China’s Zhurong Mars rover has discovered evidence that liquid water flowed on the red planet within the past 1.4 million years, suggesting that modern Mars might not be as inhospitably dry as previously assumed. Given that water is the essential ingredient for life on Earth, the new findings have major implications in the ongoing search for aliens on Mars.

More than three billion years ago, Mars was home to gushing rivers and enormous lakes that might have provided the right conditions to support simple forms of life, such as microbes. But the planet has lost most of its atmosphere since that golden age, transforming it into a desiccated husk with a surface exposed to highly damaging radiation.
