Liquid water in Mars: New hope of finding life after NASA's Insights Lander evidence
Liquid water exists deep underground rocks. Finding is crucial to understand the cycle of water and the evolution of Martian climate.
New seismic data from NASA's Insights Lander has discovered that a huge reservoir of liquid water may reside deep under the surface of Mars. Previous studies have established the presence of frozen water at Martian poles and the evidence that water vapour existed in its atmosphere. But this is the first time that liquid water has been found on the planet.
Prof Michael Manga, from the University of California, Berkeley told the BBC that water was "the most important molecule in shaping the evolution of a planet". This finding, he said, answers a big question of "where did all the Martian water go?".

Studies have found evidence of water channels and ripples which prove that rivers and lakes did exist on Mars in ancient times. But the planet has been a desert for three billion years as it lost all its water to sun after losing its atmosphere, a protective blanket to life or molecules on surface.
Prof Manga added that much of Earth's water exist underground and there was always a possibility that it could be similar in Mars, called the Earth's twin.
As life cannot exist without water, the finding indicates the possibility of discovering habitable environments deep underground.
