Ilanga linhloboni yenkanyezi?

Isidingo esikhulayo samandla emhlabeni wethu sidinga ukwakhiwa kwemithombo emisha. Kunemibono emisha ngeLanga edinga ukulihlola ngamehlo amasha, njengokuthi umthombo wamandla ongenamkhawulo.

ILanga manje linikeza isintu umthombo wamandla ongahlangabezana nazo zonke izidingo zaso. Ukusetshenziswa kwalokhu kuba yimpumelelo kakhulu futhi sibonga ngempumelelo Ilanga. Kodwa, ngempela ILanga liluhlobo luni lwenkanyezi? Lapha sikutshela lokhu nokunye.

ilanga nokuphila

ILanga liwumthombo oyinhloko wawo wonke amandla kithi, ngokomzimba noma ngokungaqondile. Izitshalo nezilwane zidinga ukukhanya kwelanga ukuze ziphile. Izitshalo ziguqula ukukhanya kwelanga kube ukudla ngokusebenzisa i-photosynthesis. Le nqubo efanayo futhi indlela umhlaba wethu wadalwa ngayo.
izidalwa eziningi zithembele ezitshalweni ukuze zidle.

Ezigidini zeminyaka edlule, izitshalo nezilwane zaqhekeka zaba izinto zokubasa ezimbiwa phansi njengamalahle, uwoyela negesi yemvelo. Lokhu kuhlanganisa izitshalo nezilwane ezifile. Amandla enuzi akhiqizwa emhlabeni wethu avela emandleni eLanga futhi abangela imimoya yasemkhathini nemisinga yasolwandle. Futhi izinsimbi ezisindayo zakha cishe phakathi nendawo yeLanga.
Eqinisweni, isimiso sonozungezilanga singokwesibili emvelweni ngoba siwumkhiqizo, owakhiwa lapho iLanga lidalwa.

Kodwa iLanga liluhlobo luni lwenkanyezi?

Emthaleni ongenakuzidla, iLanga libonakala liyinkanyezi ejwayelekile. ILanga liyinkanyezi yohlobo lwe-spectral G2 kanye nesigaba sokukhanya V ku-astronomical terminology.. Lokhu kusho ukuthi iyinkanyezi encane ephuzi enezinga lokushisa 5778 ama-grados Fahrenheit. Ingaphezulu K1 ine Amamitha ayi-5780 ububanzi.

I-Hydrogen yenza u-74% , yakhiwe cishe ngokuphelele yileso sici. Ukukunikeza umbono, inesisindo esingu-92% wevolumu yayo futhi iqukethe isisindo esilingana nethangi elivamile le-helium. Okuqukethwe kwayo kwe-helium kungu-24,5% ngobuningi kanye no-7% ngevolumu.. Ngaphezu kwalokho kunezinsimbi ezincane ezisindayo, njengensimbi, i-nickel nomthofu, ezihlala kuyizinhlayiya ze-subatomic.
Ezinye izakhi ezifana ne-silicon, isulfure, i-magnesium, i-carbon, umoya-mpilo, ne-calcium zibalwe njengezakhi ezengeziwe kulolu hlu.

I-Curiosities of the Sun

Lezi ezinye zezinto ezithakazelisa kakhulu zeLanga:

