Researchers just discovered evidence to suggest that Mars was once home to oceans and sandy beaches on the red planet, according to data published by the Proceedings of the National Academy of Sciences.

Data from China's Zhurong rover on Mars suggests an ancient ocean and strengthens evidence that the planet was once warm, wet, and habitable.

A new study, based on data from China’s Zhurong rover, gives the ‘clearest evidence yet’ that billions of years ago, Mars had vast oceans, with buried coastlines beneath its now barren and inhospitable surface.
