<prompt> Fingqa isihloko: Njengoba sithola izinhlelo eziningi zamaplanethi kwenye indawo emthaleni wethu, kunento edida izazi zezinkanyezi - kungani isimiso sethu sonozungezilanga sibonakala sihlukile kangaka? Ezinye izinhlelo eziningi zinama - Super-Earth namanye amaplanethi asezindaweni ezizungeza izinkanyezi zawo, kodwa ezethu azinawo. Futhi manje singase sazi ukuthi kungani - ngoba iJupiter yayisebenza njengebhola elibhidlizayo ekuqaleni kwesimiso sonozungezilanga futhi yayishaya amaplanethi aphume esimisweni sonozungezilanga noma ayibuyisele endaweni yawo. Ososayensi base-University of California baye banikeza inkolelo-mbono entsha yesimiso sonozungezilanga. Bathi ekuqaleni kokuphila kwayo, iJupiter yayizulazula phakathi kwamaplanethi angaphakathi kuboniswa umfanekiso wesimiso sonozungezilanga sasekuqaleni. Lokhu kuchaza ukuthi kungani zingekho amaplanethi phakathi kukaMercury nelanga. Kodwa kungase futhi kubonise ukuthi isimiso sethusiyinqabaemthaleni. Uma lokhu kuyiqiniso, kungasho ukuthi izimo eziye zavumela ukuphila ukuba kuchume eMhlabeni azivamile neze. Lolu cwaningo olwanyatheliswa kuyi - Proceedings of the National Academy of Sciences lusiza ekuchazeni ukuthi kungani isimiso sethu sonozungezilanga sihluke kakhulu emakhulwini ezinye isimiso ezatholwa eminyakeni yamuva. Manje sesingabheka isimiso sethu sonozungezilanga esimweni sazo zonke lezi ezinye izinhlelo zamaplanethi, esinye sezici ezithakazelisa kakhulu ukungabikho kwamaplanethi ngaphakathi komjikelezo kaMercury,kusho uProfesa Gregory Laughlin, waseCalifornia University eSanta Cruz, ongumbhali wocwaningo. Uhlelo olujwayelekile lwamaplanethi emthaleni wethu lubonakala luyiqoqo leMihlaba emikhulu enezikhathi zokuzungeza ezimfushane ngokushaqisayo. Isimiso sethu sonozungezilanga siya ngokuya sibonakala siyinqaba. Abezizwe bangempela - hhayi amadoda amancane aluhlaza avakashela uMhlaba njengoba kuboniswa emabhayisikobho, kodwa kunalokho ukuphila kwamagciwane esimisweni sethu sonozungezilanga nokuphila okuhlakaniphile okungale kwalokho. Lokhu ngokusho kwabacwaningi ababili abaphambili be-Search for Extraterrestrial Intelligence SETI, abahlanganyela ekulalelweni kweKomiti YeNdlu Yezigele Yezesayensi, Isikhala, Nobuchwepheshe eWashington DC ngo-August odlule. Enkulumweni eyayinesihloko esithi I - Astrobiology Nokufuna Ukuphila Emkhathini ngo - May, ososayensi babeka ubufakazi nezizathu zokukholelwa ukuthi asisodwa...  <response>: IYunivesithi yaseCalifornia inikeze umbono omusha ngesimiso sonozungezilanga. Bathi ekuqaleni kokuphila kwayo, iJupiter yahamba phakathi kwamaplanethi angaphakathi. Lokhu kuchaza ukuthi kungani zingekho amaplanethi phakathi kukaMercury nelanga. Kodwa kungase futhi kubonise ukuthi isimiso sethusiyinqabaemthaleni. Futhi kungase kusho ukuthi izimo zokuphila eMhlabeni zazimbi kakhulu.
