Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Jirgin ruwan Galilean mai sanyi, Europa, Ganymede da Callisto, duk suna haifar da lokutan magnetic da aka haifar don amsawa ga canje-canje a cikin filin magnetic na Jupiter. Waɗannan lokutan magnetic masu canzawa suna haifar da filayen magnetic dipole a kusa da su, waɗanda ke aiki don rama canje-canje a cikin filin kewaye. An yi imanin cewa shigarwar tana faruwa ne a cikin ɗakunan ruwa mai gishiri, wanda wataƙila ya wanzu a cikin dukkan manyan watannin Jupiter. Wadannan tekuna na karkashin kasa na iya samun damar rayuwa, kuma shaidar kasancewar su na daya daga cikin mahimman abubuwan da aka gano a cikin shekarun 1990 ta hanyar sararin samaniya. Hadin gwiwar magnetosphere na Jovian tare da Ganymede, wanda ke da mahimmancin magnetic, ya bambanta da hulɗarsa da watannin da ba magnetized ba. Filin Magnetic na ciki na Ganymede ya sassaƙa rami a cikin magnetosphere na Jupiter tare da diamita na kusan diamita biyu na Ganymede, yana ƙirƙirar ƙaramin magnetosphere a cikin magnetosphere na Jupiter. Filin maganadisu na Ganymede ya karkatar da kwararar plasma mai juyawa a kusa da magnetosphere. Hakanan yana kare yankuna masu tsaka-tsakin wata, inda layukan filin suka rufe, daga barbashi mai kuzari. Na biyun har yanzu yana iya buga sandunan Ganymede kyauta, inda layin filin yake a buɗe. Wasu daga cikin barbashi masu kuzari sun makale a kusa da equator na Ganymede, suna samar da kananan belts radiation. Lantarki masu kuzari da ke shiga cikin yanayinta na bakin ciki suna da alhakin lura da Ganymedian polar aurorae. Chargedararrun abubuwa suna da tasiri mai yawa a kan kaddarorin farfajiyar watannin Galileo. Plasma da aka samo daga Io yana ɗaukar sulfur da sodium ions nesa da duniyar tamu, inda aka dasa su da fifiko a kan hemispheres na Europa da Ganymede. A kan Callisto, duk da haka, saboda dalilai da ba a sani ba, sulfur yana mai da hankali a cikin hemisphere na gaba. Plasma na iya zama alhakin duhu na ƙarshen watanni (sake, ban da Callisto).
