There are many mysteries hidden on Mars
Recent research on the gravity field of Mars has revealed many mysteries. The research has revealed huge, hidden structures beneath the surface of Mars, where an ancient ocean once flowed. According to Science Alert, scientists made this remarkable discovery by combining data from multiple space missions and advanced modeling. The findings showed that active processes in the Martian mantle could have fueled the growth of Olympus Mons, the solar system’s largest volcano.
Mars is full of many mysteries
Bart Root from Delft University of Technology (TU Delft) presented these fascinating findings at the Europanet Science Congress (EPSC) in Berlin, shedding new light on the mysterious interior of the red planet. “These dense structures could be volcanic in origin or could be compressed material from ancient impacts. We have identified about 20 features of different shapes scattered across the north polar region, including one that resembles the shape of a dog,” said Dr Root.
Dr Root and his research team took a new approach to examining the internal structure of Mars, examining the planet’s gravity field, and probing its internal mass. The density map showed that the north polar regions are denser by 300-400 kg/m³. The study also revealed new information about the solar system’s largest volcano, Olympus Mons. Dr Root and his team discovered a huge, light structure about 1,750 kilometres wide, located 1,100 kilometres below the surface, which is causing the Tharsis region to move upward.
Volcanoes may have been active on Mars at some point
“The NASA InSight mission has provided important new data about the hard outer layer of Mars. This suggests that Mars may still be experiencing active activity in its interior, which could influence and even create new volcanic features on the surface,” Dr. Root said. Although there are currently no active volcanoes on Mars, this new discovery suggests that Mars may have become volcanically active more recently than previously thought.
