Description

This is a 2 panel mosaic of Simies 147, also known as the Spaghetti Nebula or Sharpless 2-240, a supernova remnant in the Milky Way straddling the border between the constellations Auriga and Taurus. Discovered in 1952 at the Crimean Astrophysical Observatory using a large 25" telescope, it is difficult to observe due to its extremely low brightness.
The nebulous area is fairly large with an almost spherical shell and filamentary structure. The remnant has a diameter of approximately 15 light years, covering 3 degrees of the sky, an area of roughly 6 full moons. It's estimated distance is 3000 (±350) light-years, and an age of approximately 40,000 years.
But the expanding remnant is not the only aftermath. The cosmic catastrophe also left behind in the nebula core a rapidly spinning neutron star known as pulsar PSR J0538+2817 emitting a strong radio signal, all that remains of the original star's core.
