U-Nasa, Esa kanye no-Csa bakhiphe izithombe zakamuva ze-Saturno ezithathwe izibonakude ze-James Webb kanye ne-Hubble. Izithombe zethula iplanethi ngezindlela ezihlukene, i-Webb isebenzisa ukukhanya kwe-infrared kanye ne-Hubble ithwebula ukukhanya okubonakalayo. Lokhu okuqashelwe kwenzeka cishe amasonto ayi-14 ngokuhlukana ngo-2024 futhi kuveza imininingwane yomoya onyakazayo wale nkunzi yegesi.
Lokhu kuthwebula kwenza kube nokwenzeka ukuhlaziya amafu namakhemikhali ekujuleni okuhlukahlukene. Enquanto isithombe esisodwa sigqamisa ukuhluka kwemibala ecashile kumabhande wamafu nenkungu, esinye singena ezingqimbeni ezijulile, ezingaphezulu zomkhathi. Saturno Izindandatho zibonakala zikhanya ngenxa yeqhwa elicwebezelayo.
Ukubuka okuhambisanayo kweplanethi
Izithombe zibonisa i-Saturno enezimpawu zayo zamasongo nezici ezihlukile zomkhathi. Isibonakude se-James Webb sirekhoda amafu ezindaweni eziphakeme ezihlukene futhi sithola izinhlanganisela zamakhemikhali ezikhona ezindlaleni ezihlukahlukene. Umthamo we-Essa uvumela ukuthi ufunde izinqubo eziguquguqukayo ezenzeka emkhathini.
I-Hubble, nayo, iveza umehluko ocashile ngombala obangelwa amabhande wamafu nenkungu. Le mibono emibili ihlangene inikeza ukuqonda okuphelele okwengeziwe kwesakhiwo seplanethi. Idatha ibonisa ukuthi i-Saturno isenguqukweni yesizini enyakatho nenkabazwe.
- Ukubuka okwenziwa ngo-Agasti 2024 ngu-Hubble kuyingxenye yohlelo lwe-Outer Planet Atmosphere Legacy.
- Isithombe se-Webb esithwetshulwe ngoNovemba 2024 sihambisana namarekhodi adlule.
- Isikhawu samaviki angu-14 phakathi kwezithombe sisivumela ukuthi siqhathanise izinguquko zomkhathi.
- Womabili amathuluzi athola ukukhanya kwelanga, kodwa ngamaza ahlukene.
Imininingwane ye-atmospheric evezwe yizithombe
Amathoni ampunga naluhlaza aseduze nezigxobo abonakala ngokucacile kwesinye sezithombe. Amaphethini angu-Esses angase ahlobane nemisebenzi ye-auroral esifundeni se-polar. I-infrared ye-Webb isiza ukukhomba izakhiwo ezifana neziphepho namagagasi akha emkhathini.
Amabhendi amafu abonisa ukuhluka okubonisa ukunyakaza okuguquguqukayo emhlabeni. Ukujula kokubukwa kusivumela ukuthi sikwazi ukuhlukanisa phakathi kwezingqimba zamafu ezijulile nezifunda ezincane emkhathini ongaphezulu. Essa inhlanganisela yedatha inothisa ulwazi mayelana nokuziphatha kwe-gas giant.
Amasongo akhanya ngokugqamile embonweni we-infrared ngenxa yobukhona beqhwa elimsulwa. Isici se-Essa sigqamisa ukwakheka kwamasongo kanye nokusebenzisana kwawo nokukhanya kwelanga. Amarekhodi afaka nokubukwa kwezinye zezinyanga ezinkulu ze-Saturno.
Ukuhlaziywa kokubhekwa okuhlanganisiwe
Ubambiswano phakathi kwalezi zibonakude ezimbili kunikeza imibono egqamisa izici ezihambisanayo zeplanethi. I-Hubble inikeza ulwazi mayelana nokwehluka okubonakalayo endaweni ebonakalayo, kuyilapho i-Webb iphenya ingaphakathi lezendlalelo zomkhathi. Indlela ye-Essa iveza imininingwane ebingeke ifinyeleleke ngesisetshenziswa esisodwa kuphela.
