This strange plume could help to explain not just Mars' quicker rotation but also how the planet holds on to geologic heat far longer than expected — forcing scientists to rethink how small, rocky worlds cool and die. "The Martian surface is so old and shows all these complex but largely not well understood process, which I think we can start to unravel by combining interior with surface,", an assistant professor of planetary exploration at the Delft University of Technology in the Netherlands and first author of the study, told Live Science in an email."Understanding Mars will help in understanding ourEnormous 'mega-blob' under Hawaii is solid rock and iron, not gooey — and it may fuel a hotspotplate tectonics , the shifting crustal plates that drive much of our planet's volcanic activity. Instead, the lava from Mars' ancient active volcanoes just sits there, piling up and building far bigger structures over time. This resulted in the formation of thesent the InSight lander to the Red Planet to better understand the planet's interior, which, in turn, could help reveal more about its volcanoes. For years, the lander studied Mars' interior, giving scientists a direct estimate of the crust's thickness. Using data from InSight, Root and the team ran computer simulations to test what kinds of structures could explain why the volcanic region has dominated one side of Mars. Those models pointed to a plume of unusually light material — called a"negative mass anomaly," or something less dense than the rock that surrounds it — in the mantle beneath the Tharsis region. According to the researchers, this anomaly may explain how the Tharsis region became so large and full of volcanoes.Get the world’s most fascinating discoveries delivered straight to your inbox.Receive email from us on behalf of our trusted partners or sponsors "The negative or light mass anomaly will move upwards and hit the lithosphere of Mars, introducing melt pockets that have the potential to penetrate the crust and erupt as volcanoes," Root said. .
