I-Jupiter indala kunawo wonke!

Kuvela ukuthi iplanethi endala kunazo zonke ohlelweni lwelanga yiJupiter. Lokhu kushiwo ososayensi baseLawrence Livermore National Laboratory kanye ne-Institute of Paleontology eNyuvesi yaseMunster. Ngokufunda ama-isotopes e-tungsten ne-molybdenum kuma-meteorite ensimbi, bafinyelela esiphethweni sokuthi avela kumaqoqo amabili ahlukene phakathi endaweni ethile phakathi kwesigidi nezigidi ezingu-3-4 zeminyaka ngemva kokwakhiwa kwesimiso sonozungezilanga.

Incazelo enengqondo kakhulu yokuhlukaniswa kwala maqoqo ukwakheka kwe-Jupiter, okwadala igebe kudiski ye-protoplanetary futhi kwavimbela ukushintshana kwendaba phakathi kwawo. Ngakho, inkaba ye-Jupiter yakheka ngaphambi kwesikhathi kakhulu kunokuba i- nebula yesimiso sonozungezilanga ihlakazeke. Ukuhlaziywa kwabonisa ukuthi lokhu kwenzeka nje eminyakeni eyisigidi ngemva kokwakhiwa koHlelo.

Ososayensi baphinde bathola ukuthi ngaphezu kweminyaka eyisigidi, umnyombo weJupiter wathola isisindo esilingana nezixuku ezicishe zibe amashumi amabili zomhlaba, kwathi eminyakeni eyizigidi ezi-3-4 ezalandela, isisindo somhlaba senyuke safinyelela kumhlaba ongamashumi amahlanu. Imibono yangaphambilini mayelana neziqhwaga zegesi zithi zakha cishe izikhathi eziyi-10 kuya kwezingu-20 ubukhulu boMhlaba bese ziqoqa amagesi eziwazungezile. Isiphetho siwukuthi amaplanethi anjalo kufanele akhiwe ngaphambi kokunyamalala kwe-nebula, eyayeka ukuba khona eminyakeni eyizigidi ezingu-1-10 ngemva kokubunjwa kwesimiso sonozungezilanga.
