Kutshanje, bekuya kubonakala kumangalisa ukuba izazi ngeenkwenkwezi zinokusebenzisa iiteleskopu ukujonga iiplanethi ezijikeleze iinkwenkwezi kumakhulu eminyaka yokukhanya kude nenkqubo yethu. Kodwa oku kunjalo, apho iiteleskopu zasemajukujukwini ezifakwe kwi-orbit zanceda kakhulu. Ngokukodwa, i-mission ye-Kepler, engaphezulu kweminyaka elishumi yomsebenzi iqokelele isiseko samawaka eexoplanets. Ezi vimba zisafuna ukuphononongwa kwaye zifundwe, kunye neendlela ezintsha zokuhlalutya fumanisa izinto ezinomdla.
Ngokomzekelo, kwinqaku lakutshanje kwimpapasho Iqela lezazinzulu ezivela kwiYunivesithi yaseWashington State lichaze ukukhethwa kwee-exoplanets ezingama-24, iimeko zokuphila ezinokuthi zithandeke ngakumbi kunoMhlaba. Ii-exoplanets zakhethwa kwi-database ye-Kepler orbital telescope mission, ebizwa ngokuba yi-exoplanets. , xa iplanethi ifunyenwe ngelixa idlula kwidiski yomzali wayo inkwenkwezi.
Kodwa ngaphambi kokuba bakhangele βiiparadesiβ ezingaphandle komhlaba, izazinzulu zaseka iindlela ekuza kwenziwa ngazo ukhetho olutsha. Ke, ukongeza ekukhangeleni ii-exoplanets kwindawo ekunokuhlalwa kuyo yeenkwenkwezi, apho amanzi angamanzi anokuhlala kwiplanethi enamatye kwaye angabi ngumkhenkce okanye abilise, uninzi lwezinye ezintsha zongezwa kwizinto zokukhangela. Okokuqala, kucetywa ukuba kukhangelwe ii-exoplanets kwiinkqubo zeenkwenkwezi ezincinci kancinci kuneLanga, ezizezalo. (Ilanga yiklasi G). Abancinci bohlobo lwe-K abashushu kancinci baphila ukuya kutsho kuma-70 eebhiliyoni zeminyaka, ngelixa iinkwenkwezi zodidi lwe-G azihlali xesha lide kwaye ziphila malunga ne-10 leminyaka yeebhiliyoni. Indlela engama-70 eebhiliyoni ubude inokunika ubomi ithuba elingcono lokuphuhla kunendlela emfutshane ephindwe kasixhenxe.
Okwesibini, i-exoplanet enkulu kancinci kunoMhlaba, yithi i-10% enkulu, ingabonelela ngommandla wobomi. Okwesithathu, i-exoplanet enkulu ngakumbi, ubukhulu becala elinye nesiqingatha kunoMhlaba, inokugcina i-atmosfera ixesha elide kwaye, ngenxa yombindi osebenzayo kunye nomkhulu, inokugcina ubushushu ixesha elide. Kukwasebenza okufanayo kwintsimi ye-electromagnetic, ekukholelwa ukuba ubukhulu becala kungenxa ye-nucleus. Okwesine, ukuba i-avareji yobushushu bonyaka kwi-exoplanet ibingu-5Β°C ngaphezulu kunoMhlaba, oku kuya kuba nefuthe elihle kwizinto eziphilayo.
Ngokubanzi, akukho namnye kubaviwa be-24 be-exoplanet kwindima "yeparadesi" onokuziqhayisa ngayo yonke into eyinkimbinkimbi yezinto ezibangela uqhushululu lobomi, kodwa enye yazo iyanelisa imilinganiselo emine ngaxeshanye. Ke, izazinzulu ziye zakhetha ekujoliswe kuzo kuphononongo olusondeleyo lwabaviwa bobomi bangaphandle. Kodwa amandla kunye neendlela zenzululwazi azipheli. Akunakwenzeka ngaphandle kwenjongo.
