     In the early 2000s, space probes [confirmed Mars as] having dunes […] Their shapes are identical to their Saharan cousins', but they are ten times bigger. In contrast, underwater dunes are a hundred times smaller than their counterparts on solid ground. This universality of dunes is a blessing for physicists: their comparative study confirmed the models that describe the formation of dunes on Earth.
