What happens during a supernova?
A
two nebulas collide
B
a massive star explodes
C
a new solar system forms
D
a sun emits a small burst of energy
Explanation: 

Detailed explanation-1: -This collapse produces the explosion we call a supernova. Supernovae are so powerful they create new atomic nuclei. As a massive star collapses, it produces a shockwave that can induce fusion reactions in the star’s outer shell. These fusion reactions create new atomic nuclei in a process called nucleosynthesis.

Detailed explanation-2: -Stars are so large that the gravitational forces holding them together are strong enough to keep the nuclear reactions from blowing them apart. It is the gravitational rebound that blows apart a star in a supernova.

Detailed explanation-3: -A supernova is an explosion of a massive supergiant star. It may shine with the brightness of 10 billion suns! The total energy output may be 1044 joules, as much as the total output of the sun during its 10 billion year lifetime.
