Ancient Eruption May Change Our Understanding of Modern Volcanoes

by Mara Johnson-Groh 5 February 202112 April 2022

Bubbles trapped in magma from a 1,000-year-old event reveal how scoria cones might erupt and what impact they may have on the landscape and atmosphere.

An Asteroid “Double Disaster” Struck Germany in the Miocene

by Katherine Kornei 27 January 202126 January 2023

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.

Moon May Hold Billions of Tons of Subterranean Ice at Its Poles

by J. Pinson 20 November 202028 January 2022

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.

Who Wants to Count All the Craters on Mars? Not Me!

by P. Fox 21 July 202028 January 2022

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.

Water Ice Lurks in Young—but Not Too Young—Lunar Craters

by Katherine Kornei 15 June 202028 January 2022

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.
