Scientists detect vast hidden magma systems beneath Mars surface

Beneath the familiar rust of Mars, seismic waves have carried a quiet revelation: the planet's interior holds vast, hidden magma systems that speak to a far more turbulent geological past than science had allowed. Researchers analyzing tremor data have found evidence of a melt-depleted lower crust and large-scale vertical movement of molten rock — signs that Mars was once a world of considerable internal fire. This discovery does not merely revise a footnote in planetary science; it reopens fundamental questions about Mars' thermal history, its lost magnetic field, and whether warmth still lin
