Scientists find Mars' southern interior is 200-400°C hotter than its northern half

Scientists discovered Mars' southern interior is much hotter than its northern half.

This temperature difference makes the southern mantle noticeably softer than the north.

Tidal tomography revealed this thermal anomaly beneath the planet's crustal dichotomy.

The findings suggest pockets of mantle beneath the south could still hold trapped magma.

This research offers a direct look into the planet's deep internal structure.
