Izinkanyezi - izindikimba zasezulwini zikhanya ngokwabo

Astronomy - isayensi okhuluma ekutadisheni izinto ezingcwele. Uyazicabangela izinkanyezi, lezinkanyezi ezinomsila, amaplanethi, imithala akusho singayinaki imihlola ekhona, okwenzeka ngaphandle emkhathini woMhlaba, ezifana cosmic ngemisebe.

Ukutadisha ukufunda izinkanyezi, singathola impendulo yombuzo othi "imizimba yasezulwini zikhanya ngokwabo. Kuyini lokhu? ".

Izidumbu sonozungezilanga

Ukuze uthole ukuthi zikhona zasemkhathini zikhanya ngokwabo, okokuqala udinga ukuba uqonde ezinye zezindima zasezulwini kuyinto zesimiso sonozungezilanga.

Solar System - uhlelo kwamaplanethi, igxile inkanyezi - ilanga, nasemaceleni 8 amaplanethi: Mercury, Venus, uMhlaba, Mars, Jupiter, Saturn, i-Uranus, Neptune. Ukuze nendikimba ethile esemkhathini ngokuthi iplanethi, kumele ihlangabezane nalezi zimfuneko ezilandelayo:

• Ingabe imilenze ukujikeleza emhlabeni inkanyezi.
• Thatha uhlobo indilinga, bangakunaki gravity okwanele.
• Have emhlabeni wo orbit ezinye izidumbu ezinkulu.
• Ungabi inkanyezi.

Amaplanethi bungakhiphi ukukhanya, bayazibuza nje libonise asehlele kubo imisebe yelanga. Ngakho-ke ngeke sikwazi ukusho ukuthi iplanethi - kungcono izindikimba zasezulwini zikhanya ngokwabo. Lezi izinto ezisemkhathini izinkanyezi.

Sun - ungumthombo wokukhanya Emhlabeni

izindikimba zasezulwini zikhanya ngokwabo - izinkanyezi. inkanyezi eliseduze Earth - ilanga. Ngenxa ukukhanya kwayo futhi ukushisa, zonke ekuphileni kungaba khona nokuthuthukisa. Kunendawo eqondile ilanga maphakathi azungeze okuyinto amaplanethi, izinyanga, asteroyidi, lezinkanyezi ezinomsila, emkhathini nothuli cosmic.

Ilanga kubonakala eqinile eyindilinga, ngoba uma ubuka it, wabuka nazo okubonakala acace impela. Nokho, it has a isakhiwo esiqinile futhi yakhiwa amagesi esiyinhloko phakathi kuyo i-hydrogen ukhona, kanye nezinye izakhi.

Ukuze ubone ukuthi Sun ayinakho wabuka ecacile, kubalulekile ukubheka ngayo kuthiwa ukusitheka kwelanga. Khona-ke uzophawula ukuthi uzungeze imvelo ukushayela, okuyinto izikhathi eziningana mkhulu kunezinhliziyo ubukhulu bayo. Ngo kukhanya avamile halo ayibonakali ngenxa ekukhanyeni okukhazimulayo. Ngakho, ilanga alinaso imingcele eqondile futhi agcinwe isimo gaseous.

inkanyezi

Isibalo izinkanyezi ezikhona ayaziwa, ukuthi akuphi kude kakhulu eMhlabeni futhi ibonakala njengoba amachashazi ezincane. Izinkanyezi - nendikimba ethile esemkhathini ezikhazimulayo ngokwakho. Kusho ukuthini lokhu?

Izinkanyezi - elikhazimulayo sphere sakhiwa igesi, okuyinto zenzeka ukusabela iArmagedoni. ezindaweni zawo babe kwabantu ezahlukene kanye lokushisa. Usayizi izinkanyezi futhi ihluke nomunye ngenkathi they are amaplanethi xaxa futhi okukhulu ngaphezulu. Kunezinkanyezi ukuthi makhulu kunosayizi kwelanga, futhi lapho, futhi okuphambene nalokho.

