Simeis 147, also known as SNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant (SNR) located between "the horns" of Taurus in the Auriga-Toro border region.
Discovered in 1952 at the Crimean Astrophysical Observatory by Grigory Shajn and his team, using a 25-inch Schmidt-Cassegrain telescope equipped with an H-alpha filter, this SNR is difficult to observe visually due to its extremely low luminosity [Catalogue of HII Regions (Sharpless 1959)]. Even photographically it is a difficult subject, although less than in the past.
The rest is in fact about 3° in apparent diameter (like six full moons), at a distance of 3000 (±350) light years and an age of about 40,000 years [AstrophysJ., Suppl. Ser., Vol. 49, p. 183-206 (1982)].
Inside is the pulsar PSR J0538+2817 with an age consistent with the age of the SNR [Astrophys.J. 654: 487-493, (2006)].
