A provocative new study of photographs taken from orbit suggests that liquid water flowed on the surface of Mars as recently as several years ago, raising the possibility that the Red Planet could harbor an environment favorable to life.

Evidence is mounting that    the time-weathered red planet was once a warm and water-rich world. And a Mars    awash with water gives rise to that globe possibly being fit for habitation    in its past - and perhaps a distant dwelling for life today.

The European Space Agency(ESA) says it has found concentrations of water vapour and the gas methane in the same places on Mars, which strengthen speculation that the Red Planet could be a haven for microbial life.

Recent analyses of ESAÃ¢ÂÂs Mars Express data reveal that concentrations of water vapour and methane in the atmosphere of Mars significantly overlap. This result provides important new hints to evaluate the hypothesis of present life on the Red Planet.
