_________________________________________________________
Simeis 147, also known as the Spaghetti Nebula, SNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant straddling the border between Auriga and Taurus. This is very difficult to observe due to its extremely low brightness.
The remnant has an apparent diameter of approximately 3+ degrees, an estimated distance of approximately 3000 light-years, and an age of approximately 40,000 years.
