Mars' Southern Half Is Weirdly Warm Underground. The 'Thermal Anomaly' Might Explain Why the Planet's Hemispheres Look So Different
Researchers used decades of spacecraft gravity data to map a partially molten southern interior and challenge assumptions about Mars's symmetry.

Tropical data reveal that the southern Mars scarf is about 200 to 400 degrees Celsius hotter than the north, which re-explains its surface differences and geological and aquatic history.
Mars' Southern Half Is Weirdly Warm Underground. The 'Thermal Anomaly' Might Explain Why the Planet's Hemispheres Look So Different
Researchers used a novel technique to figure out what's going on inside the Red Planet. The work suggests that the interior of the southern hemisphere is hundreds of degrees hotter than that of the northern hemisphere and partially molten
Mars's Interior is 400°C Hotter Under Southern Hemisphere
The planet Mars is a cold and dry world completely devoid of life, but billions of years ago things were much different. This is when Mars had a much warmer interior than it does today, resulting in active volcanism that replenished its atmosphere, a magnetic field that protected the planet from harmful solar and cosmic radiation, and a surface of flowing liquid water. But due to Mars’s small size, the interior cooled far faster than Earth’s has…
Mars is a cold world on the outside, but is it also so on the inside? New research into the Red Planet's subsurface has revealed major anomalies. It turns out that Mars' southern hemisphere is up to 400 degrees warmer than its northern one. The discovery was made by a team of researchers led by Alexander Berne.
New research into the interior of Mars has revealed that the red planet is composed of two distinct hemispheres. Scientists have recently discovered a massive thermal anomaly deep beneath the Martian surface, adding further questions to the mystery of the extreme asymmetry between the planet's northern and southern hemispheres.
From 16 years of radio measurements of three orbiters, planetary researchers conclude that the mantle under the southern highlands is about 200 to 400 degrees Celsius warmer than in the north and reacts significantly softer. The cause of this deep asymmetry is still open. Pasadena (U.S.A.). Mars indicates [...] Der Beitrag 200 – 400 degrees Celsius: Thermal anomaly discovered under the Mars South Pole first appeared on scanxx
