Warm Anomaly Discovered in Mars' Southern Mantle Using Tidal Tomography

Scientists have revealed a massive heat anomaly in the mantle beneath Mars' southern hemisphere, indicating it is 200 to 400 degrees Celsius warmer than other regions. This discovery, published in Nature and made possible by a technique called tidal tomography developed by Brown University researchers, sheds new light on the Red Planet's evolution over the past 4 billion years.
