Something was wrong with Martin Suttle’s micrometeorites. The Ph.D. student at Imperial College London had collected 76 tiny grains of space dust that had fallen to Earth near the white chalk hills of ...

Every year, thousands of tons of tiny micrometeorites, each smaller than a poppy seed, rain down on our planet, dusting it ...

Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Robyn Williams: The Science Show has also been preoccupied in recent times with the ancient Earth, life ...

Each year, more than 3,000 tons of space dust fails to burn up in our planet’s atmosphere and falls instead to Earth’s surface. These micrometeorites are just a few microns in diameter, but scientists ...

Samples brought back by the Hayabusa2 mission show that the asteroid Ryugu was hit by a barrage of micrometeorites only 1,000 years ago. The evidence? A thin film of sodium, a few nanometers thick, ...

Space is very much the final frontier for humanity, at least as far as our current understanding of the universe takes us. Only a handful of countries and corporations on Earth have the hardware to ...

As I look down into a Petri dish of sand through a binocular microscope, the larger grains become obelisks, with smaller ones forming avenues between them. It’s a microscopic echo of the Chicago ...

More than 100 billion micrometeorites (MMs) fall to Earth each year. Until now, scientists believed that these particles could only be found in the cleanest environments, such as the Antarctic. In ...

Japanese researchers have discovered the first micrometeorites known to land on Earth. No larger than droplets of fog, the spherical, iron-rich particles arrived 240 million years ago, 50 million ...

Micrometeorites are a potential hazard for any space mission, including NASA's Mars Sample Return. The tiny rocks can travel up to 50 miles per second. At these speeds, "even dust could cause damage ...
