<prompt> Fingqa isihloko: Izazi zezinkanyezi zikholelwa ukuthi imibiko engaqondakali - ngaphambili eyayibhekwa njengokuqhuma kwezinkanyezi - ivela kuyiplanethi efana noMhlaba. Iplanethi iGliese 581d inezimo ezingase zisekele ukuphila, futhi cishe iyiplanethi enamadwala, amakhulu ngokuphindwe kabili kunawoMhlaba. Izimpawu ezivela kule planethi ekuqaleni zatholakala ngo-2010, kodwa ngonyaka odlule zathathwa njengomsindo ovela ezinkanyezini ezikude. Skrolela phansi ukuze ubone ividiyo. Izazi zezinkanyezi zikholelwa ukuthi izibonakaliso ezingaqondakali ezivela kwezinye izidalwa - ngaphambili ezazibhekwa njengokuqhuma kwezinkanyezi - empeleni zivela kuyiplanethi efana noMhlaba. Iplanethi iGliese 581d yaqala ukutholwa ngo-2010 umbono womculi osesithombeni Manje, olunye ucwaningo luthi ucwaningo lwango-2014 lwalusekelwe kuhlaziywa okunganele kwedatha nokuthi iGliese 581d ikhona. Le planethi yatholakala okokuqala ngo-2010. Kwakuyiplanethi yokuqala efana noMhlaba eyatholakala endaweni ebizwa ngokuthi iGoldilocks ezungeze enye inkanyezi. Kodwa ngokushesha ngemva kwalokhu kutholakala, iqembu lososayensi lathi lezi zimpawu okwakuthiwa zivela kuyiplanethi empeleni zazimane nje ziyizikhukhula zamandla kazibuthe ezivela ezinkanyezini. Lolu cwaningo lwakamuva luthi ucwaningo lwezinkanyezi eziqhumayo lwalusekelwe ekuhlaziyweni okunganele kwedatha. Bathi le ndlela ilungele amaplanethi amakhulu, kodwa le ndlela ayikwazi ukuthola amaplanethi amancane afana ne-GJ 581d. Ngonyaka odlule, abacwaningi basePennsylvania State University bathi iGliese 581d - nomngane wayo iGliese 581g - kumane nje kuwumkhonyovu wokukhanya obangelwa ukuqhuma kukagesi okuvela enkanyezini yendawo ekude ngeminyaka yokukhanya engu - 22. Nokho, ucwaningo olusha lwaseBrithani, luthi indlela esetshenziswe iqembu lasePennsylvania yayilungele amaplanethi amakhulu kuphela, futhi yayingase ingawanaki amancane anjenge-GJ 581d. Lolu cwaningo, olwenziwe i-Queen Mary University, eLondon ne-University of Hertfordshire, luthi lusebenzisa imodeli enembe kakhudlwana kulwazi olukhona. Ukuba khona noma ukungabi khona kwe-GJ 581d kubalulekile ngoba kwakuyiplanethi yokuqala efana noMhlaba eyatholakala endaweni ebizwa ngokuthi i-Goldilocks ezungeze enye inkanyezi futhi iyisibonelo esivelele sokusetshenziswa kobuchwepheshe be-Doppler, kusho umbhali oholayo, uDkt. Guillem Anglada-Escudé. Kuhlale kunezingxoxo phakathi kososayensi mayelana...  <response>: I-Gliese 581d isendaweni enabantu futhi ingase ilungele abantu. Latholwa ngo-2010, kamuva lakhishwa njengokuqhuma kwezinkanyezi hhayi iplanethi. Manje, ososayensi bakholelwa ukuthi ukuhlaziywa kwangaphambilini kwakusekelwe emininingwaneni engalungile. Bathi iplanethi ikhona futhi ingase inikeze ithemba lokuthola ukuphila kwamanye amazwe.
