In earlier times people understood the sun to be the most terrifying thing in space. This sun was the limitation of the thinking of the people of the previous era. People used to think that the brightness of the sun so far away was so great that even the earth thousands of kilometers away bowed its head to it. Later, as science progressed, people came to know about the sun.

Then people saw that not only the sun is the biggest star, people have identified many stars much bigger than the sun. To whom we think the omnipotent sun is nothing. Then as science progressed, people could learn more about the stars. People see that the sun is made of gas. The sun gets its power and light through nuclear fusion of hydrogen and helium.

Man then gradually divides the stars into one class.
In this way man is defeated by himself. People saw that all the terrible things in space were Nova. No object is permanent in nature, the one who is born will be destroyed, just as the stars that explode when they die are called Nova by scientists.
Scientists divide this Nova into parts such as type1 supernova, type2 supernova, Kilonova, Hypernova. Let's get to know each other these Nova shots.
Type 1 supernova: -
When a binary star system has a white dwarf and an ordinary start, then when that ordinary star becomes a red giant, it will continue to absorb the particles in the white draft. In this way, at a time when the amount is too much, the white dwarf star will make a blast called Type 1 supernova.
Type 2 supernova: -
When a star ends its life phase, when it runs out of all its gases, there will be no nucleus fusion due to which the force on the outside will no longer be applied and the forces of gravity will increase so that the balance and imbalance of that star will occur. Due to gravity forces the particles outside will go inside and explode which is called Type 2 supernova.
It is much stronger than type 1.

This time Gamma-Ray-Burst is emitted, and if this Gamma-Ray-Burst falls on a planet, life will be destroyed from that planet in a few minutes. If we had this kind of supernova 25 light years away from Earth, it would destroy all the creatures on Earth. If this supernova is 1000 light years away from us then we will be saved.
And every 100 years there are 2 supernova in our galaxy. And during supernova 10²² jul of energy is generated.
Hypernova: -
Much more powerful and much more than a supernova. During this Hypernova so much energy is generated that the sun cannot produce this energy for the rest of its life. Its brilliance is so great that even if a star is formed by a few million suns together, Hypernova will have very little.
When the life cycle of a star 30 times larger than the sun is over, the nucleus fusion will stop due to lack of fuel. Then there will be imbalance of that star and the pair will make a blasts.
However, Hypernova is much less likely to notice 1 in our Galaxy every 100 years. And for safety from this we have to stay at least 10000 light years away from Hypernova.
Kilonova: -
Kilonova is the explosion that occurs when two space monsters, the black hole and the neutronstar, meet. But not as strong as Hypernova. But it emits Gamma-Ray-Burst for a few moments.
