The possibility of Life on Mars is subject to significant interest to astronomers due to its proximity and similarities to Earth. To date, no proof has been found of past or present life on the Red Planet. However, a discovery made by scientists at the European Space Agency (ESA) yesterday could be the “Holy Grail” scientists have been looking for.
Photos snapped by the team showed signs that liquid water once flowed on the planet's surface.
The incredible satellite images revealed what looks like an ancient and intricate system of trenches, valleys and dried out riverbeds, suggesting previous life.
Identical systems are seen on Earth, such as the Yarlung Tsangpo river, which runs from western Tibet through China, India and Bangladesh.
In the case of Mars, the ESA said the branching waterways are most likely the result of surface water runoff from powerful rivers and extensive rainfall.
