Description

Simeis 147, also known as the Spaghetti NebulaSNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Aurigaand Taurus. Discovered in 1952 at the Crimean Astrophysical Observatory by Grigory Shajn and his team using a Schmidt camera and a narrowband filter that was close to the Hydrogen Alpha transmission line. It is difficult to observe due to its extremely low brightness. This discovery was part of a survey conducted between 1945 and 1955 most likely using captured German equipment, as the observatory was practically destroyed during WWII. The Schmidt camera had a field of view of 175'. Many previously unknown hydrogen nebula were discovered this way, which did not appear in regular photographs. The nebulous area is fairly large with an almost spherical shell and filamentary structure. The remnant has an apparent diameter of approximately 3 degrees, an estimated distance of approximately 3000 (±350) light-years, and an age of approximately 40,000 yearsIt is believed that after its stellar explosion a rapidly spinning neutron star known as pulsarPSR J0538+2817 was left behind in the nebula core, emitting a strong radio signal.
