GENERAL KNOWLEDGE

Detailed explanation-1: -A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the last stage in the life of massive stars that are at least eight times larger than our Sun. As these stars burn the fuel in their cores, they produce heat.

Detailed explanation-2: -Stars do explode, and when that happens they’re known as supernovae. A supernova creates an explosion billions of times brighter than our sun, with enough energy to outshine its own galaxy for weeks. These massive explosions throw large amounts of matter out into space.

Detailed explanation-3: -Supermassive stars are extreme versions of so-called Population III stars, the first stars that formed in the universe (Fig. 1).

Detailed explanation-4: -A supernova is the explosion of a star. It is the largest explosion that takes place in space. Where Do Supernovas Take Place? Supernovas are often seen in other galaxies. But supernovas are difficult to see in our own Milky Way galaxy because dust blocks our view.
