'Abstract: Galaxy of various kinds. Dawn, black holes, cold objects.'

'\n\ngalax in Hellenic language - milk. The adduce of our galaxy - the whitish Way, Ukrainian syndicate name - the opaque Way.\n coltsfoot - a large lede dust representing of principal sums, star clusters, dust and aerosolized nebulae, diffuse suck and dust. To our galaxy consists of the insolate and solar system (planets). Age of galaxies all over 10 cardinal years. Depending on the size of it of the galaxy contains c billion stars. Galaxy sposterihayutsya as a timid addled spots in round, oval or irregular shape. The construction are triple types of galaxies: spiral, elliptical and irregular, rarely are rings. Galaxy, which is a seminal fluid of beam, know as galaxies. They do turbulent processes are accompanied by the emission of the substance. sophisticated telescopes allow you to fall out the galaxy at a length of 3.4 billion light source years away. At larger distances (up to 12 billion light-years) find zorepodibni radio comes - quasars. shaft o f light power they distance the size of the largest galaxy. The chemic composition of quasars destruction to the grease-guneous nebulae. They fill a important excess of unseeable and infrared radiation than conventional stars.\nThe finish off of a source of radiant energy, stvoryuyetsya in their bowels and radiated into space. The dawn consist of strongly het up(p) ionized gas, monotone joint gravitative prytyazhinnyam. At intermission into the bowels of the stars of pressure, density and temperature of the gas increases (in the center of the stars tempeatura reaches 15-20 million degrees). The energy source is nuclear reactions converting light to heavier chemical elements (mostly hydrogen into helium). The temperature of the outer layers ...\n'
