Soo koob maqaalka:  Qaar badan oo ka mid ah meerayaasha laga helay meel kale oo xidigaheena kamid ah uma eka dhulka, waxayse umuuqdaan meerayaasha Jupiter. Qorraxyadaas gaaska leh, ilaa inta aan ognahay, kuma haboona inay nolol ku noolaato, laakiin hadda waxaa la soo jeediyay in dayaxyada meerayaashaasi ay noqon karaan kuwo la noolaan karo. Haddii la xaqiijiyo, waxay soo jeedin kartaa in meelahaasi ay noqon karaan ilaha ugu badan ee nolosha ee koonkan, ma ahan aduunyo sida dhulkeena oo kale. Fikradda waxaa ka hadlay Dr Sarah Ballard oo ka tirsan Jaamacadda Washington ee Seattle, barnaamijka Raadiyaha Dadweynaha ee Caalamiga ah (PRI) ee The Takeaway. Hoos u dhaji si aad u maqasho codka. Dr. Sarah Ballard oo ka tirsan Jaamacadda Washington ayaa la hadlaysay PRI. Waxay sheegtay in exomoons ay noqon karaan'meelaha ugu badan ee nolosha ee caalamka'. Sawirka hoos ku qoran waa sawirka Upsilon Andromedae d, oo ah adduun weyn oo meel fog ku yaal, oo ku wareegsan gaaska weyn ee hore, kaas oo laga yaabo inuu leeyahay dayaxyo la degganaan karo. Waxay sharaxday sida meerayaasha cabirkooda ay u ekaan karaan meerayaasha Jupiter ee ku yaalla goobaha lagu noolaan karo ee xiddigaha - meelahaasoo ay xaaladuhu ku habboon yihiin biyaha, iyo malaha nolosha - ay uga badan yihiin meelaha dhagaxyada leh sida dhulka. Dayaxyo kale oo kulul. Xiddigaha iyo dayaxyada ka baxsan dhulka oo aad ugu dhow waxay yeelan karaan heerkul ka sareeya heerka biyaha ay karkarayaan, taas oo ka dhigaysa mid aan habbooneyn nolol kasta. Dayaxyo kale oo la degaan karo. Exoplanets-ka ku wareega aagagga la degaan karo ee nidaamka (halka biyaha dareeraha ah ay ku sii jiri karaan dusha sare ee meeraha) wali waxay u baahan yihiin culeys ku filan si ay u qabsadaan jawiga nidaamiya heerkulkooda. Haddii shuruudahaas la buuxiyo, rajada nolosha waa mid rajo leh. Dayaxyada soo baxa ee barafka cad. Dayaxyada ka sameysma meelo ka baxsan nidaamka qoraxda ee shisheeyaha ah waxaa laga yaabaa in ay ku badan yihiin baraf. Waxay ku sii jiri doonaan baraf qoto dheer haddii aysan kululeyn duufaanta ka imaaneysa meerahooda - mar kale uma badna inay noqon karaan deegaan nololeed. Dayaxyo ka baxsan dhulka oo socda. Dayaxyada meeraha leh meelaha ku wareegsan ee loo yaqaano elliptical waxay noqon karaan kuwo la noolaan karo inta badan sanadka meerahooda, laakiin waxay la kulmi karaan xilliyo kulul ama baraf baraf ah markay u soo dhowaadaan xiddigooda, ama aad uga fogaadaan kuleylka nolosha siiya. Waxaa laga soo xigtay majaladda All About Space. Haddii xitaa qaar kamid ah...
Dr. Sarah Ballard oo ka tirsan Jaamacadda Washington ayaa la hadlaysay PRI. Waxay sheegtay in dayaxyada ka baxsan meeraha ay noqon karaan meelaha ugu badan ee noloshu ku jirto caalamka Qaar badan oo ka mid ah meerayaasha laga helay meelaha ka baxsan nidaamka qorraxda waxay la egyihiin meeraha Jupiter. Waxay tusineysaa in meelaha la degaan karo ee dhulka la midka ah aysan sidaa u badneyn. Taa badalkeed, dayaxyada ku wareega meerayaasha waawayn ayaa noqon kara meesha ugu wanaagsan ee nolosha laga heli karo.
