Ice Planet Survey: Evidence Of Lost Mountains From Antarctica’s Past

by Keith CowingJune 16, 2025June 13, 2025

A new study led by University of Wisconsin-Oshkosh geologist Timothy Paulsen and University of Colorado Boulder thermochronologist Jeff Benowitz advances the understanding of the geologic history of Transantarctic Mountains bedrock, […]

Gravity map of Mars. The red circles show prominent volcanoes on Mars and the black circles show impact crates with a diameter larger than a few 100 km. A gravity high signal is located in the volcanic Tharsis Region (the red area in the centre right of the image), which is surrounded by a ring of negative gravity anomaly (shown in blue).
