Italian scientists have discovered a lake about 21 kilometers in diameter on the southern axis of Mars. He is behind the ice cover.

This is the first time that Marseille discovers a stream of liquid water.Live creatures can exist on the surface of Mars.
The British Guardian quotes the National Institute of Astrophysics, Roberto Orosei: "We found water. The data is completely reliable. "
Today, only the old dry fence limiting the surface of Mars reminds us that there was water on the surface of the planet before millions of years ago. In 2015, NASA researchers said they spotted surface water currents, but last year, US geologists dismounted their NASA colleagues, seeing that they did not see running water and rubbing the pebble
Italian scientists badyzed the data collected by the Mars Express for three years and did not doubt that the radar signals penetrated easily into the ice after being reflected by the surface of the water plane. : "The data must be carefully badyzed.The conclusions are really true."
The scientist of the University of Rome Trevor Elena Pettinelli said that there is no way to fully say if the body of water found is a lake or another form. In the opinion of the scientist, if it is a lake, it should be very similar to Lake Vostok located on the Antarctic ice on Earth.
Scientists can not determine the depth of Lake Marseille. According to radar data, the tank is deep at least 1 to 2 meters
However, they really know that the lake water is very cold. The presumed temperature at this depth is 68 degrees below zero. Although the temperatures are so low, the water may be liquid because of its high pressures and high salinity. It is believed that there is a lot of calcium and magnesium perchlorates in the water found on the entire surface of Mars.
Although conditions in Lake Mary are very severe, scientists believe that it can contain germs adapted to high salinity. "This is not the most enjoyable environment for life.I think it's very difficult to imagine life," said Roberto Orosei.

. Septon, The Guardian, explains life in extreme conditions at Imperial College London, saying that the mere fact that the water is deep does not constitute existence.The surface of the planet is constantly exposed to a radioactive "bombardment" that sterilizes the entire planet, so if there is life on the planet, it is probably underground. "As long as there is energy and food resources, life is possible, "said a scientist.
" Salt helps maintain a fluid state, but poses a challenge to life. If the salt concentration around the cell is higher than in the cell itself, the water is extracted. Life can adapt, synthesize organic molecules and stop the process, but there are limits, "Mark Sephon said. "So some mechanisms that allow Marse to be liquid water are unfavorable to life," he said.
The day scientists can study the water after the fall of Martian ice even more quickly. "Screwing up there and getting the final proof that it's a lake will be a daunting task." According to scientists from Bologna, scientists are exploring other areas of Mars and are looking for signs of other mbades. Groundwater There is no scientist able to overcome a mile and a half of ice, which requires technologies that we do not have today.
