Star ★
How A Star is Born :
Stars are glowing gas that is formed by nebulae. The huge clouds of dust and gas collapse under gravitational force forming protostars.The Stars are differ in size,mass,Temperature and Diameter ranging . Like earth stars also produce the greater gravity force when the core is bigger and hotter.The color of the star is determined by its temperature where Hottest stars are Blue and coldest Star are red. Stars live for less than a million year before exploding as a Supernova Explosion .
Nuclear Fusion :

Nuclear Fusion :
The Brightness of the star is measured by the Magnitude.Stars produce light and heat by nuclear fusion. The hydrogen atoms crash or bond the core it forms helium as releasing energy. Once the Temperature reaches 15,000,000 degrees celisius now the nuclear fusion is takes place in centre of the core or the centre of the cloud .In the core of a Star nuclear fusion converts hydrogen atom into helium atoms through multi stage process to complete this process two hydrogen atoms merged together into deuterium atom and by this process of fusion it froms Helium,Carbon,Neon,Oxygen,Silicon and Iron.
Types of Star :
*Small Star
*Medium star
*Massive or Giant Star
*Small Star
*Medium star
*Massive or Giant Star
Small Star :
In Small stars when hydrogen runs out the stars light slowly fadesThen it starts to shrink then it becomes dim finally it is exhausted and star becomes a black dwarf.

Medium Star:
When star like Sun has used up the hydrogen in its core it makes the star to grow as a red giant star but when it runs out of hydrogen and helium core as planetry Nebula the material exploded in this will rethe outer layers drift away from the core as a gas shell called Planetry Nebula and the core part is white Star .But while red giant star growing it may also swallow the nearby planet .
Sun is a example of Medium Star .

Massive or Giant Star:
These type of stars are 8 times bigger than the Sun.But in giant or massive stars the heat in the core is massive that nuclear fusion can not only fuse hydrogen atoms to form helium it can fuse helium to create carbon or oxygen when it forms as red giant star then the stars core fusion will spread around the star itself it results in changing the appearance of the star as Massive stars starts to shrink themselves over billion times smaller due to gravity force and they collapse themselves and became black hole
Supernova Explosion :
This a explosive death of a Star and often results in the star obtaining the brightness of a 100 million suns for a short time .This explosion lead to the Neutron star or Black Hole .
Neutron Star:
Neutron star produced when the supernova explosion occurs by forcing the protons and electrons to combine to produce a Neutron star. The Neutron stars are very dense.

Black Hole:
The gravity force in the Black hole is greater as if anything falls inside the black hole it is crushed by gravity into an infinite density. Even fastest source light cannot escape from the black hole

If two stars colloids each other it forms a black hole or massive neutron star this type of collision is called stellar collision.After a black hole is formed it can continue to grow by absorbing the mass in the surroundings. Absorbing other stars and merging with other black Hole
