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 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 ...
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 ...
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, ...
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 ...
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 ...
A selection of fossilized micrometeorites recovered from Cretaceous chalk. These particles were initially composed of Fe-Ni metal but during atmospheric entry they oxidized to form Fe-oxide minerals.
Late last month GOES-13, a weather satellite that helps the U.S. government forecast hurricanes, got smacked by a piece of supersonic space dust. A little micrometeorite, a small-but-incredibly-fast ...
ABOUT 4.6bn years ago, a spinning disc of gas and dust began to coalesce into balls of matter. The largest sphere, at the disc’s centre, collapsed under its own gravity to form the sun. Other clumps ...
