An ancient impact splashed evidence of the Moon’s early mantle makeup onto its surface. Now researchers are piecing together models, maps, and samples to bring these mysteries to light.
By modeling over 4 billion years of the Moon’s impact history, scientists estimate that the lunar poles may harbor billions of metric tons of subsurface ice.
Using climate and habitat modeling, researchers show that solar dimming caused by an asteroid impact would have plunged the world into an “impact winter” and decimated dinosaur habitats.
Humans found hundreds of thousands of craters on Mars greater than 1 kilometer in diameter, but now computers automate the process delivering crater counts as well as geologically meaningful ages.
Using topographic data, researchers have estimated the ages of water ice–containing craters near the Moon’s poles and ruled out volcanism as being a primary route for water delivery.
New analysis of Hubble Space Telescope images suggests that Fomalhaut b, once believed to be an extrasolar planet, is, in fact, a cloud of dust that likely formed from the collision of enormous asteroids.
Research suggests that the spherical structures, smaller than grains of sand, may be microtektites, but additional investigations are needed to verify their identity.
Great Britain’s largest impact crater likely lies in the Scottish Highlands. Scientists dispute whether it’s to the west or the east.
The newly renovated fossil hall at the Smithsonian’s National Museum of Natural History features spectacular fossils and includes a theme of human impact on life on Earth.
A new study explores the origins of massive, multiringed lunar craters.
