 MHz. [3]

IRAS 00500+6713 is the catalogued infrared source for an unusual nebula in Cassiopeia, while the central star has a designation WD J005311, with the whole system designated as Pa 30. The central star and its surrounding shell were created by the supernova seen in the year 1181 ( SN 1181 ) as reported by Chinese and Japanese observers. [ 4 ]
RCW 103 is a supernova remnant with right ascension 16 h 17 m 30 s and declination −51° 02 ′. It is approximately 2000 years old and contains x-ray source 1E 161348-5055 at its heart. It is 10,000 light years away in the constellation Norma (constellation) .
[9] Mankind survived when the radiation from the Crab Nebula supernova, at a distance of about 6,500 light-years, reached Earth in the year 1054. A type Ia supernova at a distance of 3,300 light-years would have an apparent magnitude of around -9.3, about as bright as the brightest Iridium (satellite) flares. [10]
