41 micrometeorites in less than 2 minutes | The Kid Should See This


“The solar system is a dusty place,” explains Project Stardustfounder Jon Larsen in the caption of one of his videos. “Every day approximately 100 tons of cosmic dust fall down on Earth, mainly as 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.”

This 2015 video, 41 micrometeorites in less than 2 minutes, shares scanning electron microscope images of some of the 0.2-0.5 mm space spherules and prolate spheroid-like particles that Larsen found in Norway.

Larsen was the first to search for, find, and present the discovery of micrometeorites in urban settings, specifically “from accumulated sediments in the gutters of roofs.” He is the author of In Search of Stardust and On the Trail of Stardust: The Guide to Finding Micrometeorites.
