Kukho enye inkcazo efunekayo ukwazi xa sibhekisela kwesi sihloko. Kumalunga nezo planethi zihlela ngolu hlobo, azizoplanethi ezincinci kodwa zinazo zonke iimpawu zesijikelezi-langa. Nangona kunjalo, azikho ngaphakathi kweSolar System. Ezi planethi zijikeleza enye inkwenkwezi kwaye zinamagama amabini: Iiplanethi ze-exoplanets okanye iiplanethi ze-extrasolar. Basenokuba kumnyele wethu: iMilky Way, okanye nakomnye.
imibala yeplanethi
Ukufunyanwa kwe ubukho beeplanethi, yabakho kumawaka eminyaka eyadlulayo. Nkqu nesithandi sobulumko esingumGrike uPlato nomfundi wakhe uAristotle babhala iindinyana zomfuziselo womhlaba owawusele ukho. Oku kwenzeka kwinkulungwane yesine BC Ngeli xesha, ubukho beePlanethi babusele busaziwa. Ngapha koko, imodeli ye-geocentric akhankanywa nguPlato nguAnaximander, isithandi sobulumko esingumGrike esasiphila phakathi ko-610 no-547 BC. c.
Unokuba nomdla kwinqaku lethu: Iinyanga zikaMars: Abantwana bePlanethi eBomvu
Kwanaxa okufunyenweyo kunye nemibuzo malunga nokuziphatha kweePlanethi, sele kumawaka eminyaka. Nangona kunjalo, Iiplanethi azikaziwa. Imibala yazo ayibonwanga ncam. Oko kukuthi, into ekucingelwa ukuba yeyona ilula, ineengxaki ezininzi emehlweni abantu, kunokuba kucingelwa. Uthini umbala wokwenyani weePlanethi?
Akukho mpendulo icacileyo kulo mbuzo, njengoko ingezizo zonke iiPlanethi ezinombala ofanayo. Abanye babonisa imibala kakhulu bukhali ngakumbi kunabanye, nangona kunjalo akunakutshiwo ukuba le yimibala yokwenyani. Ngokwenene ngamanye amaxesha, imalunga nemibala eboniswa kwiigrafu. Kwelinye icala, kukho iiplanethi ezigqunywe ngamatye kwaye zingwevu ngokwenyani, kodwa loo nto iguqulwe kwimifanekiso igcwele umbala.
Xa kukho uhlengahlengiso kuxa intandabuzo ifika. Into enokwenziwa kukuphanda, ngophando. Ukuba iplanethi ephandwayo ine- indawo enamatye kwaye umfanekiso owufumeneyo ugcwele umbala, unokuqiniseka ukuba lo mfanekiso awuyonyani kakhulu. Okwenzekayo kukuba ngokuqhelekileyo badla ngokuwubaxa iiyantlukwano ezichuliweyo ezazingenakubonwa liso lomntu, ngaphandle koncedo oluncinane.
ikhamera yefoto yendawo
Iikhamera zedijithali ezakhelwe kwii-smartphones zinezinto ezingaqhelekanga: izihluzi. Ezi zihluzo zibonisa iindlela ezininzi zokuzibaxa okanye ukuthoba i-hue yemibala. Unokuguqula ukukhanya kunye nokufudumala komfanekiso, kuxhomekeke kuhlobo lwezixhobo zombane onazo ezandleni zakho. Into efanayo yile isetyenziswayo xa kusetyenzwa imifanekiso efika ivela kwi iiteleskopu zasemajukujukwini.
Amaxesha amaninzi, ekuhambeni kwemifanekiso, imibala idla ngokugqithiswa. Kuyenzeka ukuba ikhamera ekwisiphekepheke ifane ibone imibala ngendlela efana nekhompyutha. iliso lomntu. Ngenxa yesi sizathu, iingcali kule ndawo kufuneka zisebenze ngendlela enokuthi zibonwe ngayo iliso lomntu. Umzekelo wale nto ibomvu, eluhlaza, kunye ne-blue components.
Ngokuqhelekileyo, zirekhodwa ngokwahlukeneyo njengemifanekiso emithathu eyahlukileyo emnyama nemhlophe. Idityaniswa ke ibe nemibala ngenjongo yokubonisa ifoto. Indlela exutywe ngayo imibala yenzelwe ukuba ibe ngendlela enokubonwa ngayo ngamehlo abantu. Nditsho imibala emfanekisweni azihambelani nezantlandlolo. Ukongeza kuloo nto, umfanekiso awunxulumananga nokuba akukho nzame yenziweyo ukuyibaxa.
