      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.
