Quanta Magazine - Season 2021

DESCRIPTION

Every year, roughly 10 particles of space dust land on each square meter of Earth’s surface. Matthew Genge, a planetary scientist at Imperial College London, specializes in these alien dust grains, known as micrometeorites. They float here from space rocks hundreds of millions of miles away, bearing tiny messages about the mysteries of our solar system.
