Billion-year-old hidden magma system on Mars may have supported life

Scientists have uncovered evidence of a massive magma system beneath Mars' surface, challenging the long-held belief that such complex geological activity requires tectonic plates. NASA's InSight lander data revealed a distinct boundary deep within the Martian crust, suggesting a vast, ancient magma chamber that cooled and crystallized. This discovery hints that the ingredients for life might be more common on Mars than previously thought, prompting a re-evaluation of planetary habitability.
