Jupiter ke ea khale ka ho fetisisa!

Hoa etsahala hore polanete ea khale ka ho fetisisa tsamaisong ea lipolanete ke Jupiter. Sena se boleloa ke bo-rasaense ba Lawrence Livermore National Laboratory le Institute of Paleontology Univesithing ea Munster. Ka ho ithuta ka li-isotopes tsa tungsten le molybdenum ka meteorite ea tšepe, ba fihletse qeto ea hore li tsoa lihlopha tse peli tse arohaneng kae-kae pakeng tsa limilione tse limilione tse 3-4 ka mor'a ho thehoa ha letsatsi.

Tlhaloso e utloahalang ka ho fetisisa ea ho arohana ha lihlopha tsena ke ho thehoa ha Jupiter, e leng se ileng sa etsa hore ho be le lekhalo ka har'a disk ea protoplanetary le ho thibela phapanyetsano ea taba pakeng tsa bona. Kahoo, karolo e bohareng ea Jupiter e ile ea bōptjoa pele ho nako pele nebula ea potoloho ea lipolanete e fela. Tlhahlobo e bontšitse hore sena se etsahetse lilemo tse milione feela ka mor'a ho thehoa ha Tsamaiso.

Bo-rasaense ba boetse ba fumane hore lilemo tse fetang milione, mokokotlo oa Jupiter o fumane boima bo lekanang le hoo e ka bang mashome a mabeli a lefats'e, 'me lilemong tse limilione tse 3-4 tse latelang, boima ba polanete bo ile ba eketseha ho ba mashome a mahlano a lefatše. Likhopolo tse fetileng mabapi le linatla tsa khase li re li theha boima ba Lefatše ka makhetlo a 10 ho isa ho a 20 ebe li bokella likhase tse li potolohileng. Qeto ke hore lipolanete tse joalo li tlameha ebe li ile tsa thehoa pele ho nyamela ha nebula, e ileng ea khaotsa ho ba teng lilemo tse limilione tse 1-10 ka mor'a ho thehoa ha letsatsi.