Iikhamera ze iinqwelo banokubhala nayiphi na indawo ye-spectrum yokukhanya. Ukuba nawaphi na amajelo angaphaya koluhlu olubonakalayo, olufana ne-ultraviolet, kusafuneka usebenzise ebomvu, eluhlaza, okanye eluhlaza okwesibhakabhaka ukuze uyibonise. Oku kuthetha ukuba umfanekiso obangelwayo uno "mbala wobuxoki", onokuthi ugqithise ngakumbi.
Umbala wezigebenga zeSolar System
ISolar System yethu iseneemfihlakalo ezininzi ekufuneka iphononongwe. Enye yeeplanethi eziye zathimba ingqalelo yezazi ngeenkwenkwezi yi iplanethi iJupiter. Yenye yezigebenga zeSolar System kwaye ine "Great Red Spot", isaqhwithi esikhulu esimile okwe-oval. Yinyaniso ebangela umdla, kuba isijikelezi-langa sinemibala echubekileyo kwezinye iindawo zomhlaba. Amafu e-Granite angabonwa ukusuka kwi-space, ngokusebenzisa ubunzulu obuhlukeneyo bomoya.
Noko ke, amafu akwindawo kaJupiter adyojwe ebomvu sisingcoliso esingekaziwa nangoku. Omnye wemibuzo esinayo kukuba inokuba yi-phosphorus. Ukongeza koku, inokuba yinto ethile yesulfure okanye imolekyuli enzima yendalo. Esi sijikelezi-langa sithande ukuba nemibala eyomeleleyo kwaye kunjalo naso eyona nyanga ingaphakathi, onombala otyheli wendalo, ngelixa iYurophu idla ngokuphinda iphindwe.
Ngokutsho kwezifundo zenzululwazi ngeenkwenkwezi, kuye kwaphawulwa ukuba kwisathelayithi etyheli kukho ugqabhuko-dubulo lwentaba-mlilo rhoqo. Aba ngabo bahlamba umphezulu isulfure kunye nesulfure dioxide. Ezi zixhobo zikhankanywe ngasentla zezona zenza isathelayithi ibukeke njengepizza emthubi eneminquma emnyama. Enyanisweni, la machaphaza amnyama ngamabala e-lava amatsha kakhulu ukuba umthubi ukusuka kumacandelo abambelele kuwo.
Kwelinye icala Europe, inyanga elandelayo kaJupiter, inomphezulu wamanzi angumkhenkce. Yiloo nto ebangela ukuba isathelayithi ibonakalise ukuqaqamba okuqinileyo, ngaphandle kombala omninzi. Ngapha koko, uninzi lwemifanekiso efunyenweyo yaseYurophu ngombala idla ngokuphinda kuveliswe ngechromatic ebaxiweyo.
ISaturn kunye nemibala yayo
Imibala ukuba i IPlanethi yeSaturn, zizidenge kunezo zikaJupiter. Nangona kukho umoya ofanayo. Umbala wendalo weSaturn ngumbala ophuzi ophuzi. Oko kuthetha ukuba nayiphi na ifoto ebonwa ngeetoni ezibukhali kule planethi yinguqulelo kwinyani. Eli ayiloqhinga elisweni, kodwa kukutshintsha kwendlela elinokubonwa ngayo ngeliso lomntu.
Imibala yeUranus kunye neNeptune
Ezi zigebenga zimbini zeSolar System nazo zizimela phantsi kweatmosfera exinene ngokugqithisileyo. Amehlo ethu anokubona imibala yeUranus enemithunzi eluhlaza kakade INeptune yombala ozuba. Oku kungenxa yokuba amafu aphezulu anomthamo ophezulu wemethane ejiyileyo abonwa ngerhasi yemethane enzulu ehluza inxalenye ebomvu yokukhanya kwelanga.
Ngokwenyani, malunga neePlanethi ze Uranus kunye Neptune, akukho mahluko amaninzi ombala. Ekubeni amafu aphezulu akhangeleka amhlophe kodwa yonke enye into eluhlaza okwesibhakabhaka okanye eluhlaza. Kusekuninzi ekufuneka kuhlolisiswe e-Uranus, njengoko iyeyona planethi ingaqhelekanga nengazange iphononongwe kwiSolar System. Noko ke, ngokubhekisele kumphezulu, kuqikelelwa ukuza kuthi ga ngoku ukuba umbala wayo uluhlaza.
