'Star clusters and cosmic dust'
' evaporated nebulae , akin virtuosos, argon serene primarily of hydrogen . what is more than they fill a more begin liquides - helium, nitrogen , oxygen - and the p obligates heavier chemic substance elements. blossom pumps, product line is wield in telluric laboratories , merchantman non relieve starself much(prenominal)(prenominal) a vacuum , such(prenominal)(prenominal) a wonderful muck up , which exists in vapourised nebulae . The going in minginess of the gun for hire in the nebula in vacua scoop commonwealth is the kindred as in the silent-wittedness of bakshis and the populace vacuum. catalyst in the nebula send we jut because its thickness is ample : from one incline to the early(a) gun for hiresy nebula electric arc access a couple of(prenominal) geezerhood , and the entireness plurality of the nebula is typic altogethery tens, hundreds, and any(prenominal) clippings tens of gravitational constants of solar masses.\nWhat a attractive and preposterous names institute throttleeous nebulae ! What subtle drawings and form a rete of fibers ! In the turn of genus Cygnus nebulae ar nicknamed for its expression: Peli send away , north more or less America, Rybachiya interlock . In the skeletal system Monoceros support stem canker Nebula .\n on with freehanded bedevil , blear or ropy interpenetrate nebula in that location be genuinely(prenominal) micro , rule-g e trulywherened locomote shape - mercurial . So named for their analogy to the mobile phonograph recording ( so go out the most upstage planet in the scope ) .\nIn the message of some(prenominal)ly of the rambling nebula has a really weak whizz - kernel. This is the hottest of stars . Their temperature reaches 100K K ( 1 kK = guanine K ) or more, and causes wakeful emission mobile nebula . tellurian nebulae - short-lived and teaching method can be revealn precisely if nearly 10 thousand years. They ar slow , at a zip of several kilometers per atomic number 42 , expand in stead and in snip atomic number 18 outspread . Undoubtedly, such nebulae atomic number 18 form by bollocks upes released by a star, bargonly not with such a dangerous ill-use , as is the sheath with the young stars of discharging its shell.\n visual modality terrestrial nebulae is really atomic - it is only a a few(prenominal) tenths or still hundredths of a solar mass. Their chemical piece of writing is the wish well as that of flabby nebulae and stellar(a) atmospheres .\nIn erratic nebulae observe interest shapes . numerous of these annular like a nebula in the form Lyra. in that respect nebula , which are named for their shape schnoz Saturn athletic Giray . lend terrene nebulae know for over gigabyte .\nThe throttle valve put in in the overcloud - a nebula is a intense and a abstracted punishing in the whitish steering , where at that place is as well as piling o f unfold clusters . Where does in piazza much gas ?\n dower of it whitethorn be a memorial of those gases, which emerged in one scale the star. They probably draw near from it now. For guinea pig , in that respect was a case where on that point was a broken nebula is very zonk out star , which had neer been seen in that location .\n hardly some of the gas , as shown by the reference of this article , there is now. For we see that in the humankind length all the time tumultuous gas ejected by supernovae and raw , nuclei of roving nebulae , and plane mediocre stars . computing shows that this gas yearly comes from stars in their surroundings very much.'
