10 amathuba amatsha obomi basemzini

Kumashumi eminyaka, endaweni yokuxhalaba ngakumbi ngokugcina iplanethi esihlala kuyo kwiimeko ezifanelekileyo, isayensi ikhethile jonga amanye amazwe apho ubomi bunokwenzeka khona, nokuba ziiplanethi ezingenanto abantu abanokuhlala kuzo (kwaye bazixhaphaze), okanye iiplanethi ezigcina ubomi bangaphandle kwaye esinokoyisa.

Ngo-2009, i-NASA's Kepler space mission yaqala ngenjongo yokuphendula kakhulu Cacisa: "Zingaphi iiplanethi ezifanayo neplanethi yoMhlaba ezikhoyo kumnyele?" Emva kweminyaka esibhozo yophando, sele sinayo impendulo yokuqala.

Iiplanethi ezilishumi zafunyanwa ukujonga ubomi

Iqela elikhethekileyo le-Kepler ye-space mission, emva kweminyaka esibhozo yokusebenza nzima, sele ivelisile ukuba yeyiphi, okomzuzwana nje ikhathalogu enkulu isakhono iiplanethi ezintsha. Ngokukodwa, olu luhlu lwenziwe zizonke Iziphumo ezingama-219, kodwa ayizizo zonke ezisemthethweni ukubamba ubomi.

Kuzo zonke ezi zinto zifunyanisiweyo, zilishumi kuzo zinobukhulu obufanayo kakhulu nobukhulu beplanethi yethu enguMhlaba, ukongeza ekubeni ne-orbit efanayo. Yintoni egqithisile, inokuphila Ngelixa zikwindawo ebizwa ngokuba "yindawo yokuhlala", oko kukuthi, zikude ngokwaneleyo kude neLanga ukufaka amanzi kwindawo engamanzi, ebalulekileyo ebomini.

UMario Pérez, ilungu le-Kepler mission ye-NASA ye-Astrophysics Division, wayephethe uxanduva lokwenza uluntu olu lwazi Nje izolo ukusuka eSilicon Valley. Ngezi ziphumo zingama-219, sele zilungile Kufunyenwe abagqatswa abangama-4.034. Kuzo zonke, sele kuqinisekisiwe ukuba i-2.335 ingaphandle kwesixokelelwano sethu selanga (ke ngoko, zizi-exoplanets), ngelixa zingamashumi amathathu zisondele kwiplanethi yethu.

Njengoko unokucinga, isathelayithi eyenziweyo UKepler uyaqhubeka nokujikeleza iLanga ukuze azalisekise injongo yakhe yokukhangela iiplanethi ezintsha ezinokubamba ubomi Ukutyhila idatha entsha kunye nolwazi olusivumela ukuba siyiqonde ngcono iNdalo.
