Scientists Discover Massive Warm Spot in Mars' Mantle Using Tidal Tomography

A study published in the journal Nature, led by researchers from Brown University and the University of Arizona, has revealed a massive heat anomaly in the mantle beneath Mars' southern hemisphere. Utilizing a technique called tidal tomography, which analyzes subtle changes in the gravity field caused by the Sun's tidal forces on Mars, scientists found that this hot spot is 200 to 400 degrees Celsius warmer than the rest of the planet. This discovery sheds new light on the Red Planet's thermal evolution over the past 4 billion years.
