Petri Kuossari, Riihimäen tähtit. yhdistys

In the morning I photographed comet C / 2021 A1 Leonard and in the evening it was M1 crab fog. The bigger picture also shows the small planet 857 Glass Button. From this I made my own observation to the star of the sky.

      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.
