# Thermal Anomaly Found Beneath Mars's Crustal Split via Tidal Tomography

Researchers used tidal tomography to identify a thermal anomaly deep beneath Mars's crustal dichotomy, the boundary between its northern lowlands and southern highlands. The finding provides new clues about the planet's internal structure, heat flow, and how its surface features formed. This helps refine models of Mars's geological and thermal evolution.
