Mars' Southern Interior Found Far Hotter Than Northern Half, Study Shows
A new study published in Nature reveals that the interior beneath Mars' southern hemisphere is roughly 400 to 750 degrees Fahrenheit hotter than the interior beneath its northern hemisphere. Researchers led by University of Arizona scientist Alexander Berne used gravity data to uncover this asymmetry, which contrasts with the long-held assumption that planetary interiors are generally uniform in temperature.

This thermal imbalance could reshape scientists' understanding of Mars' early magnetic field, geological evolution, and the conditions that once allowed liquid water and possibly life to exist. The findings may also guide the design of future missions aimed at probing the planet's interior structure and history.
- Mars' southern interior is 400-750°F hotter than its northern interior, per new gravity data analysis.
- The asymmetry challenges assumptions that planetary interiors are spherically uniform.
- The discovery could inform theories about Mars' ancient magnetic field, water history, and future exploration missions.
