Whakarāpopototia te tuhinga:  (CNN) I puta mai ko Hupita he nui ake i te pounamu nui o te hau e huri ana i etahi rau miriona maero i tawhiti atu i te punaha o te ra. Ko tā tātou, ko ngā tangata whenua, he whakawhetai ki te aorangi nui mō tō tātou noho. E rua ngā kaipūtaiao e whakaaro ana ko te pūnaha ā-roto o te rā i noho i mua ki te tini o ngā "super-Earths" - ngā aorangi i nui ake i tō tātou, engari he iti ake i a Neptune. Heoi anō, i whakamutua e Hupita aua kainoho o mua o nga ara o roto, i takahia e ia ki roto, a, ka horoia atu ki te ra, e ai ki tētahi pepa i whakaputaina i tēnei wiki i roto i te Proceedings of the National Academy of Sciences. Ko te haerenga nui o Hupita ki te rā, me te hokinga mai, i whakatakoto ai i ngā turanga mō te hanganga o te Ao me ētahi atu aorangi iti e tata ana - a Mercury, a Venus me Mars. "Ko ta maatau mahi e kii ana ko te nekehanga o Jupiter ki roto-ki waho ka taea te whakangaro i te whakatupuranga tuatahi o nga aorangi me te whakarite i te waahi mo te hanganga o nga aorangi whenua-kore-nui kei a tatou i tenei ra", e kii ana a Konstantin Batygin o Caltech, tetahi o nga kaituhi o te pepa. E whakamātau ana te ariā ki te whakamārama he aha te take he rerekē te āhua o to tatou pūnaha rā i roto i to tatou rohe ā-rangi. He tino rerekē te āhua o te nuinga o ētahi atu pūnaha he aorangi e huri ana i tētahi whetū e rite ana ki tō tātou rā. I te nuinga o te wā, kotahi tonu te aorangi nui ake i te Ao kei roto i tētahi porohita tata atu i a Mercury. Engari kāore he maha o rātau taonga i tawhiti atu. Tērā pea nā te whakangaromanga o Hupita i te tīmatanga o te hītori o te pūnaha rā. "Kāore he take hei whakaaro kāore i puta i konei te aratau nui o te hanganga aorangi puta noa i te aorangi", e ai ki a Batygin. "Tērā pea kua whakarerekētia e ngā huringa o muri ake nei tōna āhua taketake". Ko ia rāua ko tana hoa kaituhi - ko Gregory Laughlin o te Whare Wānanga o California, Santa Cruz - e hanga ana i runga i tētahi āhuatanga o te nekeneke o Hupita i tukuna i mua e ētahi atu pūtaiao. E mōhiotia ana ko te āhuatanga o te Grand Tack, e whakaahua ana i a Hupita e kukume ana ki te rā i te...
Kairangahau: He nekehanga nui a Jupiter i arahi ki te whakangaromanga o nga "super-Earths" Ko tā rātou, ko te haerenga whakamataku o te ao i whakatakoto ai ngā turanga mō te Ao.
