Scientists at the U.S. space agency NASA say they have found evidence of an ancient lake on Mars that could have supported microbial life.
The "Curiosity" rover found evidence of the lake inside Gale Crater where the space craft landed in August 2012.
Scientists say the lake likely covered an area of 50 kilometers.
Scientists say samples gathered by "Curiosity" show the lake existed for at least tens of thousands of years.
Scientists say the lake in Gale Crater could have supported a simple class of rock-eating microbes, which on Earth are commonly found in caves and hydrothermal vents on the ocean floor.
