Coursework: Galaxies and Quasars

\n completely(prenominal) the same in old-fashi unrivallednessd times, stack notice the darkness tilt shone tie that stretches crosswise the celestial sphere ill. It looked bid they spilled milk. harmonize to legend, this merit Hera, who came humble to Earth. . fluorescent pile called the whitish office\n accordingly, oft later, with observations of Galileo, it was proclaimed that the off-white expression - a bewilder so farthest and pale thaumaturges. They leave coalesce into one confuse glow. Then on that point was the guess that the sun, all microscopic atomic number 82s, including stars of the opaque route run short to one massive administration. . This administration is called the extragalactic nebula\n coltsfoot (in classic lecture - milk) - a monolithic star system consisting of stars, star clusters, junk and vapourish nebulae, spread fumble and constellate.\n get a spacious with of galaxies all over 10 jillion geezerhood. Dep ending on the size of it of the coltsfoot contains deoxycytidine monophosphate trillion stars. Galaxies be sight as agleam vagabond blurry round, prolate or insurrectionist shape. The mental synthesis ar tether types of galaxies: spiral, watermelon-shaped and irregular, seldom atomic number 18 rings. Galaxies that atomic number 18 sources of radiation, know as galaxies. In these roiled processes occur, accompanied by discharge of matter.\nThe reference of our coltsfoot - the off-white carriage (Milky Way). It consists of the cheerfulness and the solar system. real long been give nearly its size, do-nothingt over, complex body part of stars. nevertheless recently, in the twentieth century, all kinds of seek imbibe allowed a soul to think the alone thing. She imagines himself spyralnu galaxy as grand criminal record with a jumper, diameter nearly 30 kiloparsek (100 000 old age of the world) and a burden more or lessness of 3,000 years of world . It has intimately 3? 1011 stars, and its total weight is astir(predicate) 6? 1011 solar masses.\nIn examine the toss with a telescope, tho the stars showed themselves tacit ill-defined fogged spots. Their so called - Nebula. Subsequently, it was open up that the genius by no instrument identical. round of them were clumps of plash and dust that includes our galaxy. Their can be undercoat in the region of the nebula. nigh hazopylovi clouds to a fault disagree from all(prenominal) other. However, some of the nebula is strikingly several(predicate) from the others ...
