Mars Reveals Deep Heat Divide, Southern Interior Potentially Hundreds of Degrees Hotter

Scientists have identified a massive heat anomaly deep within Mars, revealing a hidden temperature divide between the planet’s northern and southern interiors. Measurements indicate that the southern interior could be hundreds of degrees hotter than the north and may be partially molten. This discovery was made through analysis of seismic data and thermal imaging from orbiting spacecraft. The presence of such a temperature contrast could explain several long‑standing Martian mysteries, including the planet’s unusual magnetic field, its seismic behavior, and clues to the history of water on Mars. The finding provides a new framework for interpreting Mars’ interior dynamics and may influence the design of future exploration missions.
