耕耘月球的宇宙档案

当流星体撞击月球表面时，会挖掘出记录着远古超新星爆发的宇宙历史。夏威夷大学的研究人员开发出一种方法，旨在解读这些历史并深入了解宇宙中此类高能事件。

When a meteoroid hits the Moon's surface, it does more than just dig up a little dirt. It actually excavates a little bit of cosmic history that recorded a long-ago supernova explosion. Scientists at the University of Hawaii Institute of Geophysics and Planetology have come up with a way to decode that history and learn something about such energetic events in the Universe.
