- Where have scientists found evidence of water?
- Mars - Young gullies on Mars. These valleys, possibly caused by flowing water, are about 3 kilometers (2 miles) wide and line a south-facing wall of a large crater. Researchers suggest these furrows formed between 10,000 and 1 million years ago. Their recent formation is indicated by the lack of surface craters.
