Gravity Data Reveals Mars Is Hundreds of Degrees Hotter in the South
August 31, 2026
Researchers have found a major temperature imbalance deep inside Mars, with the planet's southern interior appearing significantly hotter than its northern half and possibly partially molten. The discovery, drawn from decades of gravity measurements, offers a new window into the Red Planet's geologic history, including periods when Mars may have had environments capable of supporting life. Mars has long been known to look very different across its two hemispheres. The southern surface is domina
