<prompt> Fingqa isihloko: Amaplanethi amaningi atholakala kwenye indawo emthaleni wethu awafani noMhlaba, kunalokho afana neJupiter. Ngokwazi kwethu, iziqhwaga ezinjengegesi ezinjalo azikufanelekeli ukuphila, kodwa manje kuye kwasikiselwa ukuthi izinyanga zalamaplanethi zingakufanelekela ukuphila. Uma lokhu kuqinisekiswa, kungasho ukuthi lezi zindawo zingaba imithombo eyinhloko yokuphila endaweni yonke, hhayi imihlaba efana nomhlaba wethu. Lo mbono waxoxwa nguDkt Sarah Ballard wase-University of Washington eSeattle, ohlelweni lwe-Public Radio International PRI i-The Takeaway. Skrolela phansi ukuze uthole umsindo. UDkt. Sarah Ballard waseYunivesithi yaseWashington wayekhuluma nePRI. Wathi ama-exomoon angaba izindawo ezivelele zokuphila endaweni yonke. Kuboniswe isithombe se - Upsilon Andromedae d, izwe elikhulu elikude, elizungeza i - gas giant ngaphambili, okungenzeka ukuthi linezinyanga ezihlala abantu. Wachaza ukuthi amaplanethi anobukhulu obufana nobukaJupiter asezindaweni ezihlala izinkanyezi - lapho izimo zilungele khona amanzi, futhi mhlawumbe nokuphila - avame kakhulu kunemihlaba enamadwala eyodwa efana noMhlaba. Izinyanga ezishisayo. Uma iseduze kakhulu nenkanyezi nenyanga engaphandle, ingaba nezinga lokushisa elingaphezu kokubilisa kwamanzi, okwenza ingafaneleki nganoma iluphi uhlobo lokuphila. Izinyanga ezingaphandle ezihlala abantu. Ama - exoplanet azungeza endaweni lapho kunendawo yokuhlala khona lapho amanzi angamanzi engahlala khona phezu kweplanethi asadinga amandla adonsela phansi anele ukuze abambe umoya ovumela izinga lokushisa kwawo. Nokho, uma kuhlangatshezwana nalezi zimfuneko, amathemba okuphila athembisa. Izinyanga ze-snowball exomoons. Kungenzeka ukuthi izinyanga ezakhiwe emaphethelweni angaphandle esimiso sonozungezilanga sangaphandle zigcwele iqhwa. Ziyohlala ziqandisiwe ngaphandle kokuba zifudunyezwe amagagasi avela eplanethini yazo - futhi akunakwenzeka ukuba zibe izindawo zokuphila. Ama-exomoon adlulayo. Izinyanga zamaplanethi anezindawo ezizungeza i-elliptical zingase zihlale isikhathi esiningi sonyaka weplanethi yazo, kodwa zingase zibe nezikhathi ezishisayo noma zeqhwa njengoba zisondela kakhulu enkanyezini yazo, noma zikude kakhulu nokushisa kwayo okunikeza ukuphila. Umthombo: Umagazini i - All About Space. Ngisho noma ezinye zalezi...  <response>: UDkt. Sarah Ballard waseNyuvesi yaseWashington wayekhuluma nePRI. Wathi ama-exomoon angaba izindawo ezivelele zokuphila endaweni yonke Amaplanethi amaningi atholakele ngaphandle kwesimiso sonozungezilanga ayizindawo ezinjengeJupiter. Kusikisela ukuthi amaplanethi anokuhlala afana noMhlaba kungenzeka awavamile kangako. Kunalokho, izinyanga ezizungeza amaplanethi amakhulu zingase zibe yindlela engcono kakhulu yokuphila.