Iiplanethi ezinamatye
Enye yeeplanethi ezinamatye, nguMars. Le planethi idla ngokubizwa ngokuba yi "Iplanethi ebomvu«. Isizathu soku kukuba intsimbi esematyeni ayo nothuli ijika ibe yintsimbi oxide. Yiyo loo nto iplanethi ibonakala ibomvu kwiliso lenyama, xa siyibona esibhakabhakeni. Ngapha koko, ikwajongeka ibomvu ukusuka kwi-orbit, kwaye ibomvu kwi-probes ehlola umhlaba wayo. Kodwa eyona ngxoxo-mpikiswano yeyokuba ibonise imibala njengoko ibonwa na okanye ifanele iboniswe ngokungathi umgangatho wokukhanya kwesi sijikelezi-langa uyafana nowoMhlaba.
Kwelinye icala, enye iplanethi enamatye yekaVenus. Lo mmandla wasezulwini ugutyungelwe ngamafu amhlophe abengezelayo. I umphezulu wevenus iye yatyelelwa kuphela ligcuntswana le-Soviet probes. Amafu ayo ashinyeneyo avumela kuphela ukukhanya okubomvu okubuthuntu ukufikelela emhlabeni. Oku kubangela ukuba umbala o-orenji ubonakale kuyo yonke indawo. Noko ke, eneneni amatye eVenus luhlobo oluthile lodaka olungwevu olungacacanga.
Iplanethi yokuqala kwiindlela zeLanga, Mercury, lilizwe elingenamoya elenziwe ngelitye elingwevu nje elinentwana ebomvu. Le planethi ibonakalisa kuphela i-7% yokukhanya kwelanga okuwela kuyo, nangona isondele kakhulu. Kwaye oku kungaphezulu nje kancinane kunokuba ilahle elivuthayo lingabonisa, kodwa lisondele kathathu elangeni kunoMhlaba. Ngenxa yokusondela okufanayo kubonakala ukuba umntu ukhanya kakhulu.
Kodwa enyanisweni ukusondela kweMercury kuyimveliso yento eyenza i ukukhanya kwelanga yenza kuyo kwaye ke awudingi ukulungisa ukukhanya komfanekiso. Nangona kunjalo, ukuhlekisa ukuhluka kwemibala ehlala kwiimpawu zeMercury's landscape, kuye kwayimfuneko ukusebenzisa umbala ongeyonyani. Yile ndlela ekwenzeke ngayo ukunyusa umahluko ocacileyo kakhulu kumbala wendalo kwaye ubenze bavelele.
Ngaba kukho iplanethi efana nenye kwiSolar System?
Kwiintsuku ezimbalwa ezidlulileyo, ulwazi lwamva nje malunga neePlanethi lwavela. Oku kusixelela ukuba ngenene i-astronomy ayifuni kwaye akufuneki imise uphando kunye nemibuzo malunga nayo iziganeko zeenkwenkwezi. Into esandul' ukuboniswa liqela lezazi ngeenkwenkwezi kukuba kukho i-exoplanet eneempawu ezifana kakhulu nezo zeplanethi iJupiter. Iqela lezazi ngeenkwenkwezi lisebenze ngokubambisana neYunivesithi yaseMichigan.
Abaphandi banike ingxelo yokuba i iplanethi enkulu efana neJupiter. Nangona kunjalo, ayikho phakathi kwee-orbits zeSolar System, kodwa endaweni yoko ijikeleza inkwenkwezi ebekwe malunga ne-370 yeminyaka yokukhanya ukusuka eMhlabeni. Olu lwazi lwapapashwa kwiphephancwadi iAstronomy and Astrophysics.
Nangona ngokweempawu kuqikelelwa ukuba iyafana neJupiter, isijikelezi-langa esishushu nesinothuli esifunyenweyo, simalunga nesithandathu ukusa kwali-12 ubukhulu beJupiter. Ukongeza koku, yenye yeeplanethi ezilishumi elinambini ezinobunzima obufanayo kunye ne-orbit. Umjikelo wesijikelezi-langa esandula ukufunyanwa mkhulu kakhulu: Umjikelo weJupiter umalunga neeyunithi ezintlanu zeenkwenkwezi ukusuka eLangeni.Kwelinye icala, le yesi sijikelezi-langa sisandul’ ukufunyanwa malunga neeyunithi ezingama-90 zeenkwenkwezi yinkwenkwezi yakhe.
