1. 
   supernova
   The death explosion of a massive star, resulting in a sharp increase in brightness followed by a gradual fading. At peak light output, supernova explosions can outshine a galaxy. The outer layers of the exploding star are blasted out in a radioactive cloud. This expanding cloud, visible long after the initial explosion fades from view, forms a supernova remnant .

The outer layers of the exploding star are blasted out in a radioactive cloud. This expanding cloud, visible long after the initial explosion fades from view, forms a supernova remnant (SNR).

   Supernova
   The outburst of a star on a tremendous scale. There are broadly 2 types of supernova. (1). Where a white dwarf member of a binary system explodes, or matter falls onto the white dwarf and explodes. (2). The collapse and then chaotic explosion of a single massive star.

    supernova
    supernova, a massive star in the latter stages of stellar evolution that suddenly contracts and then explodes, increasing its energy output as much as a billionfold.
