Probing the History of New Zealand's Orakei Maar

by P. C. Augustinus 20 September 201623 September 2022

A team of scientists drilled into the bed within a northern New Zealand explosion crater lake to gain insights into volcanic hazards and past climates.

Tsunamis Splashed Ancient Mars

Shannon Hall by S. Hall 19 May 201628 January 2022

Massive meteorites likely slammed into a Martian ocean billions of years ago, unleashing tsunami waves up to 120 meters tall, a close study of a region of the Red Planet's terrain has found.

This relatively recent impact crater photographed last year spans a little more than a kilometer in the Sirenum Fossae region of Mars.

Can Meteorite Impacts Disturb a Planet's Magnetic Field?

Kate Wheeling, freelance science writer by Kate Wheeling 8 February 201628 January 2022

Such disturbances probably do not occur on our own planet, but evidence for them might still exist elsewhere in the solar system.

Subsurface Craters Expose the Moon's Dramatic Past

by L. Strelich 22 October 201528 October 2021

Scientists use the gravity signature of the lunar surface to trace the history of impact cratering and its role in the Moon's evolution.

Craters Could Make Great Impacts on Mars Exploration

by G. H. Shaw 23 July 201528 January 2022

Future robotic missions to Mars hoping to peer beneath its surface in search of signs of life should target recent impact craters, where falling meteorites have done the drilling for them.