It yakhiwa igesi, ngokwezinga elikhulu - hydrogen. On ubuso bayo, by lokushisa eliphezulu, i-molecule ye-hydrogen Ihlukana athomu amabili. I-athomu siqukethe proton ne-electron. Nokho Atoms ngaphansi kwethonya okushisa aphezulu "ukukhululwa" electron zabo, kuphumele igesi, okuthiwa - plasma. Atom, asele ngaphandle koxhumano electron, ngokuthi amantongomane.

Uma liqhathaniswa nezinye izinkanyezi akhipha ukukhanya

Star, ngenxa amandla elanga adonsela phansi, ezama cindezela ngokwayo ngokwayo, okuholela ingxenye emaphakathi thereof is kakhulu lokushisa likhuphuka. Ziqala ukwenzeka ukusabela zenuzi, okuphumela ekwakhiweni ane-helium ne-core entsha, esakhiwa proton emibili neutrons ezimbili. Ngenxa yalokho, ukwakheka nucleus entsha, semali amandla ikhishwe. Izinhlayiyana-izinhlayiyana eziningi zokukhanya ivelele njengoba amandla ngokweqile - nabo baphathe ukukhanya. Lokhu kukhanya has a nengcindezi enamandla, okuyinto luvela maphakathi inkanyezi, umphumela uba ukulingana phakathi kwengcindezi evela isikhungo kanye amandla elanga adonsela phansi.

Ngakho, ebiza izindikimba zasezulwini zikhanya ngokwabo, okungukuthi nezinkanyezi kukhanya ngokuhlinzekwa amandla eyingozi zenuzi. Lokhu amandla kuhloswe zokunqanda leli amandla adonsela phansi futhi ekushayweni ukukhanya. Luhlelo lolukhulu lwa okwengeziwe inkanyezi okuwukuthi, amandla ikhishwe, futhi licace ukukhanya izinkanyezi.

lezinkanyezi ezinomsila

Comet siqukethe ice ihlule, lapho amagesi, uthuli. Umnyombo awusebenzi ihlaba umkhosi ukukhanya, kodwa njalo lapho sishumayeza core kwelanga iqala igcwale amanzi nezinhlayiyana ngothuli, ukungcola, amagesi asakazeka emkhathini. Bakha uhlobo ifu hazy emhlabeni inkanyezi enomsila, okuthiwa - ikhoma.

Asinakusho ukuthi inkanyezi enomsila - nendikimba ethile esemkhathini okukhanya ngokwalo. Ukukhanya main ukuthi lukhipha, kubonakala ukukhanya kwelanga. Ukuba kude ilanga, inkanyezi enomsila akuyona ukukhanya ebonakalayo, futhi kuphela esondela nokwamukela imisebe yelanga, kuba sobala. Comet ngokwayo likhipha esincane ukukhanya ngenxa kuya kuma-atom ikhoma nezinhlayiyana ezincane ezishisa kakhulu zikhipha izinhlayiyana eziningi zokukhanya, ukukhanya kwelanga wathola. 'Umsila "we inkanyezi enomsila - a" uthuli ebhidlikayo ", okuyinto kuqokonyiswa ilanga.

emkhathini

Ngaphansi kwethonya gravity phezu iplanethi ungawela okuqinile emizimbeni cosmic, ababiziweyo emkhathini. Abanaso emsini emkhathini, futhi lapho sidlula it kushisa kakhulu futhi uqale ihlaba umkhosi ukukhanya okukhulu. Okunjalo meteorite elikhazimulayo ngokuthi i Meteor.

Ngaphansi yokucindezela moya Meteor niphihlizwe zibe yizicucu eziningi ezincane. Nakuba lishisa kakhulu, engxenyeni engaphakathi ngokuvamile uhlala abandayo, kusukela e ngakho iDemo isikhathi uwela, ayikwazanga ashisise ngokuphelele.

It lingahunyushwa baphetha ukuthi izindikimba zasezulwini zikhanya ngokwabo - izinkanyezi. Kuphela ziyakwazi ngenxa isimo sawo futhi izinqubo ezenzeka ngaphakathi ezishisa kakhulu zikhipha izinhlayiyana zokukhanya. Ngokwemibandela, singasho ukuthi meteorite - nendikimba ethile esemkhathini okukhanya ngokwalo, kodwa lokhu kungenzeka kuphela lapho singena emkhathini.
