Mars' southern hemisphere hotter than north, revealing deep thermal anomaly

Scientists have identified a significant thermal anomaly deep within Mars, with the southern hemisphere's mantle being considerably hotter than the northern. This discovery, made using data from three Martian orbiters and a technique called tidal tomography, offers new evidence to explain the long-standing mystery of the Martian dichotomy—the stark difference in elevation and geology between the planet's hemispheres. While the exact cause of this temperature difference remains under investigation, potential explanations include mantle convection or long-term insulation beneath the southern highlands, providing crucial insights into Mars' internal processes and past habitability.
