      A supernova is the biggest explosion that humans have ever seen. It is the extremely bright, super-powerful explosion of a star.

This is a star

      A star is the balance between two opposite forces. The star’s gravity tries to condensate its mass. But the star’s core burns and creates pressure in the opposite direction.

 

This is a supernova (= a big star explosion)

      When a star runs out of fuel, it cools off. The star collapses  quickly. The enormous shock waves cause the outer part of the star to explode. Kaboom!

 

This is a nebula

      After the explosion, a beautiful cloud of hot gas forms. It’s called nebula.