• ILanga libukeka lingenasidingo njengoba lisendaweni engenancazelo ethile.
• Isikhungo se-Galaxy cishe Iminyaka engu-26.000 yokukhanya ukusuka eMhlabeni. Ukuze ufike lapho, umdlali kufanele ahambe cishe iminyaka engama-900 yokukhanya. I-nebula iqhele cishe nge-light-year engu-60.000, emaphethelweni angaphakathi kakhulu engalo ezungezayo ye-Orion.
• ILanga lihamba ngesivinini esingamakhilomitha angu-214 ngomzuzwana..
• Ukuze sibone yonke le ndawo ngamehlo ethu amancane, kwakuzodingeka sihambe unyaka owodwa wokukhanya njalo ngemva kweminyaka engu-1 1.400. Lokhu bekungathatha abahambi amakhilomitha angu-200.000 120 noma ibanga eliphindwe izikhathi ezingu-XNUMX ukusuka eMhlabeni ukuya eLangeni. IMilky Way, inezinkanyezi eziyisigidi.
• ILanga lethu liwela ohlotsheni lwe-G2 lwezinkanyezi eziyizigidi eziyi-100, u-85% wazo okuyizinto ezincane ezibomvu ezilufifi kunenkanyezi yethu.
• Emini, iLanga lethu liphuphuthekisa ezinye izindikimba zasezulwini neyakhe
• ukukhanya okukodwa. Kunzima ukuyibona ngqo ngenxa yokukhanya kwayo. ILanga likhuthaze ukuhlola kanye nelukuluku kuwo wonke amasiko.
• Abantu basendulo babembheka njengonkulunkulu futhi bakha nezithombe ukuze bamhloniphe.
• Amanyuvesi amakhulu kanye nezindawo zokubuka izinto zikhona emhlabeni wonke. EGibhithe, eGrisi naseMelika, kanye nase-Asia naseMpumalanga, kunenqwaba yezindawo zokubuka izinto.
• Ukuba khona kwezibonelo ezingenakubalwa ezithakazelisayo nezingavamile emhlabeni wonke ibonisa ukuqonda nokuqaphela ukukhanya nokushisa KweLanga njengemithombo yamandla esekela ukuphila.

Ingabe zikhona ezinye izinkanyezi ezifana neLanga?

Izazi zezinkanyezi zikuthola kunzima ukuthola izinkanyezi ezibonisa ukubonakala kweLanga njengenkanyezi evamile. Lokhu kungenxa yokuthi iLanga liwumthombo wokukhanya oyingqayizivele wezazi zezinkanyezi. Izinhlelo zokusebenza zezinkanyezi kwesinye isikhathi zisebenzisa amawele ukulinganisa.

Ukuba seduze kweLanga kumathuluzi ethu kwenza kube nzima ukuwasebenzisa njengezinga elijwayelekile. Futhi, ukukhanya kwayo kwenza kube nzima ukuyisebenzisa njengezinga lokulinganisa.

Ukusesha izinkanyezi ezifana neLanga kuveze imiphumela engaphelele. Azikho kulezi zinkanyezi ezisamukelwe njengabalingani neLanga.

Izinkanyezi I-18 Scorpion (HD142633) y I-HIP56984 zingaseLangeni lokho iso lakho eliyikho kuwo wonke umzimba walo. Kukhona ososayensi abathi i-18 Scopii ifana neLanga ngezindlela eziningi, kodwa kuhlukile kwezinye izici. Isibonelo, ihluke ngokuthi inesisindo esiningi. Futhi ine-lithium ephindwe kathathu inezikhathi ezi-3 ngaphezu kweLanga.

Ngokombono wesayensi, iLanga libonakala lingenakuhlukaniswa nekhaya lethu. Kodwa kunendikimba yasezulwini ekude, cishe iminyaka engama-200 yokukhanya ukusuka eLangeni, efana kakhulu neLanga lethu ngeminyaka, okwenza umuntu ofanelekayo ukucinga amaplanethi afana noMhlaba. Uma kutholakala ubufakazi, imisebenzi yesikhathi esizayo ihlelelwa ukuthola la maplanethi. Lokhu kuholela emcabangweni wokukwazi ukucinga impilo yangaphandle.

ubudala belanga

Ilanga lineminyaka eyizigidi eziyizinkulungwane ezingu-4.500. kodwa ingqikithi yayo isebenzise ingxenye ye-hydrogen yayo kuphela. Ukuhlaziywa kwamakristalu e-hibonite amancane kunemilimitha kwembula iminyaka yenkanyezi enkulu kunazo zonke kusistimu sonozungezilanga.

