Continue the search for micrometeorites and mysterious particles from space. Take a closer look at the investigation and ...

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 ...

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 ...

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 ...

Very old samples of small meteorites show that they could have reacted with carbon dioxide on their journey to Earth, researchers report. Previous work suggested the meteorites ran into oxygen, ...

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 ...

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 ...

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

Every year, roughly 10 particles of space dust land on each square meter of Earth’s surface. “That means that they are everywhere. They are on the streets. They are in your home. You may even have ...
