​​ stars By:Tyler and Bradley



All stars start at a swirling cloud of gas and dust. With the force of gravity pulling the material in, it is forced in to roatate around the center. Under immense pressure and ​ heat from the particles bumping together, nuclear fusion starts. Atoms are spun so fast they fuse together on impact with each other, they begin to glow and a star is formed.

A star ranges from 1/2 to 20 times the size of our sun, and can be different colors depending on the temperature:


 * ** Temperature ** ||= ** color ** ||
 * ** Under 3,500 K ** ||= red ||
 * ** 3,500 – 5,000 K ** ||= orange to red ||
 * ** 5,000 – 6,000 K ** ||= white you yellow ||
 * ** 6,000 - 7,500 K ** ||= blue to white ||
 * ** 7,500 - 11,000 K ** ||= blue ||
 * ** 11,000 - 25,000 K ** ||= blue ||
 * ** 25,000 K and up ** ||= blue ||

The star begins to glow brightly, it is now a main sequence star, at this stage is where average stars and massive stars cycle differences begin. This newly formed star is like all things and is under forces gravity pulling it inward. For millions of years this large star burns using hydrogen, for smaller stars they can last for billions of years before they run out of fuel. once these stars begin to run out of fuel, The gravitational pull of the planet and outward force of the burin hydrogen are even as long as the star still has fuel to burn. As soon as one overpowers the other the entire system goes down.

When the fuel starts to run out the forces of gravity push in on the planet, the high pressure and heat make the star expand up to a hundred times larger, it is now a red giant. Depending on the stars size it will either do two things; the sun sized stars exterior expands while the interior comes inward. The exterior begins to shed itself off and create a planetary nebula and become a white dwarf where it slowly shrinks and cools off, For larger stars the end is much faster.

After the red giant phase, larger stars that are at least 5 times bigger than our Sun, start the beginning of the end. The iron in the planet sinks to the core, the planet is no longer able to contunue to create fusion and the star goes boom!!!!!! The star explodes in a supernova, some of the particles join together with other nebulas to create new stars. The core of the star can still remain as a neutron star, where the electrons and protons are forced together to form neutrons. but more likely the immense force from the collapse the neutrons will not survive and the star will become a black hole.
