Ukusukela ekuqaleni kuka-2017 ubukho be UMNTU-1 Zininzi iindaba eziye zafikelela kuthi malunga nokuba kungenzeka ukuba kubekho uhlobo oluthile lobomi kulo, ngenxa ye-morphology, nangona, kungekudala, zonke ezi ziboniso, ukubabiza ngandlela thile, ziye zaboniswa kancinci kancinci, nokuba Abaqinisekanga ngokwaneleyo okanye, emva kophando olwahlukileyo, babonakalisiwe ukuba akunakwenzeka.
Nangona kunjalo, namhlanje ndifuna ukukuxelela malunga nokufumanisa okutsha okunokuba ziindaba ezimnandi. Ngokwabaphengululi abahlukeneyo kunye nabaphandi abaziingcali, kuyacaca ukuba le nkqubo yelanga ibekwe kungekho ngaphantsi kweminyaka engama-39 yokukhanya ukusuka eMhlabeni, iqulethe kungekuphela iiplanethi ezikuloo ndawo apho ubomi bunokubakho kwaye bunamanzi, kodwa ngoku kufunyenwe nje ukuba, kuyabonakala ukuba, enye yezi zijikelezi-langa inesiseko sesinyithi, into esisiseko kubukho bobomi.
I-TRAPPIST-1 iqulethe iplanethi enesiseko esixineneyo, uphawu olubalulekileyo ukuze lube nakho ukubamba ubomi
Phakathi kokuncinci esikwaziyo malunga ne-TRAPPIST-1 namhlanje, sikuxelele ukuba sithetha ngomdaka omdaka wohlobo M, inkwenkwezi ebingakhanyanga kunelanga lethu kwaye, ngenxa yoku, indawo ekuhlalwa kuyo isondele kakhulu yiyo. Ngokutsho kweengcali ezithile, kuyacaca ukuba inyani yokuba le ndawo yobomi isondele kakhulu elangeni ibangela iingxaki ezininzi ukuba zivele ukuze ubomi bubekho njengoko bunjalo ukudibanisa Amaza olwandle, isiphumo esenza ukuba ixesha lokujikeleza kunye nokuguqulela lilingane, oko kuthetha ukuba omabini amacala eplanethi aboniswe ngokusisigxina kweli langa. Enye ingxaki enkulu inento yokwenza nokusondela kwenye yezi zijikelezi langa nelanga kunye ne amaqondo obushushu angaphezulu komhlaba.
Ngenxa yezi ngxaki, phakathi kwezinye, abaphandi abasebenza kuphando kunye nokwenziwa kwe-TRAPPIST-1 bagqibe kwelokuba bajonge kwinto abakholelwa ukuba ziiplanethi ezimbini ezinikezela ngobude bexesha lokuphila, TRAPPIST-1d kunye ne-TRAPPIST-1e. Kude kube namhla, zonke izifundo ezenziwayo kwezi planethi zijolise ekubeni nako Fumanisa ukuba kwezi planethi zimbini zinomazibuthe enamandla ngokwaneleyo ukuba angasebenza njengekhaka lokhuselo ngokuchasene nemitha ekhutshwa yinkwenkwezi ezijikeleza kuyo, kwaye ngenxa yoku kufuneka babenendawo engqindilili.
Ngexesha lophando lwamva nje oluqhutywa kwezi planethi zikhankanywe ngentla, iqela leenkwenkwezi kwiYunivesithi yaseColumbia liye lagqiba ukuba i-TRAPPIST-1e inesiseko esinyeneyo mhlawumbi iqulunqwe ngezinto zentsimbi ezifanayo kakhulu, ke ngoko, kumbindi woMhlaba. Lo mqobo ungayinjini yemagnetosphere enamandla enamandla eya kuthi ikhusele umphezulu we-TRAPPIST-1e kwimitha yelanga ekhutshwe yinkwenkwezi ejikelezayo.
Inzululwazi ngeenkwenkwezi inokwazi njani ukuba ingaba i-exoplanet inentsimbi engathi yeyomhlaba kumgama weminyaka engama-39 yokukhanya?
Ngale nto ndingathanda ukukhankanya amagama ezazi ngeenkwenkwezi UGabrielle Englemenn-Suissa y UDavid kipping:
Ukuba uyabazi ubunzima kunye nomyinge weplanethi ngokuchanekileyo, njengenkqubo ye-TRAPPIST-1, unokuthelekisa loo datha kunye neemodeli zethiyori yesakhiwo sangaphakathi. Ingxaki kukuba ezo modeli zihlala zineendlela ezine ezinokubakho: isiseko sesinyithi, ingubo yesilicate, umaleko wamanzi, kunye nemvulophu yokukhanya eguqukayo. Umhlaba uneeyokuqala ezimbini kuphela, iatmosfera yayo ayinalo igalelo kubunzima okanye irediyasi. Ngamanye amagama, sinezinto ezingaziwayo ezine kwaye zimbini kuphela izinto ezaziwayo eziguqukayo. Ngokomgaqo, yingxaki engenakusombululeka.
Endaweni yokuba sikhethe enye indlela yokuyibala. Siqala kwinto yokunikwa kobunzima kunye nerediyasi, azinakubakho iimodeli ezinenuclei encinci kune-X echaza ubunzima obubonwayo kunye nerediyasi. I-nucleus inokuba nkulu kune-X, kodwa ubuncinci kufuneka ibe ngu-X, kuba akukho modeli ithiyori inokuyichaza ngenye indlela. Umahluko u-X uhambelana nento esinokuyibiza ngokuba liqhezu le-radius esembindini. Ke sidlala umdlalo ofanayo ukufumanisa owona mda uphezulu.
