The aquatic past of Mars continues to fascinate scientists: before becoming the red planet we know today, could the celestial body have been nicknamed the blue planet? A recent study may have found the answer to this mystery in geological formations with unsettling similarities.
While Mars presents itself to us as an arid desert, its aquatic past has intrigued scientists for many years. For good reason, several hypotheses are advanced, but none are unanimous: liquid water present in large quantities under the Martian surface, isolated lakes, empty porous spaces, impressive ice deposits resulting from an ancient explosive phenomenon…
This question is all the more vital as it subtly questions the ability of the celestial body to have one day harbored life. But to what extent could Mars, now known as the “red planet”, have once been nicknamed the “blue planet”?
