而这一个小时的雹灾却造成了成千上万次的撞击，产生全球性的火灾并且在“灭绝的边界”(指陨石或陨石坑)沉积了很多“纳米钻石”，造成了当时很多物种的灭绝。
It would have caused thousands of impacts, generating global fires and depositing nanodiamonds at the 'extinction boundary' marking the point in time when many species died out.
巨大的撞击创造了显微镜下才能看到的“纳米钻石”，而且仅在陨石或者陨石坑中发现了这种“纳米钻石”；这些陨石或陨石坑也被发现可以追溯到那次灾难性的撞击。
Microscopic 'nanodiamonds' created in massive shocks and only found in meteorites or impact craters have also been discovered dating back to the disaster.
乍看上去，斯特恩斯就是一颗5公里宽的钻石；但当罗塞塔与它擦身而过，撞击坑和更多扩展的形状变得更为清晰了。
At first glance, Steins looked like a 5-kilometer wide diamond, but as Rosetta shot by, craters and a more extended shape become evident.
