Scientists discover the first geological evidence of a water system on Mars

Scientists have discovered the first geological evidence of a system of interconnected ancient lakes below the surface of Mars, with the possibility of containing 5 lakes on minerals necessary for life.

In a new study based on Mars Express data, scientists discovered that Mars initially attracted a water system below the surface of the planet.

"The old Mars was an aquatic world, but when its climate changed, the waters dropped below the surface to form aquifers and groundwater," said Francesco Salis, one of the authors of l & # 39; study. On Mars ".

"These lakes have existed for about 3.5 billion years," said Gabriel Gabriel O. Reilly, co-author of the study. "The lakes beneath the surface of the Red Planet could be related to the ocean, which would have existed 4 billion years ago.

Scientists examined 24 deep holes in the northern hemisphere of Mars, located 4,000 meters below the level of the Martian Sea, where they found plaques containing properties that can only be formed by water. water, such as valleys and channels from the walls of the nozzles, It is believed that the dark delta is formed from high and low water levels.
