New traces of life found on Mars

Catherine Weitz and her colleagues from the Institute of Planetology (USA) have discovered yet another proof that there could have been life on Mars at some point. This conclusion was made based on the information obtained by interplanetary station NASA Mars Reconnaissance Orbiter. The researchers are talking about two depressions 30-40 km long, located in the region of Noctis Labyrinthus ("the labyrinth of the night").



These depressions contain a type of clay called smectites, which contains a blend of silica with aluminum, iron or magnesium. This is a group of hydrous silicates formed by weathering of mainly alumina-silicates and silicates of igneous and metamorphic rocks on the soil surface. These rocks are formed in the water with neutral acidity. Read More
