How Stars Are Formed by Almir

Have you ever wanted to know how stars are formed? Do you even know what a star really is? Well, if you think that it’s just a hot ball of light, then you’re wrong. A star is a huge sphere of very hot glowing gas. Stars produce their own light and energy by a process called nuclear fusion. Fusion happens when lighter elements are forced to become heavier elements. When this happens a tremendous amount of energy is created causing the star to heat up and shine. Stars come in different color and sizes. Our sun is a medium sized yellowish star. Stars smaller than our sun is red and stars bigger than our sun are blue. When you’re outside at night and you look at those tiny stars, well there not as tiny as you think they are, most stars are bigger than our planet. If you don’t know how a star is formed, here are some facts on how they are formed.

 First, a cloud of gas and dust are disturbed by the gravity of a nearby explosion. The disturbance causes clumps to form and draw gas inwards. The clumps start to collapse, the collapsing clumps begin to rotate and flatten into a disk of gas and dust. The disk rotates faster and faster pulling more material inwards, creating a hot dense core called a protostar. When the protostar becomes hot enough, hydrogen atoms begin to fuse, producing helium and energy.

Hopefully you have learned a lot about stars.
