Watch the past 1 billion years of major lunar asteroid strikes in video animation.

The researchers at Southwest Research Institute gave 1.3 billion years' worth of lunar impact data to animators at System Sounds, who compressed that history into two roughly one-minute movies.

The animation above illustrates 111 of the moon's larger impact craters as sound and color, and in the order that they occurred. Smaller craters are represented by higher-pitched and quieter sounds, while the biggest are louder and lower-pitched.
