<prompt> Fingqa isihloko: Ososayensi abasebenzisa i - Hubble Space Telescope baye baqinisekisa ukuthi. Inyanga kaJupiter iGanymede inolwandle ngaphansi kobuso bayo obuneqhwa, okwandisa amathuba okuphila, kwembule iNasa. Lokhu okutholakele kuxazulula imfihlakalo ephathelene nenyanga enkulu kunazo zonke ohlelweni lwelanga ngemva kokuba umkhumbi-mkhathi we-NASA i-Galileo, manje ongasekho, unikeze izinkomba zokuthi iGanymede inolwandle olungaphansi komhlaba phakathi nokuhlolwa kweJupiter nezinkanyezi zayo kusukela ngo-1995 kuya ku-2003. Ososayensi batshela izintatheli engqungqutheleni yocingo ukuthi kwadingeka umsebenzi othile wokuphenya ukuze kuqinisekiswe lokhu okutholakele. Kulo mbono womculi, inyanga uGanymede izungeza iplanethi enkulu iJupiter. Ulwandle olunosawoti ngaphansi kweqhwa lenyanga yilona oluchaza kangcono ukushintsha kwamabhande e-aurora alinganiswe i-Hubble. Ososayensi baqala ukusola ukuthi kunolwandle eGanymede ngawo-1970, besebenzisa imodeli yenyanga enkulu. Ngo - 2002, ithimba le - NASA i - Galileo lalinganisa amandla kazibuthe kaGanymede, laletha ubufakazi bokuqala obusekela lokho okusolwa. Umkhumbi-mkhathi i-Galileo wathatha izilinganiso ezimfushane zesithombe esifushane somkhakha kazibuthe ngezikhathi zemizuzu engu-20, kodwa ukuhlola kwawo kwakukufushane kakhulu ukuba kubambe ngokucacile ukuzamazama komkhakha wesibili kazibuthe wasolwandle. Njengomhlaba, iGanymede inenhliziyo yensimbi ewuketshezi ekhiqiza. magnetic field, nakuba inkambu kaGanymede ifakwe ngaphakathi. Inkambu kazibuthe kaJupiter. Lokho kubeka isisekelo esithakazelisayo sokusebenzelana nemibono ebonakalayo - amabhendi amabili ama-aurora akhanyayo azungezile. Izindawo ezisenkabazwe esenyakatho neseningizimu yeGanymede. Njengoba iJupiter ijikeleza, amandla ayo kazibuthe ayashintsha, abangele. I-aurora kaGanymedes iyashintsha. Ososayensi balinganisa ukunyakaza futhi bathola ukuthi kwakungafinyeleleki. Besebenzisa imodeli ye - computer, baqaphela ukuthi ulwandle olunosawoti, oluqhuba ugesi ngaphansi kwenyanga lwaluvimbela amandla kaJupiter okudonsa. IJupiter injengendlu yesibani enensimu yamagnetic eguqukayo ngokujikeleza kwendlu yesibani. Ithonya i-aurora, kusho isazi se-geophysicist uJoachim Saur, ne-University of Cologne eJalimane. Njengoba ulwandle lusondela, ukuzamazama kuncipha ngokuphawulekayo. Ososayensi bahamba ngaphezulu...  <response>: Ukutholakala kwayo kuxazulula imfihlakalo mayelana nenyanga enkulu kunazo zonke ohlelweni lwelanga. I - Hubble Space Telescope yaqinisekisa ukuthi inyanga ezungeza iJupiter inolwandle.
