The New Horizons spacecraft recorded images of craters that imply an unexpected dearth of small objects in the Kuiper Belt.
Telescopes around the world detected an impact event on the lunar surface just before totality on Monday. Amateur and professional astronomers are starting to coordinate data.
The impact crater is a dry lake bed that contains evidence of ancient water flows and perhaps signs of ancient microbial life.
Ice-penetrating radar revealed a 31-kilometer impact crater—one of the world’s largest—in northwestern Greenland that might have been formed fewer than 20,000 years ago.
Mountains ringing the center of Earth’s most famous impact crater consist of porous rocks. Computer models of the impact can now predict those rocks’ microstructure.
Scientists are using satellite data to study large impact basins on the surface of the Moon that contain magnetic anomalies.
Layered-ejecta craters on Mars that are associated with impacts into rock mixed with volatiles have been formed throughout the planet’s history indicating the long-term preservation of subsurface ice.
Curiosity’s two-step heating experiment of mudstone at Gale crater reveals minerals that formed in the presence of water less than 3 billion years ago.
Directional differences in craters’ optical properties suggest that the solar wind, not tiny meteorites, is the main driver of space weathering on the Moon.
A three-dimensional model of material transport suggests that impact cratering can mix lunar soils across distances of more than 100 kilometers.
