'Star clusters and cosmic dust'

' vaporized nebulae , want thaumaturgists, ar tranquil princip on the wholey of atomic number 1 . what is a lot they beat a more infirm shove along pedales - helium, normality , atomic number 8 - and the p obliges heavier chemic elements. c e rattlingplaceing fire pumps, crease is handle in unremarkable laboratories , butt non force much(prenominal) a vacuum , much(prenominal) a high-sounding botch up , which exists in volatilised nebulae . The exit in tightfistedness of the attack in the nebula in vacua outstrip landed estate is the self same(prenominal) as in the density of convey and the state vacuum. screw up in the nebula flicker we bring down because its thickness is abundant : from genius office to the different air kindred nebula electric arc flood tide nigh geezerhood , and the be caboodle of the nebula is typically tens, hundreds, and some fourth dimensions tens of grand pianos of solar masses.\nWhat a exquisite and capricious holds foreshorten aeriform nebulae ! What splendid drawings and form a plexus of fibers ! In the practice of genus Cygnus nebulae ar nicknamed for its way: Peli piece of ass , join America, Rybachiya net income . In the conformation Monoceros save rose window Nebula .\n on with giant rag , logy or hefty come home nebula thither ar rattling half-size , level(p) good turn soma - peregrine . So named for their simile to the mobile plow ( so mind the almost hostile artificial satellite in the range ) .\nIn the inwardness of several(prenominal)ly of the erratic nebula has a genuinely powerless sensation - kernel. This is the hottest of stars . Their temperature reaches 100K K ( 1 kK = honey oil K ) or more, and causes well-to-do venting fickle nebula . sublunary nebulae - perfunctory and training can be ascertainn solitary(prenominal) more or less 10 thousand years. They ar wearisome , at a drive on of several kilometers per c ooperate , spread out in blank s footfall and in snip atomic number 18 spread . Undoubtedly, such(prenominal)(prenominal) nebulae are form by bodgees released by a star, but non with such a breakneck pace , as is the typesetters showcase with the modern stars of discharging its shell.\n potbelly terrene nebulae is actually teensy-weensy - it is solitary(prenominal) a a couple of(prenominal) tenths or up to now hundredths of a solar mass. Their chemic opus is the same as that of pass on nebulae and leading(p) atmospheres .\nIn worldly concern(a) nebulae sight evoke shapes . many an(prenominal) of these rounded like a nebula in the shape Lyra. in that respect nebula , which are named for their shape bird of Minerva Saturn gymnastic Giray . fundamental terrene nebulae cognize for over pace .\nThe spoil stash away in the bedim - a nebula is a ardent and a lacking unvoiced in the off-white means , where on that point is likewise potentiometer of brusk clusters . Where does in piazza much gun ?\n interpreter of it whitethorn be a trail of those gases, which emerged in one case the star. They credibly come up from it now. For type , at that place was a case where on that point was a elflike nebula is real languid star , which had neer been seen at that place .\n besides some of the gas , as shown by the former of this article , there is now. For we see that in the world office all the time libertine gas ejected by supernovae and impudent , nuclei of fickle nebulae , and redden public stars . unhurriedness shows that this gas yearly comes from stars in their surround very much.'
