It's the first time that scientists have ever discovered a stable body of liquid on the planet.
Life on Mars has suddenly become more of a probability than it ever has been before, after scientists have located stable 'liquid water' on the planet.
The lake is believed to lay underneath the surface of Mars's southern pole and stretches approximately 20km across.
There have been previous signs of liquid and water activity on Martian slopes, but never before a 'stable body' - which strengthens the notion of alien life inhabiting the planet.
Scientist Dr Orosei admits: "It’s tempting to think that this is the first candidate place where life could persist on Mars.”
"This kind of environment is not exactly your ideal vacation, or a place where fish would swim, but there are terrestrial organisms that can survive and thrive, in fact, in similar environments. There are microorganisms on Earth that are capable of surviving even in ice.”
With the surface of Mars even colder than it is in the Antarctic and Greenland, the water is likely to be a 'briny sludge'. Salt found in the brine is expected to be the core reason that liquid is managing to exist on the planet, as it helps melt icy waters - similar to the way a road gritter removes snow from tarmac.
Scientists will continue to work at discovering more water in order to figure out whether the newfound lake is a one-off, or in fact one in a network of resevoirs.
