meteorite

I close the meteorite room and try the door across thecorridor..我关上陨石房间的门，又打开了走廊对面的门。

If the contamination were terrestrial, one could expect equal amounts of the molecules (or less) to be present in the meteorite samples, certainly not more..如果污染是来自地面的，在陨石样品中有可能会发现等量（或者较少）的分子，但肯定不会多。

The group, based at Imperial College London, found some of the base building blocks for life, nucleobases, in dust from the Murchison meteorite which fell to Earth in 1969..研究小组由伦敦帝国学院创建，他们在1969年坠入地球的默奇森陨石尘埃中发现了碱基，这是构建生命的基本成分。
