Fossilized rivers suggest warm, wet ancient Mars

Extensive systems of fossilised riverbeds have been discovered on an ancient region of the Martian surface, supporting the idea that the now cold and dry Red Planet had a warm and wet climate about 4 billion years ago, according ...

Gully patterns document Martian climate cycles
