THE TWINKLING STARS : UNSCATHED WARRIORS

I Belief Myself As A Star, 

I Have My Own Light,

Either Dimmer From Others,

Or Brighter From Others.

STARS-(GIANT WARRIORS) 

STARS are the giant luminous balls of gas helped the ancient explorers navigate the sea and now help modern day Scientist to navigate the Universe.

Gently singing Twinkle, twinkle, little star may calm a baby to sleep, but beyond the confines of Earth’s atmosphere, the words aren’t exactly accurate. 

Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat. Aside from our sun, the dots of light we see in the sky are all light-years from Earth. They are the building blocks of galaxies, of which there are billions in the universe. It’s impossible to know how many stars exist, but astronomers estimate that in our Milky Way galaxy alone, there are about more than 300 billion stars.

Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy. Moreover, stars are responsible for the manufacture and distribution of heavy elements such as carbon, nitrogen, and oxygen, and their characteristics are intimately tied to the characteristics of the planetary systems that may bind as Star System.

The observable Universe contains an estimated 1×10²⁴ [1,000,000,000,000,000,000,000,000] stars, but most are invisible to the naked eye from Earth.

BIRTH OF A STAR

Stars are born within the Giant clouds of dust [Cosmic Clouds] and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. As the cloud collapses, the material at the center begins to heat up. Known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. Three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the Milky Way are paired or in groups of multiple stars.

As the cloud collapses, a dense, hot core forms and begins gathering dust and gas. Not all of this dust material ends up as part of a star — the remaining dust can become planets, asteroids, or comets or may remain as dust.

During Most of life the life of normal star, over many billions of years, it will support itself it's own gravity by Thermal Pressure, caused by nuclear process which convert hydrogen into helium.

NASA describes stars rather like pressure-cookers. The explosive force of the nuclear fission inside them creates outward pressure which is constrained by gravity pulling everything inwards. 

DEATH OF A STAR

Eventually, however, the star will exhaust it's nuclear fuel.Paradoxically, the more fuel of the stars off with, the sooner it runs out.This is because the more massive the star is, the hotter it needs to balance it's gravitational attraction.

Most stars take millions of years to die. When a star runs out of fuel, it starts to cool off and so to contract. When the star becomes small, the matter particle get very near each other, after puffing off its outer layers, the star collapses to form a very dense white dwarf. One teaspoon of material from a white dwarf would weigh up to 100 tonnes. Over billions of years, the white dwarf cools and becomes invisible.

Stars heavier than eight times the mass of the Sun end their lives very suddenly. When they run out of fuel, they swell into red supergiants. They try to keep alive by burning different fuels, but this only works for a few million years. Then they blow themselves apart in a huge supernova explosion.

For a week or so, the supernova outshines all of the other stars in its galaxy. Then it quickly fades. All that is left is a tiny, dense object – a neutron star or a black hole – surrounded by an expanding cloud of very hot gas.

The elements made inside the supergiant (such as oxygen, carbon and iron) are scattered through space. This stardust eventually makes other stars and planets.