Kuthatha cishe iminyaka eyizigidi eziyizinkulungwane eziyi-10, izinkanyezi ezinjengeLanga zikhanya ngokukhazimulayo ngaphambi kokufiphala. Lokhu kusiza ukuchaza ukuthi kungani iLanga liphakathi nendawo yalo yokuphila.

ILanga liwakhiqiza kanjani amandla alo?

ILanga kuthiwa liyibhola legesi elishisayo elishintsha kakhulu indawo yalo engaphakathi impela. Ngokucacile, lokhu kubhekisela engxenyeni emaphakathi yeLanga. Irediyasi yalo esuka eLangeni icishe 0,2 imisebe yelanga, okwenza kushise ngokwedlulele ngokwezindinganiso zezinkanyezi. Eqinisweni, iyi-reactor enkulu ye-athomu efinyelela kuma-degree ayizigidi eziyi-15.

Izingxenye ezintathu kwezine zobunzima beLanga zakhiwe ama-athomu e-hydrogen.. Futhi umnyombo wenuzi ubamba i-hydrogen eningi kunanoma iyiphi enye indawo. Ama-athomu e-helium alula akhiwa ngokuhlanganisa ama-athomu amabili e-hydrogen.

Ngaphambi kokuba i-Helium itholwe emhlabeni, yayitholakala eLangeni, igama lale nto livela kunkulunkulu wamaGreki Helios, umsebenzi wawo kwakuwukukhulekela ilanga.

Ekupheleni kokuguqulwa kusuka ku-hydrogen kuya ku-helium, ingxenye encane ye-compound isala. Izixuku ezingu-0,7% ziguqulwa zibe amandla ngokuvumelana nefomula ye-Einstein yento.

ILanga liguqula izikhathi ezingu-3.400 XNUMX inani lama-proton aqukethwe ngomzuzwana ngamunye libe yi-helium nuclei. Le nqubo yakha mayelana 3.860 billion watts. Njalo ngomzuzwana kukhiqizwa amathani ayizigidi ezingu-582 egesi ye-hydrogen.

Ukuguqulwa kwe-helium kusuka ezintweni zangempela kudinga amathani ayizigidi ezingu-5 zezinto. Ibhomu lenuzi linesilinganiso esingamamegathoni angu-90 wamandla. Ngakho-ke, ingakhiqiza isilinganiso esingaba ama-megatons angu-9 quadrillion wamandla.

Izikhala zelanga

Amandla kazibuthe adalwe nxazonke zelanga ngamaza kagesi ukuzungeza into ene-ionized ezungeze indilinga. Njengoba ilanga lizungeza futhi lidala i-convection, imigqa kazibuthe iwela ngokwemvelo ebusweni bomzimba wakho. Uma imigqa kazibuthe icindezelwa bese inwetshwa, lokhu kubangela umfutho uyashintsha ezindaweni ezithile elangeni. Ngale migqa yelanga yamandla ejika ibe yizicucu ezinesono, futhi zombili izindawo zihlukaniswa indawo yesithathu engathathi hlangothi. Izici ezimbi ze-magnetism zikhona ngaphakathi kwezifunda ezichazwe kulo mbhalo.

Indawo engakhanyi kakhulu futhi emnyama kune-epiphase eyakhiwe, i i-photosphere. Izifunda ezimnyama kakhulu ze-photosphere zivame ukubizwa Izikhala zelanga. Ukukhanya okulinganiselwe okukalwa ngakho ngu I-4200 K. Lokhu kunqunywe ngokungafani nokukhanya kwe-5800 K. Lawa maphuzu Ngokuvamile zivela ngababili noma ngamaqembu amalungu amaningana. Ngaphezu kwalokho, ngokuvamile zivela kanye nesithombe esibi. Futhi amasonto ambalwa, lesi simo siyaqhubeka.

Ngithemba ukuthi lesi sihloko mayelana nokuthi hlobo luni lwenkanyezi iLanga lube wusizo kuwe.
