Published in Science Advances, the findings challenge the long-held view that Mars is geologically dead. An international research team links the gas detections to possible active volcanism near the planet's largest volcanoes. The discovery implies ongoing geological activity that could sustain subsurface habitats.Why it mattersMars has been considered geologically inactive for billions
