溫奇科姆隕石支持了地球水理論

對於今天的地球來說,有這麼多的東西--70%的表面被海洋覆蓋--表明一定有後來的補充。

而它在墜落後不到12小時就被回收的事實,意味着它吸收了很少的地球上的水,或者說是任何污染物。

"這意味着當我們測量它的時候,我們知道我們所看到的成分可以一直追溯到46億年前太陽系開始時的成分。

然後只花了20萬到30萬年就到達了地球,通過高速空間粒子或宇宙射線的不斷照射,在隕石材料中產生的特定原子的數量,如氖,顯示了這一點。

"聯合第一作者、格拉斯哥大學的盧克-戴利博士說:"研究人員將在未來幾年內繼續研究這個標本,揭開我們太陽系起源的更多秘密。


For the Earth to have so much today - 70% of its surface is covered by ocean - suggests there must have been a later addition.

And the fact it was recovered less than 12 hours after crashing means it had absorbed very little earthly water, or indeed any contaminants.

"This means when we measure it, we know the composition we're looking at takes us all the way back to the composition at the beginning of the Solar System, 4.6 billion years ago.

It then took only 200,000 to 300,000 years to arrive on Earth, the number of particular atoms, such as neon, created in the meteorite material through the constant irradiation from high-speed space particles, or cosmic rays, reveals.

"Researchers will continue to work on this specimen for years to come, unlocking more secrets into the origins of our Solar System," co-first author Dr Luke Daly, from the University of Glasgow, said.
