Supernova – UPSC Prelims

What is Supernova?
  • Supernovae(SNe) are highly energetic explosions in the Universe releasing an enormous amount of energy.
  • Long-term monitoring of these explosions helps us understand the nature of the exploding star as well as the explosion properties. It can also help calculate the number of massive stars.
  • A supernova is the explosion of a star. It is the largest explosion that takes place in space. Supernovas are often seen in other galaxies. But supernovas are difficult to see in our own Milky Way galaxy because dust blocks our view. Further, a supernova happens where there is a change in the core or center of a star.
