How Star birth?


Stars have been forming throughout the universe for most of its life. That take shape in vast clouds where thousands of stars are born at time.
The clouds give birth to the stars are cold and dense and consists mainly of hydrogen gas. The newly formed stars are huge spinning globes of hot, glowing guess mainly hydrogen, with helium and small amount of other elements to stop much of this material is a packed tightly on to the stars cores, and it is here that nuclear reaction release energy in the form of heat and light.

How new star form

the star forming process begins in the cloud becomes understandable and breaks up on two fragments. Gravity pulls the material in a fragment on to and never trigger club and the club slowly form a spear it shrinks. Now protostars, star to be carried on shrinking, it cores getting the denser and hotter.eventually the pressure and temperature are so high that nuclear reaction begin, and the stars start to shine

1. Interstellar cloud


Stars are born within enormous, cold, dense cloud of gas and dust. The process of stars formation may be triggered if something disturb the cloud, such as a collision with another clouds or a shock wave from a supernova explosion.




2. Fragment form


Now unstable cloud breaks up into fragment of different size and mass. The most massive and size dance of this pregnant gradually pulled by their own gravity into tighter clumps full stop this shrinking fragment will eventually turn into protostar.




3. Protostar


A protostar forms. Gravity pulls material into it core, where the density, pressure, temperature build up. The more matter the original cloud fragment contained, greater temperature and pressure rise as the protector develops.




4. Spinning disc


The growing mass at the center creates a gravitational pull, drawing evermore gas and dust inwards.A bit like water going down a plughole, the material being pulled in stars to spin around. Powerful winds blowing jets of gas out from the center.


5. Star is born


Squeezed by the force of gravity, protostar core  become so hot and dense that nuclear reaction occurs, and the star begins to shine. The glowing core produce and outward pressure that balance the inward poles of gravity,making the star stable. It is now a main sequence star.



6. planets form


not all the material from the gas cloud has been used to make the star stop the left over form spinning disc of gas and dust around the star. The debris may be lost into space, or it may clubbed together to form planets, moons, comet and asteroid


Fact
The brightest star in 6 million times more  light then the sun


Star birth nebula


clouds of gas and dust in space are called nebulous. Match of the gas and dust in a nebula is debris from old star that exploded when they ran out of fuel. Over millions of the years, the material is recycled to make new stars. Star but nebulous are among the most beautiful object in a space, there colorful clouds illuminated from within by the blue light of newborn stars.

Orion nebula
the Orion nebula is one of the closest star forming region on earth. In the night sky it looks like a Fuzzy star in the sword of Orion full stop in reality, it is a vast cloud of gas and dust thousands of time bigger than the solar system.


Star cluster

Star are not form singly they are born in a cluster from the same clouds on material at roughly the same time. Eventually, the stars of the cluster will drift apart and exist alone in a space, with a clothes companion or two. Our sun, like about half of the stars nearest to us, is alone. About a third of the stars in the night sky are in pairs, bound together by gravity
