Between 200 and 400 degrees Celsius: That is the estimated temperature gap separating Mars’ southern interior from its northern interior. The result does not mean the southern surface is uniformly ...

New research has uncovered a major mystery deep inside Mars, where differences between the planet’s northern and southern regions reveal an unexpected internal structure. The findings, published in ...

New research into the interior of Mars further emphasizes that the Red Planet is a world of two very different halves.

Despite its dry, dusty surface and thinner atmosphere, Mars may have more in common with Earth than scientists previously thought. In a new study, researchers at the University of Rochester—including ...

Brown researchers found that the southern half of Mars’s mantle contains an anomaly 200 to 400 degrees Celsius warmer than the northern half.

Scientists have found that Mars is not the geologically uniform ball of rock it might appear from orbit. New analysis of nearly two decades of spacecraft tracking data shows that the mantle beneath ...
