Mars

NASA’s Curiosity Mars rover used two different cameras to create this selfie in front of Mont Mercou, a rock outcrop that stands 20 feet tall. New analysis by Penn State researchers reveals that much of the craters on Mars today could have once been habitable rivers. Credit: NASA/JPL-Caltech/MSSS. All Rights Reserved.

Mars rover Perseverance helped scientists study layered rocks like these in Jezero Crater on the Martian surface. Scientists initially thought they were sedimentary rocks, but further examination showed them to be igneous rocks – solidified lava. These rocks show evidence of interaction with water, but on a limited basis. They date back nearly 4 billion years, giving scientists a window into what conditions on the early planets were like.
