Long imagined as a cold, geologically dormant world, Mars is now revealing a far more turbulent interior than anyone anticipated.
Scientists have identified a pronounced heat anomaly buried deep within the planet, concentrated beneath its southern hemisphere.
According to the analysis, this southern interior may run hundreds of degrees hotter than its northern counterpart.
Remarkably, a portion of the deep material appears to be partially molten, blurring the line between solid rock and viscous liquid.
Such a stark thermal imbalance overturns the long-held picture of a planet cooling quietly and uniformly from within.
Instead, it points to a complex internal engine still shaping the Martian body in ways researchers are only beginning to grasp.
The discovery carries profound implications for how Mars formed, differentiated, and lost much of its early activity.
By peering into this hidden warmth, scientists hope to reconstruct the planet's deep history with unprecedented clarity.
Mars, it turns out, guards a molten secret that could rewrite its geological story.
