Astronomy Essay -- essays research papers

uranology Astronomy is not just somewhat the brilliances. Astronomy is ab place the constellations, the nine planets, the sun and the moons. The solar system is very confused and has m whatsoever extraordinary objects. There are four different types of stars Protostars, coruscant principal sums, Red Giants, and White Dwarfs. Protostars are stars that are on the verge of macrocosm born. They are refulgency clouds of dust and artillery. Gravity pulls on every mote moving them towards the center of the cloud of dust, which causes the Protostar to collapse. Over a period of xx cardinal geezerhood the star begins to form and 10 million age after the pocket of gas was formed, a star is born. The second types of stars are called Bright Stars. They are formed when the new star has completed about 35 million years of its life cycle. A stars life cycle is a lot like a servicemans life cycle, except a stars years are in millions. When a star is about 10 million years old it is in the same stage on average as a regular human that is about twenty years old. The birth and death rate of stars is called Stellar Evolution. A Bright Star is made when nuclear fusion doubles the size of the star. The third types of stars are called Red Giants. They are made because the outward flow of the stars core energy stops. Gravity then steps in and squeezes the star to make it decrease in size. The core of the stars disturb increases and it starts releasing small amounts of energy, the energy holds a vainglorious amount of atomic number 1 gas. The star then begins to grow larger, but it does not get knowinger. As a result of the sudden and fast temperature drop, the stars colourise changes from blue-white to a red color. Most Red Giant stars have been nominate in groups called Globular Clusters. Globular Clusters are groups of up to one million stars that move through space. The fourth type of stars are called White Dwarfs. When a White Dwarf is made the star begins cooling off. As a result of cooling, the outer gas layer spreads out. The stars temperature drops and makes the gas layer spread out even more. Eventually, the outer layer spreads out so far that the gas layer separates from the star. Then, a Planetary Nebula (cloud of glowing atoms), moves in all directions. The stars core isnt with child(p) out any more energy and is to the point of collapsing slowly. All of the outlet that the star had in the beginning is still there, but it ... ...on. Orion was an past Greek hunter and warrior. The constellation Orion shows him caring a indian lodge shield, and a sword dangling from his belt. Orion has more Bright Stars the any other constellations. The two brightest stars in it are Betelgeuse and Rigel. Betelgeuse is Orions shoulder joint and Rigel is his foot. Cassiopeia is another well-known constellation. Cassiopeia is a group of stars, the brightest which form a large W in the northern sky. (Miller, 10). Cassiopeia is found next to th e Big roly-poly and Orion. Its shape is an exact M or W, formed with the five bright stars. The mythic Cassiopeia was an Ethiopian Queen. (Miller 10). Constellations are probably the most interesting intimacy in the solar system. Most people look at them as an exciting look at the mythological part of our solar system, and others animadvert that they are just another interesting part of the night sky. The population is something no one can explain. Our Galaxy is one of the countless galaxies continue throughout the Universe, like islands in a big ocean. Many objects in the Solar System have yet to be discovered and whitethorn never be, but it will always be there and whitethorn never change for generations to come.
