Ukuba ucinga wethu iplanethi kwakungalunganga kufuneka uzame ukuhambela kwiplanethi engu-K2-141b.
Izazinzulu ziye zakhomba into abathi zezinye zeeplanethi ezigqithileyo ezakha zafunyanwa kwimiphetho yethu inkqubo yesola . Ugqithise kangakanani, ubuza? Ewe, iilwandlekazi zenziwe ngodaka olunyibilikisiweyo ukuqala. Owu, kwaye ikwanetha namatye kwaye inomoya ongaphaya kwamandla.
Uphononongo lolokuqala ukwenza uqikelelo malunga nemozulu kwi-K2-141b enokufunyanwa kumakhulu-khulu eminyaka ekukhanyeni kude kunye neeteleskopu zesizukulwana esilandelayo ezifana neJames Webb Space Telescope, uGiang Nguyen, umfundi wePhD kwiYunivesithi yaseYork, kunye Umbhali ophambili wesifundo, utshilo .
Ababhali babelana, njengomjikelo wamanzi woMhlaba ubangela ukuba amanzi anyuke abe ngumoya aze awe kwakhona njengemvula, kukwanjalo nakwisodium, i-silicon monoxide, kunye ne-silicon dioxide kwi-K2-141b. Oko kuthetha ukuba umphunga wamaminerali uyaphuma kwaye uphinde uwe kwakhona njengemvula yelitye.

Ngelixa oku kunokubonakala ngathi kuyindalo ngokupheleleyo, yinkqubo yomhlaba ekusenokwenzeka ukuba ihambile, nayo.
Zonke iiplanethi ezinamatye, kubandakanya noMhlaba, zaqala njengehlabathi elinyibilikisiweyo kodwa zaphola ngokukhawuleza kwaye zaqina. Iiplanethi zeLava zisinika umbono onqabileyo ngeli nqanaba lendalo, utshilo uNjingalwazi Nicolas Cowan, owayongamele olu phononongo.
Ngaphandle kolwandle olutyhidiweyo kunye nemvula enamatye, ababhali bafumanisa ukuba malunga nesibini kwisithathu seplanethi sihleli emini engapheliyo. Oku, ababhali bachaza, kungenxa yokusondela kweplanethi kwinkwenkwezi yayo, eyigcina itshixiwe endaweni. Kwaye ngelixa elinye icala lihleli elangeni elinaphakade, elinye lihleli ebumnyameni obupheleleyo, elibangela ukuba icala libe namaqondo obushushu angaphantsi kwe - 200 degrees celcius.
Ukufumanisa kwethu kuthetha ukuba iatmosferi iyolulela ngaphaya kolwandle lwamagma, isenza ukuba kube lula ukuyibona ngesibonakude sasemajukujukwini, utshilo uCowan.
Emva koko, izazinzulu ziya kuvavanya iingqikelelo zazo kwimozulu yasendle esemhlabeni zisebenzisa idatha ethe kratya kwiSpitzer Space Telescope, ekufuneka ibanike imbonakalo echanekileyo nangakumbi kumaqondo obushushu ayo. Okwangoku, unokusebenzisa olu lwazi njengombono wokuba iplanethi yethu ayinabungozi kakhulu. Kwaye mhlawumbi uyisebenzise njengokhuthazo yenza into entle kuMama Wendalo namhlanje.
