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.
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) .
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]
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 ...
The basis for this was that 3C 58 was the only supernova remnant known in the large old historical region for the SN 1181. However, multiple factors, including the age (3500 to 5500 years) and energetics of the remnant, all point to 3C 58 as not being the remnant of SN 1181.
RX J0852.0−4622 (also known as G266.2−1.2) is a supernova remnant. The remnant is located in the southern sky in the constellation Vela ("sail"), and sits (in projection) inside the much larger and older Vela Supernova Remnant. For this reason, RX J0852.0−4622 is often referred to as Vela Junior (Vela Jr.).