Ukuchonga ukuba yintoni na umlinganiselo weyunithi yeenkwenkwezi, kuyimfuneko ukucacisa ukuba ngumgama ophakathi koMhlaba kunye neLanga.Ngale ndlela, ii-orbits zezinye iiPlanethi zilinganiswa, zithatha zethu njengesiseko sokuba yiplanethi esiphila kuyo.
ukusekwa kweeplanethi ezinkulu
Ukufunyanwa okutsha kweplanethi efana neJupiter kukhokelele izazi ngeenkwenkwezi ukuba ziphande ukuqonda okunokwenzeka Zenziwa njani ezi planethi zinkulu?. Nangona izazinzulu zikwabonisa ukuba akukabikho isampulu enkulu ngokwaneleyo yokuqonda idemographics yezi planethi. Nangona kunjalo, kukho izinto ezimbalwa ezinokubonakaliswa ukuvavanya iimpawu zabo zomntu ngamnye.
Ekubeni izazi ngeenkwenkwezi ziye zakwazi ukujonga izijikelezi-langa ezikude neenkwenkwezi, sekudlule iminyaka embalwa. Le yokugqibela yabanjwa eChile. Ngenxa yoko, a ITelescope enkulu kakhulu (VLT). Le sathelayithi yasemajukujukwini inomlinganiselo weemitha ezisi-8,2. Ukongezelela, isetyenziswa yi-European Southern Observatory kwaye inxalenye yenkqubo enkulu ebizwa ngokuba yi-SHINE.
Inkqubo ye-SHINE, inenjongo ephambili yokukhangela iiPlanethi. Kule nto, isebenzisa isixhobo se-VLT esibizwa ngokuba yi-SPHERE (Khangela ii-Exoplanets ezine-High-Contrast Spectro-Polarimetry). Ukuqala kwayo kuqale malunga neminyaka emithathu edlulileyo. Into yokuqala eyenziwa zizazi ngeenkwenkwezi kukukhangela idatha yeVLT. Ukwenza oku, kwakuyimfuneko ukukhangela iiplanethi ezinokwenzeka, ukuhlawula ingqalelo ekhethekileyo kwiindawo ezingabonakaliyo kufuphi neenkwenkwezi ezikhanyayo.
Kubaphandi, lo msebenzi ufana nokuzama ukubona i-firefly kufuphi ne-lighthouse. Ayinakwenziwa okwangoku, enyanisweni ayinakwenzeka. Kodwa ukuba kusetyenziswa imifanekiso yedijithali, isixhobo sokuthintela ukukhanya sibizwa i-coronagraph ukunceda ukuthintela ukukhanya kwenkwenkwezi, kunye ne-algorithms ephucukileyo yenza kube lula ukufumana ukhanyikhanyi. Kwaye eso sisixhobo kanye esisetyenziselwa ukubona ii-exoplanets.
Uphendlo lwePlanethi
Ukongeza koku, iSPHERE ikwabuyekeza isiphumo somfiliba kwiatmosfera yoMhlaba. Oku kufezwa ngokusebenzisa ubuchule obubizwa ngokuba ngokukhanya okuguqukayo. Ngokwahlukileyo, abaphandi basebenzise idatha evela kwiteleskopu ukuchonga amakhulu eeplanethi ezinokubakho. Ezi ziinkwenkwezi ekunokwenzeka ukuba ziinkwenkwezi kungekhona iinkwenkwezi ezijikelezayo.
Emva koku, kwathelekiswa ezinye izinto ekuthethwa ngazo. Kwaneentshukumo ezilindelekileyo zesijikelezi-langa ezihambelana neenkwenkwezi zaso zathelekiswa. Ngesi sihlandlo, izazi ngeenkwenkwezi ziye zakwazi ukuchonga ukuba loo nto yiplanethi okanye a inkwenkwezi ekude. Kodwa ukufumanisa le planethi ifana neJupiter, inkqubo ithathe malunga nonyaka ukusuka kuqwalaselo lokuqala.
Abaphandi kwafuneka bajonge kwikhulu lokuqala labaviwa ababenabo. Bandula ke benza uludwe lwamashumi amaninzi ekufuneka bewalandele ngokuphambili. Zalahlwa nganye nganye, uninzi lwazo zaliwe njengoko kunokwenzeka iiplanethi. Nangona kunjalo, le, efana neplanethi iJupiter, yasinda kuzo zonke iimvavanyo. Ukukhululeka okukhulu kwiqela lophando, njengoko le nto yayiyeyona nto isixhobo sakhulelwa ngaphezu kweminyaka elishumi edlulileyo.
