They believe that the water found on Mars is in the form of a lake in the southern polar icy area, which is spread over an area of about 20 kilometers and which is present about one kilometer below the icy surface.
Earlier research found possible signs of liquid water on the surface of Mars, but this is the first such evidence that water is present.
NASA's Curiosity Rover discovered the bottom of the lakes that water has been present on the surface of Mars in the past.
However, due to the erratic atmosphere, the climate of Mars is colder than before due to which the water present here has turned into ice.

This new discovery was made possible with the help of Marsis. Marsis is a radar device on Mars Express Orbiter.
Professor Roberto Orocei of the Italian National Institute of Astrophysics, who led the study, said that it "could possibly be a very large lake."
However, Marces could not ascertain the depth of liquid water. But the research team estimates that it can be at least one meter.
Professor Orossei says, "All that is found is water. It is like a lake, not like a molten ice filled between rock and ice."
Importance of this quest for life chances?
Nothing can be said about the possibilities of life from this recent discovery on Mars.
"We have been aware for a long time that there are no favorable conditions for life on the surface of Mars. But now our search has progressed a bit," explains Manish Patel, a doctor associated with the Open University.
The condition of water is extremely important in astrobiology. In this region, besides earth, life is studied.
The new discovery suggests that water exists on Mars, but the conclusion about the possibilities of life cannot be reached.
Dr. Patel says, "We have not come close to the possibility of life. But this discovery shows where and in which direction we have to move on Mars. It is like a map of hidden treasures."
What will happen next?
The discovery of the presence of liquid surface is a good opportunity for researchers who are exploring the possibilities of life on Mars in the past and present.
