Kwenzekile: ubuntu, okanye ngakumbi, I-NASA ayifumananga ngaphezulu okanye ngaphantsi kweeplanethi ezisixhenxe ezinamatye ngokufanayo noMhlaba, Oko kunokuthetha ukuba ezinye zazo zinokuba namanzi angamanzi kwaye, ngubani owaziyo, mhlawumbi ubomi.
Ukufumanisa, ngaphandle kwamathandabuzo, yenye yezona zinto zibalulekileyo kwimbali yethu yamva nje, ukusukela ngoku kunanini na ngaphambili singasondela ekwazini ukuba sisedwa kwiNdalo iphela okanye ukuba sabelana ngayo nabanye abantu.
NgoLwesithathu, nge-22 kaFebruwari 2017, enye yeeteleskopu zeNASA yafumanisa inkqubo yelanga eneeplanethi ezisixhenxe ezinamatye. Inkwenkwezi ejikeleza kuyo "ibhaptizwe" UMNTU-1, kunye neeplanethi njenge b, c, d, e, f, g, h. Ezi globhu ezinamatye, nangona bengakhange bazibone ngqo, Izazinzulu zibubonile ubukho bayo kubungakanani bayo kunye nobunzima bayo ngokuhla kweenkwenkwezi ngalo lonke ixesha xa enye yeenkwenkwezi isiza phakathi kwawo noMhlaba..
Kwizinto ezintathu kubo -e, f, g- kungakho ubomi xa bekwindawo yokuhlala yenkwenkweziOko kukuthi, apho ubushushu banele khona ukuze kubekho amanzi angamanzi. Iiplanethi b, c, kunye no-d zisondele kakhulu kwinkwenkwezi, ke kusenokwenzeka ukuba kushushu kakhulu, kwaye iplanethi h, eyiyeyona ikude, inokubanda kakhulu. Okwangoku, izazinzulu azikhuphi mthetho: UMichaël Gillon we-NASA uthe »kunokubakho amanzi nakweyiphi na kuzo».

Le Solar System ibekwe kwizigidi ezingama-40 zeminyaka yokukhanya ukusuka eMhlabeni, kwikroza le-Aquarius, kunye yiplanethi f oyena mgqatswa ubalaseleyo wokubamba ubomi. Iyafana ngobukhulu kwiplanethi yethu kwaye ithatha iintsuku ezilithoba ukujikeleza inkwenkwezi yayo. Ke, akukho nto ayenzileyo ngaphandle kokubhabha. Inokuba kunjani ukuhlala apho?
U-Amaury Triaud, umbhali-mbhali wophando, waseCambridge Institute of Astronomy (UK) uthe "ukubakhona emini kuya kufana nalapha ukutshona kwelanga. Ingayinto entle kuba rhoqo rhoqo enye iplanethi yayiza kudlula esibhakabhakeni eyayinokubonakala iphindwe kabini njengenyanga». Nangona kunjalo, unyaka womhlaba ungathatha iintsuku ezilithoba, kwaye sisistim elanga sinokuthi "yipokotho".
Inkwenkwezi i-Trappist-1 yinto encinci ye-ultracold ene-radius elingana ne-12% yeLanga kunye nobushushu bomhlaba obumalunga ne-2300ºC, xa kuthelekiswa ne-5500ºC yenkosi yethu yenkwenkwezi. Ngesi sizathu, iqondo lobushushu kumphezulu weplanethi f mhlawumbi ngamanqanaba aliqela asezantsi kunalapha (14-15 ° C).
Nangona konke, kuphela kwento enobunzima obaneleyo ukugcina imeko-bume, eziyimfuneko ebomini.