Isijikelezi-langa esafunyanwa sijikeleza a inkwenkwezi encinci. Inkwenkwezi yathiywa zizazi ngeenkwenkwezi njenge-HIP65426. Kuqikelelwa ukuba le nkwenkwezi ineminyaka ephakathi kwe-10 ukuya kwi-20 yezigidi zeminyaka. Iselula, xa ithelekiswa neLanga, elineminyaka emalunga ne-4.500 yeebhiliyoni ubudala. Ukongeza koku, iplanethi entsha nayo incinci kakhulu kuneJupiter. Ngenxa yoku, kushushu kakhulu, malunga ne-2.150 degrees xa kuthelekiswa ne-234 degrees Fahrenheit.
Iimpawu zesijikelezi-langa esitsha
Ukongeza kwinto yokuba isijikelezi-langa esifunyenweyo sineempawu zokuba kushushu ngakumbi kuneJupiter, izazi ngeenkwenkwezi zibonisa ubukho bamanzi. Ngokutsho kohlolisiso, kukho amanzi kwesi sijikelezi-langa nobungqina bamafu. Ezi ziimpawu ezifanayo nezimbalwa Iiplanethi ezifanayo abanemifanekiso yabo ithinjiweyo.
Iiplanethi ezinomdla kakhulu kwi-space
Olo kufunyanisiweyo lolona lwamva nje ngokubhekisele kwiiPlanethi. Inzululwazi isaqwalasela njengoko sifunda eli nqaku. Izazi ngeenkwenkwezi ziyaqhubeka zihlola isibhakabhaka. Kwaye ngelixa ukukhangela iiplanethi ngaphandle kwethu ISistema Solar, ngoku kukho amazwe amaninzi aziwayo aneempawu ezigqithisileyo kwaye afanele ukukhankanywa.
Eyona planethi ibanda kakhulu emajukujukwini
Ngaphandle kweSolar System, kunye nobushushu obumalunga nama-50 degrees ngaphezu kwe-zero (-223 ° C), iplanethi ye-extrasolar OGLE-2005-BLG-390Lb iyaqhayisa, kude kube ngoku, isihloko eyona planethi ibandayo. Eli hlabathi limi kumgama weminyaka engama-20.000 yokukhanya ukusuka eMhlabeni, kwiqela leenkwenkwezi zeSagittarius. Ummelwane womnyele wethu, ekubeni ukufutshane kakhulu kumbindi weMilky Way.
Inkwenkwezi ejikeleza esi sijikelezi-langa inobunzima obuphantsi. Yinkwenkwezi epholileyo eyaziwa ngokuba yi-red dwarf. Eyona nto imangalisayo kukuba iplanethi ijikeleza i-80 yezigidi zeekhilomitha ukusuka kwenkwenkwezi yayo, ngaphantsi komgama ophakathi kweJupiter kunye neLanga. engakwaziyo ukuxhasa ubomi kwaye uninzi lweegesi ezikwiatmosfera ziya kuba ngumkhenkce phezu komhlaba. Yafunyanwa ngo-2006 kwindawo Iindawo zokujonga i-ESO eChile.
Eyona planethi ishushu esithubeni
Ukufumana ubushushu obukhoyo kwisijikelezi-langa, kuxhomekeke ikakhulu kumgama osuka kwinkwenkwezi yayo. Ngokucacileyo kukwabalulekile ukwazi iimpawu zenkwenkwezi ngokwayo eyijikelezayo. Kweyethu iSolar System, iMercury, umzekelo, yi iplanethi ekufutshane elangeni ngomgama ophakathi kweekhilomitha ezingama-57.910.000. Nto leyo eyenza ibe yiplanethi eshushu ngakumbi kuneyethu.
Ubushushu beMercury, kwicala layo le-diurnal, bunokufikelela kuma-430 ºC. Kwelinye icala, iLanga linayo a ubushushu bomphezulu be-5.500 °C. Nangona kunjalo, oku kushushu njengoko sisazi? Kwinqanaba lendalo iphela, kukho iinkwenkwezi ezinkulu kakhulu kuneLanga kwaye kushushu kakhulu.
