Mars may have once been filled with seas of magma that made the Red Planet habitable
Data from NASA's InSight lander suggests that Mars may have once contained deep oceans of magma within its crust, indicated by seismic measurements revealing a boundary 15 miles deep. This discovery challenges existing theories about Mars's early development and its potential for habitability.
Why it matters
This finding could fundamentally change our understanding of planetary formation and the conditions required for life, suggesting that habitability might be possible on more planets than previously thought, even those without Earth-like plate tectonics.