Izithombe zithathwe ngesikhathi esiseduze, okwenza kube lula ukuqhathanisa imiphumela ngqo. I-Cientistas isebenzisa le datha ukutadisha ukuvela kwesizini kwe
Izithombe zigqamisa uguquko lwesizini
ISaturn inezinguquko ezihamba kancane ezinkathini zayo zonyaka ngenxa yokutsheka kwayo kwe-axial kanye nesikhathi eside sokuzungeza. Izithombe zakamuva zithwebula iplanethi isesenhla nenkabazwe ehlobo, ngaphambi kokushintshela ekwindla. Isigaba se-Essa sikuvumela ukuthi urekhode amaphethini omkhathi athile nesikhathi.
Amarekhodi aneqhaza ekuqashweni okuqhubekayo kwezimo emhlabeni. Amaza amaza angu-Diferentes aveza ukuthi ukukhanya kusebenzisana kanjani nezinhlayiya ezimisiwe emkhathini. Inhlanganisela yamathuluzi ikhulisa ukuqonda kokuguquguquka komhlaba wonke kwe-Saturno.
Isakhiwo sendandatho nezifunda ezipholile
Amaringi abonakala ekhanya kakhulu ekuthwebuleni kwe-infrared ngenxa yokubonakala kweqhwa. Isici se-Essa sikuvumela ukuthi wenze imephu yokusatshalaliswa kwempahla emasongweni ngokunemba okukhulu. Ososayensi bahlaziya ukuthi lezi zakhi zihlangana kanjani nezizibuthe zeplanethi nezinhlayiya ezishajiwe.
Ezifundeni ze-polar, amathoni abhekiwe aphakamisa izinqubo eziqhubekayo zamandla. Ukutholwa kwezakhiwo ezinama-hexagonal noma imifudlana yejethi emkhathini kwengeza ulwazi mayelana namaphethini omjikelezo. Essas izici zihlala zizinzile isikhathi eside futhi zisebenza njengesithenjwa sezifundo zesikhathi eside.
Igalelo ekutadisheni amaplanethi amakhulukazi
Izithombe ezintsha ziqinisa ukubaluleka kokubuka okuhlangene okuvela kumabonakude asemkhathini. I-James Webb kanye ne-Hubble zisebenza nge-spectra ehlukene, ekhiqiza idatha ehambisanayo ekubunjweni komkhathi nokunyakaza. Essa isu lisetshenziswe ngempumelelo kwezinye izindikimba kusistimu sonozungezilanga.
Amarekhodi akamuva we-Saturno engeza kungobo yomlando yeplanethi yokubonwayo. Eles vumela ukuqinisekiswa kwamamodeli wetiyetha ekwakhekeni nasekuguqukeni komkhathi kuma-gas giants. Ukufinyelela ekujuleni komkhathi okuningi kumelela intuthuko emandleni okuhlaziya okude.
Izinyanga ezinkulu ze-Saturno nazo zivela kokunye ukubuka okubanzi. Ukuba khona kwe-Titan okugqanyisiwe kwesinye sezithombe kukhulisa umongo wesistimu ye-Saturn. Imininingwane ye-Esses isiza ukuhlanganisa imvelo ezungeze iplanethi eyinhloko.
Intuthuko ngokuningiliziwe ithwebula
Ubuchwepheshe be-telescope benza kube nokwenzeka ukunqoba ukulinganiselwa kokubhekwa komhlaba. I-infrared ingena ezindaweni ukukhanya okubonakalayo okungafinyeleli kuzo ngokucaca okufanayo. Essa amandla embula izakhiwo ezinhle nokuhluka okuhlala kufihliwe ekurekhodweni okuvamile.
Ososayensi bayaqhubeka nokucubungula idatha ukuze bakhiphe ulwazi olwengeziwe mayelana namakhemikhali asemoyeni. Ukuqhathanisa amadethi okuthwebula kusiza ekuboneni ukuhlukahluka kwesikhashana okucashile. Esse uhlobo lokuhlaziya lunikela ekuhlelweni kwemishini yesikhathi esizayo ohlelweni lweSaturn.
Izithombe ziyatholakala ukuze kuboniswane nomphakathi futhi zisebenza njengereferensi yabacwaningi nabathandi besayensi yezinkanyezi. I-Elas ibonisa amandla aqhubekayo wezimboni zasemkhathini ukuze zinikeze ukubuka kwakamuva kwamaplanethi akude.
