Planetary Billiards

A recent chemical analysis of a nearby white dwarf star has revealed a recent collision of planets very like the one which formed the Earth's moon. The chemical signature found is very weird for a star, but fits well for a rocky planet. That we can see it at all means the event probably happened less than 50 million years ago.
