Stars

Today, I bore you all with my seventh grade paper on stars. In it, I discuss the life of stars, including the brilliant beginnings and endings:

Have you ever wondered what stars are like? What are they made of and how do they form? Many people have wondered this. One ancient philosopher of the Grecian age, named Anaxamines, believed Earth was flat like a tabletop and moisture rising from it created the stars. Today we know that stars are made up of pressure, gas, and dust. Stars are balls of gas. They are made of light, heat, and radiation. Stars come to being in a cloud called a ‘Nebulae.’ This nebulae is made up of gas and dust from the remains of other stars. Within the cloud, clumps of gas and dust form as the two break apart. The clumps will collapse from the weight of their own gravity. This pressure forms the clumps in the shape of a ball. Heat rises rapidly as the pressure intensifies. Once the temperature is up to somewhere around 18 million degrees Fahrenheit the ball ignites and burns the gases it was formed out of. A star has been born.

A star’s wavelength and amount of heat are what determines the color. This color will change as the stars grow older, from blue-white to red. Their heat has intensified greatly or decreased greatly. However, this color cannot be seen on a normal night. We only see white dots. The deaths of stars are much more dramatic than their birth. A star’s fuel eventually runs out and it swells in size. It begins to rid itself of outer layers. The gas and dust becomes a cloud, known as a planetary nebula. Small stars have long slow deaths at the end of which the core collapses. What is left is known as a “white dwarf.” It is one of the smallest stars in existence. Big stars, like the sun, end their lives with a bigger bang. Large stars burn their fuel faster than their smaller cousins can. While the star is burning, the outward pressure intensifies, similar to the white dwarf. This outer pressure is balanced by gravity, which also creates inner pressure. When the star’s life begins to end, the surface pressure decreases. The star then swells to become a red giant. The core shrinks from the pressure of gravity. The pressure is still burning, although its fuel has run out. In a second, the pressure reaches billions of degrees. The core collapses, releasing a shockwave that destroys the star. This explosion is so big that we can see it from Earth.

Supernova remains will eventually become a nebula, in which the process begins again. This star may also become a black hole Depending on the original  mass of the star, a black hole will form. All the matter shrinks to a tiny, dense mass. The pull of gravity is stronger than any other. This pull belongs to a new, black hole.

The life, death and science of stars is a fascinating thing. However, it should be noted that this theory is all based on conjecture. We have no proof of these happenings. Even so, this theory is intiguing. Many people have looked to the sky and many people will continue to do so. I hope after reading this paper, you’ll do the same.

  1. Why do you find this boring? Part of being a good writer, is taking a ‘mundane’ topic and making it interesting. I think you’ve done a fine job!
