Kukho ngaphezulu kwezigidi ezingama-300 zeeplanethi ezinokuhlalwa kumnyele wethu, ngokutsho kwesifundo esitsha esivela kwi-NASA, kunye neeplanethi ezininzi ngakumbi kuneenkwenkwezi.
Inkqubo ye- ukufunda , ngokusekwe kuphando olusuka kumhlala-phantsi wase Kepler osethathe umhlala-phantsi osetelwe ukupapashwa kwi-Astronomical Journal. ikwanayo neplanethi enamatye ekwaziyo ukuxhasa amanzi angamanzi kumphezulu wawo. Ubuncinci ezine kwezi zijikelezi-langa ekunokuhlalwa kuzo zingaphakathi kwe-30yeyeye kwaye ezona zisondeleyo zikwi-lightyears ezingama-20, ngokweNASA.
'Nangona esi siphumo sikude nexabiso lokugqibela, kwaye amanzi kwiplanethi kunye nomphezulu womhlaba yenye yezinto ezininzi zokuxhasa ubomi, inomdla kakhulu ukuba sibala ukuba le mihlaba iyafana nokuzithemba okuphezulu nokuchaneka,' USteve Bryson, umbhali ophambili wesifundo kunye nomphandi kwiZiko loPhando lwe-Ames eCarlifonia, yatsho kwingxelo . Kum, esi siphumo singumzekelo wokuba singakanani thina & apos sikwazile ukufumanisa nje ngokujonga kancinci kwenkqubo yethu yelanga. Into esiyibonayo kukuba umnyele wethu unomdla, unamazwe anomtsalane, kwaye eminye isenokungafani kakhulu neyethu. '
UKepler-186f Lo mzekeliso ubonakalisa iKepler-186f, iplanethi yokuqala eqinisekisiweyo yobungakanani bomhlaba ukujikeleza inkwenkwezi ekude kwindawo ekuhlalwa kuyo. | Ityala: I-NASA Ames / JPL-Caltech / T. Pyle
I-teleskopu yendawo yaseKepler ichithe iminyaka esithoba esithubeni yada yathatha umhlala-phantsi ngo-2018 emva kokuphela kwepetroli.
Olu phando lutsha lubalule ngokukodwa ubudlelwane phakathi kobushushu benkwenkwezi kunye nohlobo lokukhanya elikunikileyo elifunxwe yiplanethi, ivumela izazinzulu ukuba ziphendule kuluhlu olubanzi lweenkwenkwezi ngaphandle.
`` Ayizizo zonke iinkwenkwezi ezifanayo, '' utshilo uRavi Kopparapu, umbhali kwiphepha kunye nesayensi ye-NASA kwingxelo. Kwaye ayisiyiyo yonke iplanethi. '
Iziphumo zifike nje kwiveki emva kokuba i-NASA iqinisekisile ubukho bamanzi enyangeni nanjengoko ilungiselela Qalisa umsebenzi we-NASA kunye ne-SpaceX kwiSitishi saMazwe ngaMazwe sasemaJukujukwini.
I-NASA ikwaceba ukuthumela i umfazi wokuqala kunye nendoda elandelayo ebusweni benyanga ngo-2024 ngaphambi kokuba iarhente isete izinto zayo eMars.
