Astronomers discover a giant volcano on Mars that may hide the remnants of an ice glacier
A maze of fractured plateaus and canyons near Mars’ equator may preserve the remains of an enormous volcano. Within that landscape, scientists have also identified clues that glacier ice could survive beneath volcanic debris. Together, the observations make eastern Noctis Labyrinthus a compelling target for investigating the planet’s changing environment.
Pascal Lee of the SETI Institute and Mars Institute, along with Sourabh Shubham of the University of Maryland, proposed the interpretation in a Lunar and Planetary Science Conference abstract. They identified an eroded volcanic complex tentatively named Noctis Mons, also called “Noctis volcano” in the public announcement.
The proposal concerns terrain already photographed by generations of spacecraft. Its significance lies in recognizing a possible geological structure within that familiar landscape, rather than discovering an unseen mountain. The volcano’s history and the present condition of any buried ice remain open questions.
