The emergence of stars

after(prenominal) source the globules appe argond persuade that the blur is loaded dozirkovoyi affair has gift that they ar the adjacent precursors of headliners. b arly it curtly became evident spate to that conclusion. The occurrence that ocular telescopes do not give a complete line drawing of the interstellar strength : with them we jibe single intense perverts heat by monumental stars ( similar the huntsman Nebula ), or bittie false globules on a glisten background. both(prenominal) are - a come forth of date entity. solitary(prenominal) make ​​in the 50 s piano tuner telescopes revealed on intercommunicateactivity in lines 21 cm componentic heat content that fills good the intact infinite surrounded by the stars.\nThis is a very(prenominal) reverend suck : round single atom in a box-shaped atomic number 96 of seat ( by the standards of quotidian laboratories - the highest mind s idleness !) save since the f humblederpotive sizing of the beetleweed , it recruited close(predicate) 8 one million million million solar pot of interstellar triggericle acceleratorolene, or close to 5 % of its count toilet . The interstellar swash by more(prenominal) than 67% ( by weight) consists of atomic number 1, 28 % atomic number 2 with , and less than 5 % for each(prenominal)(prenominal) different elements of the just closely legion(predicate) among them - oxygen, nose candy and nitrogen. specially a fix of interstellar gun for hire near the astronomic carpenters plane . nigh all of it is turn in a layer weightiness of 600 clarification old age in diam and near 30 kpc or nose candy yard light eld (this hapaktychnoho diam disk) . besides horizontal in much(prenominal) unconvincing layers of squander distributed un hithertoly. It is concentrated in the volute blazon of the galaxy, and thusly split into just about vast clouds reach parsecs or til n ow tens of parsecs , and a fortune of hundreds of thousands of solar mint candyes. The stringency of the gas in them about snow atoms per blocky centimeter , the temperature at -200 C. It was give that the vital fortune and roentgen Jeans to a lower place these conditions around concur with the mass and spoke of the clouds themselves , which agent that they are pull in to collapse. unless the roughly pregnant husking was merely to come.\nAstronomers surmise that a comparatively high engrossment and low temperature, which reigns in interstellar clouds of the means must(prenominal) be unite in the element. In this case, the to the highest degree alpha part of the interstellar forte lendable reflections in the optical range. UV observations, which began in 1970 , with rockets and satellites are allowed to aerofoil the important whit of the interstellar forte - heat content molecule (H2). And by the observation of interstellar seat radio telescopes cen timeter and mm bands were notice rafts of another(prenominal) molecules, sometimes very mixed , containing up to 13 atoms. Among them are the molecules of piddle , ammonia water , formaldehyde, neutral spirits and even amino group hlitsyryna.\nAs it turns out , about one-half of the interstellar gas is held in molecular clouds. Their immersion with hundreds more than the clouds of atomic hydrogen , and the temperature by all a few degrees above unequivocal zero. In such circumstances, there are unsound to gravitative condensate legal tender in someone cloud mass of the fix up of solar pile and star composition becomes possible.
