Jupiter waa kan ugu da'da weyn!
Waxaa soo baxday in meeraha ugu da'da weyn nidaamka qorraxdu uu yahay Jupiter. Tan waxaa sheegay saynisyahano ka socda Shaybaadhka Qaranka Lawrence Livermore iyo Machadka Paleontology ee Jaamacadda Munster. Markii ay daraaseeyeen isotopes-ka tungsten iyo molybdenum ee meteorites-ka birta, waxay ku soo gebogebeeyeen inay ka yimaadeen laba rucubood oo midba midka kale ka soocay meel u dhaxaysa hal milyan iyo 3-4 milyan oo sano ka dib markii la sameeyay nidaamka qorraxda.
Sharaxaada ugu macquulsan ee kala soocida kooxahan ayaa ah samaynta Jupiter, taas oo abuurtay farqiga u dhexeeya saxanka protoplanetary kana hortagaya isdhaafsiga walxaha dhexdooda. Haddaba, xudunta Jupiter ayaa samaysmay wax aad uga horreeyay nebula hab-dhiska qoraxda. Falanqaynta ayaa muujisay in tani ay dhacday hal milyan oo sano ka dib markii la sameeyay Nidaamka.
Saynis yahanadu waxa kale oo ay ogaadeen in in ka badan hal milyan oo sano, xudunta Jupiter ay heshay cuf u dhigma ku dhawaad labaatan masses Earth, ka dibna in ka badan 3-4 milyan oo sano ee soo socda, tirada meeraha kor u kacay ilaa konton miisaanka Earth. Aragtiyo hore oo ku saabsan gaaska gaaska ayaa sheegaya in ay sameeyaan qiyaastii 10 ilaa 20 jeer xajmiga dhulka ka dibna ku ururaan gaas iyaga ku wareegsan. Gabagabada ayaa ah in meerayaasha noocan oo kale ah ay sameeyeen ka hor inta aan la waayin nebula, kaas oo joojiyay inuu jiro 1-10 milyan sano ka dib samaynta nidaamka qorraxda.
