Astrology, Our World, Our Adventure :: essays research papers fc
(Insert Name) (Insert Class) (Insert Date Due)                     Astrology, Our World, Our Adventure†¦      Astrology, and the wonders of the solar system†¦ Astrology is not just about the stars; it’s about the stars, constellations, the nine planets, meteors and asteroids, the sun, moons, and the constellations. The solar system is very complex, yet it has many extraordinary objects.      There are four different types of stars: Protostars, Bright Stars, Red Giants, and White Dwarfs. Protostars are stars that are just in the verge of being born. They are glowing clouds of interstellar dust and gas. Causing the protostar to collapse, gravity pulls on every atom moving them towards the center. Over a period of twenty million years the star begins to form, and in 10 million years after the pocket of gas formed, a star is born. The second types of stars, Bright Stars, are formed when the new star has completed about 35 million years of its life cycle. A star’s life cycle is a lot like a human’s, except a star’s years are in millions. When a star is about 10 million years old, it is in the same stage as a regular human-for instance in 10 million years a star is in the same stage as a human that is about twenty. The birth and death of stars are also called Stellar Evolution. A Bright star occurs when nuclear fusion doubles the star i n size. The third types of stars, Red Giants, are made because the outward flow of the star’s core energy stops. Gravity then steps in, squeezing the star making it decrease in size. The core’s heat increases and it starts releasing small amounts of energy, the energy holds a large amount of hydrogen gas. The star then begins to grow larger, but it does not get brighter. As a result of the sudden and quick temperature-drop, the star’s color changes from blue-white to a red. In groups called Globular Clusters (groups of up to one million stars that move through space), are where most of the Red Giants have been found. In the fourth types of stars, White Dwarfs, the star begins cooling off; and as a result of that, the outer gas layer spreads out. The star’s temperature drops again, making the gas layer spread out even more. Eventually, the outer layer spreads out so far, it separates from the star. Then, a Planetary Nebula (cloud of glowing atoms), moves i n all directions.
