该团队研究了在小行星地壳上形成的磁铁矿粒之间的边界和孔隙中的分子。在这些边界和孔隙中,该团队发现了在晶粒边界上留下的水沉淀物,他们在此基础上进行了开创性的研究。主要作者李-怀特博士说,科学家们知道早期太阳系中水很丰富,但是几乎没有任何直接证据表明液体的化学性质或酸度。
这些液体的化学成分和酸度对于氨基酸的早期形成和进化,以及最终的微生物生命的形成和进化至关重要。原子尺度的研究为科学家们提供了第一个证据,证明了磁铁矿框体形成时的富钠和碱性液体。这种流体条件有利于氨基酸的合成,为早在45亿年前的微生物生命形成打开了大门。
研究人员表示,氨基酸是地球上生命的重要组成部分,但关于氨基酸在太阳系中是如何形成的,科学家们还有很多东西要学。研究小组对温度和pH值的了解越多,他们就越能了解分子的合成和进化,以及我们所知道的地球上的生物生命。
塔吉什湖碳质球粒陨石是在2000年从不列颠哥伦比亚省塔吉什湖的一块冰盖中回收的,后来被皇家安大略博物馆收购。研究小组使用的样品从未超过室温或暴露于液态水,从而使科学家能够将测得的流体与母体小行星联系起来。原子探针层析成像技术使科学家能够在比人类头发稀疏一千倍的少量物质上进行发现。
