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.
Chemical and mineralogical evidence of fluid flow—potentially conducive to microscopic life—was revealed in rock cores extracted from the crater’s “peak ring.”
Rumbling volcanoes act like giant musical instruments that researchers can study to better monitor eruptions.
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.
Three billion years ago, on Mars, the shores of an ocean may have been flooded by a mega-tsunami. Now the crater left by the bolide impact that probably triggered the tsunami has been identified.
Great Britain’s largest impact crater likely lies in the Scottish Highlands. Scientists dispute whether it’s to the west or the east.
A new study explores the origins of massive, multiringed lunar craters.
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.
