Water on Mars: 'RAGING rivers' discovered on Red Planet leave scientists STUMPED express.co.uk

WATER once covered the surface of Mars in the form of huge, raging rivers, a new study of the Red Planet has claimed, leaving scientists scratching their heads. In February, the European Space Agency tweeted a photo taken from their Mars Express probe which revealed a system of trenches, valleys and dried out riverbeds. The discovery suggested the martian planet may have once harvested life in conditions that were much warmer and wetter than today. However, a new study published in Science Advance yesterday claims the Red Planet was actually covered in “intense rivers” much wider than those on Earth.
