• The European Space Agency's Mars Express orbiter captured detailed images of the Caralis Chaos region on Mars.
• Lake Eridania, believed to have existed 3.7 billion years ago, was larger than the Caspian Sea and covered an area the size of Egypt.
• The lake's remnants include raised mounds formed by ancient winds, volcanic activity evidence, and impact craters.
• Mars lost its water as its atmosphere eroded due to the absence of a protective magnetic field.
• Scientists are studying these regions to understand Mars' potential to have hosted microbial life.
