Hey mate!

Supernovas is an astronomical term for a star that explodes like crazy. When a star turns into a supernova , it becomes extremely bright.


Supernova sounds like a superhero, but it refers to the super explosion of a star. A nova is also the explosion of a star, but a supernova has more energy. A supernova happens when a star becomes bright, bursts, and its matter is scattered in all directions, with light and radiation shooting out. Some say our sun will turn into a supernova someday, which would destroy all life on Earth.

Don’t worry, that’s a long way off.


Hope it's help you!

Answer 2

Here is your answer:

Supernova is a gigantic explosion of a star.

Supernova occurs when the star has no longer able to take its own energy.

$\bf{CAUSES}$

• Actually the Sun has so much energy that it continuously emits it. It changes helium to hydrogen by nuclear reactions.
• The supernova takes place when the Star has crossed its age. It is out of its nuclear fuel. Some of its mass eventually enters the core.The core cannot withstand so much mass.Hence pressure builds up. Supernovas take place.

$\bf{CONSEQUENCES}$

The supernovas release huge amount of energy into the Space.

It releases huge amount of powerful radiations including heat , Ultraviolet rays,Gamma rays.

$\bf{IMPORTANCE}$

Well the supernovae has a lot of significance

• They help in transporting energy throughout the Universe
• It emits lots of radiations which is distributed after an explosion

The Star after explosion may turn to a black hole.

But it is a very timetaking process takes trillions of years for a big star

But scientists say that there are supernovae taking place every second in the Universe

Then imagine how big and infinite our Universe is!

Hope it helps you
