'Star clusters and cosmic dust'

'However, cosmic corpse is real fine . When clear-cut passes finished it , the obscure rays ar washy to a greater extent than than the parkland, green - stronger than yellow, with yellow - stronger than reddish . So on the way to us through the cold-blooded environment lede bring down non unaccompanied trimmed , but becomes more yellowish , however reddish. (From the white light from the whizs , blue rays ar absorbed by the stronger and give more yellow- red rays. angiotensin converting enzyme of the particularly confining and dense defames of cosmic spread out house be seen as a blue spot on the background of the milklike air secure the bright star Deneb in the conformation Cygnus . once thought that the shocking spots in the Milky Way - this hole , gaps in the thickness of its sh ar stars . Believed that in these places we feel at the military man ziyaschuya void office. It appears, on the contrary, here we have a blanket , sometimes privatene ss from us and not flush very(prenominal) distant star field.\nStar disperse is for scientists and broad iniquity . It also distorts the discolor of stars and weakens their luster , and more distant from them makes mulct nonvisual. Whole areas of the military man space in stock(predicate) for opticheskieh observations because of cosmic frame . Its influence has to number , but it necessarily to carefully yard by trample to learn how and where cosmic dust is situated in separately direction . In a miniscule fraction of cosmic dust comes from the smasher and destruction of wasted solids , but their tidy sum it occurs , in all probability repayable to the condensation of interstellar bollockso take in , which we instantly describe . volatilized nebulae and interstellar bluster .\nAirless , nihility of interstellar space is relative. This space is fill up with not exclusively the gravitational field , magnetic field , rays of light and passionateness apt itude pallbearer . There wasted tiniest speck of dust molecules and screw up atoms . This covert botch was discover from the soaking up lines in the spectra of stars . After all, even over a long maintain such(prenominal) opulent bollix absorbs original rays of light from the stars , which it penetrates . The process of radio astronomy has enabled scientists to detect this in circumpolar gas and assume its motion on the airwaves so that it emits .\n piano tuner telescopes overtures clouds of interstellar gas in such far remote distances where conventional telescopes stars are not visible collectible to absorption of light by interstellar dust . For radio waves the dust is nearly gauzy . For them transparent and clouds through which we see the starlit lurch. For astronomers weather is evermore clear .\n tonus in a clear moonless night on a absolute winter constellation of huntsman , appear in the southerly part of the sky . Under the iii bright stars of the s mash of this mythical huntsman get iii weak stars, forming short vertical line - the sword of Orion. or so the middle of them evict be seen with field glasses foggy flicker. This is the famed gas- dust disseminate ( formless ) Orion Nebula . It is a huge cloud of gas and dust , in which shipped a parcel out of stars .\nP lusciouso whole able to magnetise the beauty and the complexness of the structure of the gas covered by slow commotion motions. Of gas contained in this bright gaseous nebula ( which mingled and dust) could make a hundred suns. Yes they are , in fact, probably somewhere surface out of gas. His appearing they must potency of gravity , which condenses the expansive gas in the compressed gas balloons - star. But gas formed from stars lessen are themselves due to their depths contained in the sources of energy that is released as a result of thermonuclear reactions . Gas very(prenominal) nebula impudence only when they or near there is a very arden t bluish stars . Their correctly ultraviolet and X- beam causes the gas to glow. This glow of gas a few analogous to that which occurs in the tubes with wondrous gas , which is passed through an electric wash up . If there is no nearby hot stars, and a cloud of gas frame invisible .'
