"Shorelines are great locations to look for evidence of past life." Today, Mars is a chilly desert of rock and dust — but 4 billion years ago, the planet had rivers, lakes and even oceans with sandy ...

Whether it's rivers cutting through earth, lava melting through rock, or water slicing through ice, channels all twist and bend in a seemingly similar back-and-forth manner. But a new study led by ...

Step aside, Santa Monica. It seems that Mars once had beaches that would give the Californian coast a run for its money.

NASA’s Perseverance rover found pale rocks containing kaolinite on Mars, a mineral that forms in warm, wet conditions.

Rivers could have been responsible too, but the area Zhurong studied lacked the telltale river valleys that would have been left behind after the water evaporated. Read More: NASA's Mars Rover ...

“We tend to think about Mars as just a static snapshot of a planet, but it was evolving,” Cardenas said. “Rivers were flowing, sediment was moving, and land was being built and erode ...
