'Coursework: Galaxies and Quasars'

'\n withal in antediluvian times, people sight the night turn over sh whiz band that stretches across the firmament pale. It looked corresponding they spilled milk. According to legend, this merit Hera, who came down to Earth. . light band c anyed the milklike stylus\n and then, lots later, through observations of Galileo, it was denote that the milky path - a stage set so outlying(prenominal) and pale stars. They will merge into one(a) dim glow. Then there was the hypothesis that the sun, all microscopical stars, including stars of the Milky Way belong to one huge form. . This brass is called the beetleweed\nGalaxy (in Greek quarrel - milk) - a bombastic star system consisting of stars, star clusters, spread and gaseous nebulae, open gas and spit.\n get along with of galaxies over 10 billion geezerhood. Depending on the size of the galaxy contains 100 billion stars. Galaxies atomic number 18 sight as shiny spots foggy round, oval or irregular shape. Th e social structure are trinity types of galaxies: spiral, elliptical and irregular, rarely are rings. Galaxies that are sources of radiation, known as galaxies. In these unquiet processes occur, accompanied by emission of matter.\nThe diagnose of our galaxy - the Milky Way (Milky Way). It consists of the sun and the solar system. genuinely long been make do about its size, exercising weight, twist of stars. Only recently, in the twentieth century, all kinds of research necessitate allowed a manyone to judge the completely thing. She imagines himself spyralnu galaxy as large track record with a jumper, diam approximately 30 kiloparsek (100 000 years of the world) and a thickness of 3,000 years of world. It has about 3? 1011 stars, and its total weight is about 6? 1011 solar masses.\nIn studying the incline with a telescope, draw off the stars showed themselves still unreadable foggy spots. Their so called - Nebula. Subsequently, it was found that the character by no means identical. virtually of them were clumps of gas and dust that includes our galaxy. Their can be found in the section of the nebula. closely hazopylovi clouds also take issue from each other. However, some of the nebula is strikingly distinguishable from the others ...'
