Jouni Raunio, Tampereen Ursa

In the spring the weather was considerably better than in the autumn and I was able to describe both wideband and narrowband. This twin supernova remnant was described along the spring on four nights 28.2, 1.3, and 28-29.4. The exposure accumulated for a total of 9 hours.

      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.
