Scientists have discovered thousands of miles of ancient riverbeds on Mars, significantly altering our understanding of the planet's past.
These newly found river systems, dating back over three billion years, suggest a much wetter Mars than previously imagined.
High-resolution images from Mars orbiters revealed the extensive network of rivers in the Noachis Terra region.
This discovery challenges previous assumptions about water scarcity in this area and points towards a period of substantial rainfall or snowfall.
