Researchers from the University of Oxford have identified evidence suggesting Mars contained extensive networks of molten rock flowing beneath its surface, according to findings published in Nature Astronomy. The discovery was made by analyzing seismic data collected by NASA’s Insight Lander, which detected vibrations generated by meteorite impacts and Martian earthquakes. Scientists used this data to examine a puzzling geological feature located approximately 15 miles below Mars’s surface.
The analysis revealed that this subsurface boundary was most likely created by molten rock accumulating in deep underground reservoirs and spreading horizontally for hundreds or potentially thousands of miles. This finding contradicts previous scientific assumptions that Martian volcanoes were supported by isolated magma chambers. Instead, the evidence points to a more intricate and interconnected system of underground magma circulation.
The implications of this discovery extend beyond Mars itself. Such a complex magma system would have generated a chemically diverse crust capable of recycling elements and facilitating the geological processes necessary for developing an atmosphere and surface ocean. Additionally, this underground activity could have served a climate-regulating function, a role previously believed possible only on planets with active plate tectonics.
The findings suggest that rocky planets lacking plate tectonics should not be automatically dismissed as inhospitable. The presence of active subsurface magma systems may provide alternative mechanisms for supporting conditions favorable to life, thereby expanding the range of worlds considered potentially habitable.
