Keywords: simeis 147 giuseppe donatiello tim stone Sh2-240 / Simeis 147 / SNR G180.0-01.7 [Credit: Giuseppe Donatiello / Tim Stone] RA center: 84.727° DEC center: 27.813° Simeis 147, also known as the Spaghetti Nebula, SNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant (SNR) in Auriga and Taurus. Discovered in 1952 at the Crimean Astrophysical Observatory using a 25-inch Schmidt-Cassegrain telescope, it is difficult to observe due to its extremely low brightness. The remnant has an apparent diameter of approximately 3° (as six full moons), at 3000 (±350) light-years and an age of obout 40,000 years.
