The brightest area on Ceres, located in the mysterious Occator Crater, has the highest concentration of carbonate minerals ever seen outside Earth, according to a new study from scientists on NASA’s Dawn mission. The results suggest that liquid water may have existed beneath the surface of Ceres in recent geological time.
Volcanoes erupted beneath an ice sheet on Mars billions of years ago, far from any ice sheet on the Red Planet today, new evidence from NASA’s Mars Reconnaissance Orbiter suggests. The research about these volcanoes helps show there was extensive ice on ancient Mars. Such an environment combining heat and moisture could have provided favourable conditions for microbial life.
