In a major breakthrough, a European spacecraft has help scientists discover a huge salty water lake on Mars and the lake appears to be buried deep inside the surface of the red planet – raising hopes to find life on the planet.

Water is usually, a sign of life because it is essential for any life to exist and survive – at least that’s what we humans and our astrobiology principles suggest. Since ages, humans have looked upon the skies and have wondered whether anybody else out there in the infinite universe, other than us regular earthlings. The never-ending quest to find extra-terrestrial life has led us to Mars, desperately looking for life or signs of life like water, on the deserted arid and hostile terrains of the red planet.

In a massive breakthrough, a European spacecraft Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) collected some data regarding the landscapes of Mars, using which, a team of Italian researchers discovered liquid water on the red planet. The liquid water is found in form of a huge salty water lake that is buried 20 kilometres beneath the layer of Martian icy surface. Italian space researcher Enrico Flamini confidently claims saying, “Water is there. We have no more doubt”, and if they are right, this is the first largest water body discovered on Mars.

The discovery is testified by the fact that the now cold, barren and lifeless-like Martian surface was once warm and home to plenty of liquid water and lakes at least 3.6 billion years ago. About the possibility of life in the large salty lake on Mars – considering the current temperature and the amount of salt content in the lake, earth-like life is very unlikely to exist. But, the discovery of water (even if it is unbearably salty) surely increases the possibility of living on Mars. Either way, the new finding opens up billions of new possibilities. In the end, we never know what happens next.
