Kusukela ukutholakala kobukhona be UTHANDO-1 Kube nezindaba eziningi esezifinyelele kithi mayelana nokuthi kungenzeka ukuthi kube khona uhlobo oluthile lokuphila kulo, ngenxa ye-morphology yalo, yize, kungekudala nje, zonke lezi zinkomba, ukubabiza ngandlela thile, ziye zaboniswa kancane kancane akulona iqiniso ngokwanele noma, ngemuva kophenyo oluhlukile, kukhonjisiwe ukuthi ngeke banikezwe.
Noma kunjalo, namuhla ngifuna ukukutshela ngokutholwa okusha okungaba izindaba ezinhle. Ngokusho kwezazi ezahlukene nabaphenyi abangongoti, ngokusobala lolu hlelo lwelanga etholakala eminyakeni engaphansi kwengu-39 yokukhanya ukusuka eMhlabeni, ayiqukethe kuphela amaplanethi atholakala kuleyo ndawo lapho impilo ingaba khona futhi ibe namanzi, kodwa manje sekutholakele ukuthi, ngokusobala, elinye lala maplanethi linengqikithi yensimbi, imfuneko eyisisekelo yokuba khona kwempilo.
I-TRAPPIST-1 iqukethe iplanethi enomnyombo ominyene, isici esibalulekile ukuze sikwazi ukusingatha impilo
Phakathi kokuncane esikwaziyo ngo-TRAPPIST-1 namuhla, ngikutshele ukuthi sikhuluma ngomuntu onsundu wohlobo M, inkanyezi ebingakhanyi kakhulu kunelanga lethu nokuthi, ngenxa yalokhu, indawo yayo yokuhlala isondele kakhulu it. Ngokusho kochwepheshe abathile, ngokusobala iqiniso lokuthi le ndawo yokuphila isondele kakhulu elangeni lidala izinkinga eziningi ukuvela ukuze impilo ibekhona njengoba injalo ukuhlanganisa amagagasi, umphumela owenza izinkathi zokujikeleza nokuhumusha zilingane, okusho ukuthi zombili izinhlangothi zeplanethi zivezwe unomphela kuleli langa. Enye inkinga enkulu iphathelene nokusondela kweplanethi ngayinye yalezi langa kanye nelanga layo amazinga okushisa angaphezulu.
Ngokuqondile ngenxa yalezi zinkinga, phakathi kokunye, abacwaningi abasebenza ocwaningweni nasekwakhiweni kwe-TRAPPIST-1 banqume ukugxila kulokho abakholelwa ukuthi amaplanethi amabili anikeza isikhathi eside kakhulu sokuphila, i-TRAPPIST-1d ne-TRAPPIST-1e. Kuze kube manje, zonke izifundo ezenziwa kula maplanethi zihlose ukukwazi thola ukuthi ngabe lawa maplanethi amabili anawo yini uzibuthe enamandla ngokwanele ukuthi angasebenza njengesihlangu esivikelayo emisebeni ekhishwa yinkanyezi abayizungezayo futhi, ngenxa yalokhu, badinga ukuba nomnyombo ominyene.
Ngesikhathi kwenziwa ucwaningo lwakamuva emaplanethi ashiwo ngenhla, iqembu lezazi zezinkanyezi e-Columbia University lisanda kunquma ukuthi i-TRAPPIST-1e inomnyombo ominyene mhlawumbe yakhiwe ngezinto zensimbi ezifanayo kakhulu, ngakho-ke, kumongo woMhlaba. Lo mongo ungaba yimoto kazibuthe onamandla ozovikela indawo ye-TRAPPIST-1e emililweni yelanga ekhishwa yinkanyezi ezungeza yona.
Izazi zezinkanyezi zingazi kanjani ngokuqinisekile ukuthi i-exoplanet inomsuka wensimbi njengowomhlaba ebangeni leminyaka ekhanyayo engama-39?
Ngalokhu ngithanda ukusho amagama ezazi ngezinkanyezi UGabrielle Englemenn-Suissa y UDavid kipping:
Uma wazi ubukhulu nobubanzi beplanethi ngokunembile, njengoba kunjalo ngohlelo lwe-TRAPPIST-1, ungaqhathanisa leyo datha namamodeli we-theory yesakhiwo sangaphakathi. Inkinga ukuthi lawo amamodeli ngokuvamile aqukethe izingqimba ezine ezingaba khona: i-core core, ingubo yesilicate, ungqimba lwamanzi, nemvilophu elula elula. Umhlaba unezinto ezimbili zokuqala kuphela, umkhathi wawo awunikeli kakhulu kusisindo noma kwirejista. Ngamanye amagama, sinezinto ezine esingazazi kanye nezimbili eziguquguqukayo ezaziwayo. Empeleni, kuyinkinga engaxazululeki.
Esikhundleni salokho sikhetha enye indlela yokuyibala. Siqala kusukela kunikezwe ubukhulu nobubanzi, azikwazi ukuba khona amamodeli ane-nuclei encane kuno-X echaza ubukhulu obubonwayo nobubanzi. I-nucleus ingaba nkulu kune-X, kepha okungenani kufanele ibe ngu-X, ngoba ayikho imodeli yethiyori engayichaza ngenye indlela. Lokho kuhlukahluka kwe-X kufana nalokho esingakubiza ngengxenyana yengqikithi yobubanzi obuphakathi nendawo. Ngakho-ke sidlala lowo mdlalo ukuthola umkhawulo omkhulu.
