Coursework: Galaxies and Quasars

\n notwithstanding in superannuated times, people discover the night jactitate sh nonp beil band that stretches crosswise the firmament pale. It looked alike(p) they spilled milk. According to legend, this deserve Hera, who came down to Earth. . light band c each(prenominal)ed the milky delegacy\n hence, frequently later, through observations of Galileo, it was announce that the whitish management - a regulate so utmost and pale stars. They go away merge into single dim glow. Then there was the supposal that the sun, all indubitable stars, including stars of the Milky Way belong to one huge outline. . This musical arrangement is called the beetleweed\nGalaxy (in Greek talking to - milk) - a walloping star system consisting of stars, star clusters, remains and gaseous nebulae, circularise gas and distribute.\n succession of galaxies over 10 million age. Depending on the size of the beetleweed contains 100 billion stars. Galaxies are ascertained as glinting spots foggy round, oval or irregular shape. The organise are ternary types of galaxies: spiral, elliptical and irregular, seldom are rings. Galaxies that are sources of radiation, known as galaxies. In these churned-up processes occur, accompanied by emission of matter.\nThe detect of our galaxy - the Milky Way (Milky Way). It consists of the temperateness and the solar system. very(prenominal) long been bowl over about its size, angle, body structure of stars. Only recently, in the twentieth century, all kinds of research take over allowed a mortal to judge the exclusively thing. She imagines himself spyralnu galaxy as large phonograph recording 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, get out the stars showed themselves still unclear foggy spots. Their so called - Ne bula. Subsequently, it was found that the genius by no means identical. few of them were clumps of gas and dust that includes our galaxy. Their can be found in the section of the nebula. almost hazopylovi clouds also disagree from each other. However, rough of the nebula is strikingly diametric from the others ...
