Ingcamango yomculi ibonisa iplanethi efana nomhlaba uKepler-452b (i-NASA Ames / JPL-Caltech / T. Pyle) IZiko le-SETI kunye ne-NASA bakuqinisekisile ukufunyanwa kwe-Kepler 452b, oyena mhlaba ufana noMhlaba. Ifumaneka kwindawo ye-Goldilocks yenkwenkwezi yayo, le planethi iya kuba neemeko ezifanelekileyo zokuxhasa amanzi alulwelo kwaye mhlawumbi nobomi. Eli hlabathi lingaqhelekanga labonwa yi-Kepler Space Telescope kwaye yiplanethi yokuqala eqinisekisiweyo phakathi kwama-500 abagqatswa abanokubakho kwimishini ikhathalogu .
U-Kepler 452b usisondeza kwinyathelo elinye ekusondeleni ekuqondeni ukuba zingaphi iiplanethi ezinokuhlala ezilapha, utshilo uJoseph Twicken, umphathi we-SETI ongumkhokeli wenkqubo yezenzululwazi ye-Kepler mission.
Iplanethi i-1,400 ukukhanya-iminyaka yokukhanya ukusuka kwiNkqubo yethu yeSolar kwaye ijikeleza iinkwenkwezi zeenkwenkwezi zibiza umzala wethu weLanga. Ngelixa le nkwenkwezi ineepesenti ezine ngaphezulu kwaye ishumi leepesenti likhanya ngakumbi, umgama phakathi kwayo neKepler 452b ulingana ngokufanayo nomgama woMhlaba ukusuka eLangeni. Iplanethi yona ineradiyo engama-60 epesenti enkulu kunoMhlaba kwaye ikrokrelwa ukuba inamatye, inomoya oxineneyo kunye nesixa esikhulu samanzi.
Inkwenkwezi ye-Kepler 452b ye-host is 1.5 yezigidigidi zeminyaka indala kuneyethu, kwaye iya kunika izazinzulu umbono wendlela yobudala beLanga obuya kuthi ekugqibeleni buchaphazele ngayo uMhlaba. Amandla akhulayo avela elangeni eligugileyo anokufudumeza umphezulu kwaye abe ngumphunga nawuphi na ulwandle. Umphunga wamanzi uza kulahleka emhlabeni ngonaphakade, utshilo u-Doug Caldwell, isazinzulu se-SETI esabelwe umsebenzi we-Kepler. I-Kepler 452b isenokuba namava ngoku okuya kwenzeka kuMhlaba ngaphezulu kwewaka leminyaka ukusukela ngoku, njengoko iLanga liguga kwaye likhula likhanya ngakumbi.

Yasungulwa kwiminyaka esithoba eyadlulayo, iThe Kepler Space Telescope ichonga iiplanethi ezinokubakho ngokusebenzisa ‘indlela yokuhamba’ yokujonga ukukhanya okufiphala rhoqo kweenkwenkwezi kwindlela yazo. Siyazi ngokuqinisekileyo ukuba zintathu iintlobo ze-exoplanets ezilahla umnyele: ii-ice giants, iigesi ezinkulu kunye ne-super-Earths ezishushu. Umceli mngeni we-Kepler's mission kukufumana iiplanethi zomhlaba ezisisiqingatha ukuya kumaxesha amabini ubukhulu bomhlaba. Eyona njongo iphambili kukufumanisa ipesenti yamakhulu ezigidi zeenkwenkwezi ezinokuba likhaya kwilizwe elinje.
U-Kepler sele echonge ngaphezulu kwe-exoplanets ukusukela ekuqaleni kohambo lwayo, ngokulinganisa ubunzulu 'bokuhamba' kunye nobukhulu beenkwenkwezi zabo. Iqondo lobushushu eliphakathi kwiplanethi linokubalwa kusetyenziswa umgama wokujikeleza kunye nobushushu benkwenkwezi. Lo ngumlinganiso omiselweyo xa uhlela i-exoplanet njengendawo ekuhlalwa kuyo. Phambi kwesibhengezo sanamhlanje, ezona planethi zimbini zifana noMhlaba ezifunyenweyo yayinguKepler 438b noKepler 442b, amakhulu kunoMhlaba kwaye ajikeleza abomvu abancinci-iinkwenkwezi ezipholileyo kakhulu kuneLanga.
I-Exoplanets, ngakumbi umhlaba omncinci wobungakanani bomhlaba, yayingowombuso wentsomi kwiminyaka engama-21 eyadlulayo. Namhlanje, kunye namawaka okufumanisa kamva, izazi ngeenkwenkwezi zikwinqanaba lokufumana into abantu abaphuphe ngayo amawaka eminyaka - omnye uMhlaba, wahlekisa nge-NASA ngaphambi kwenkomfa yabezindaba yanamhlanje.
