The Gaia mission’s asteroid survey will help dig deeper into the solar system’s rocky history.
A new method, nano-FTIR, is used to examine microstructures and processes on grains, displaying its benefit for examining asteroid returned samples through a meteorite.
Greenland’s Hiawatha impact structure, more than 30 kilometers in diameter, is much older than previously thought, new results suggest.
When an asteroid struck South Africa during the Precambrian, earthquakes rocked the region for millennia as Earth’s crust reequilibrated, new research reveals.
Spectral data and modeling suggest that volatile-rich main-belt asteroids initially formed at much greater distances from the Sun (>10 AU).
By using data from two lightning-spotting satellites, researchers measure explosions of thousands of small meteors and create a database that could help the planetary defense community.
Spectral data suggest that Kamo‘oalewa, a near-Earth asteroid, has a composition similar to lunar rocks.
Researchers dissolve chunks of the ancient seafloor to trace Earth’s impact history and find that colossal clashes between asteroids don’t often trigger an uptick in meteorite strikes.
Large-scale lava experiments are helping scientists imagine how metallic lava would flow across and shape a landscape, either on Earth or on a distant asteroid.
By analyzing sediments jostled by ground shaking, researchers have shown that two impact craters near Stuttgart were created by independent asteroid impacts rather than a binary asteroid strike.
