Ancient Mars may have been covered in ice: study

A new study suggests that Mars' ancient valleys were formed by glaciers rather than rivers, indicating a colder and icier past. Researchers compared these valleys to those on Devon Island, a terrestrial analog. The study proposes that glaciers created meltwater channels on Mars 3.8 billion years ago, potentially offering conditions favorable for ancient life by deflecting solar radiation.
