Tiny pieces of space rock called micrometeorites are everywhere on Earth. In Search of Stardust shows you how to find them and keep them safe.
The solar system is a dusty place. Every day approximately 100 metric tons of cosmic dust collides with Earth, mainly in the form of micrometeorites. Most of these mineral particles (iron, nickel, etc.) are smaller than grains of sand, and they are falling down on us all the time and all over the globe. Still, little is known about these exotic extraterrestrials.
