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 ...
A research project at the Field Museum's Robert A. Pritzker Center for Meteoritics and Polar Studies focuses on identifying micrometeorites from Antarctic sand, which are regarded as "cosmic ...
MINNEAPOLIS - On a hot day, you'll find Scott Peterson on a black rooftop with some basic tools: a hand broom, dustpan, magnet and a ziplock bag looking for Stardust, otherwise known as ...
The book "In Search of Stardust", made up almost entirely of images, provides a brief overview of how scientists can identify micrometeoroids in populated areas. Completing this task requires ...
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.
About 2.4 billion years ago on Earth, something known as the Great Oxygenation Event occurred when Earth's lower atmosphere began to become rich in O2 as oxygen sinks such as dissolved iron and ...
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 ...
A cadre of iron-rich extraterrestrial particles picked up faint whiffs of our planet's atmosphere when they fell to Earth millions of years ago. This article is republished from Eos, read the original ...
NASA’s James Webb Space Telescope has been pummeled by micrometeorites ever since its debut. And while the scientists who developed the ten-billion-dollar observatory were well aware of this reality, ...
It is difficult to imagine that Earth grew from many small bits of dust and debris that were formed long ago in stars. Although most of the solar system debris has settled, meteorites do still enter ...
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 ...
