  Supernova remnant is the remnant of the big star died in supernova explosion. The supernova remnants are quite irregularly shaped. Rather many of them ring-like strusture.
  
  The moderate big instruments and possibly special filters are needed to see supernova remnants.
  
  The Crab Nebula was born in a star explosion in 1054. This is the easiest supernova remnant in the sky to observe. Image Tero Hirvikoski.
  
  The supernova remnant Simesis 147 is in Taurs and Auriga. Image J-P Metsävainio.
  
  The Veil Nebula in Cygnus is wide-area supernova remnant in the sky. There is a detailed image of the boxed area. Image J-P Metsävainio.
  
  This detail of Veil Nebula is known as Pickering's Triangle. Image J-P metsävainio.
