Scientists have uncovered a massive underground magma system on Mars, challenging our assumptions about planetary geology. Using seismic data from the InSight mission, researchers detected a deep boundary rich in iron and magnesium — evidence of a vast, interconnected magmatic network that formed without plate tectonics. This process, called transcrustal magmatism, suggests Mars may have built its crust through complex internal dynamics, similar to Earth’s volcanic arcs. The discovery reshapes our view of Martian history and hints that habitable conditions could emerge on other rocky worlds…
