Habitable Hotspots on Mars? Volcano Vents May Be Signs

This volcanic cone in the Nili Patera caldera on Mars has hydrothermal mineral deposits on the southern flanks and nearby terrains, hinting that it may be the most recent habitable hotspot on Mars. Two of the largest deposits are marked by arrows, and the entire field of light-toned material on the left of the cone is hydrothermal deposits.

Five Volcanic Episodes On Mars Identified by Scientists

Martian Volcanoes May Not be Extinct


The three Tharsis volcanoes (bottom, right) straddle the region dominated by Olympus Mons (top left). Scientists think the volcanoes may not be extinct, but rather dormant and waiting for a hot plume of magma to travel beneath them.
