THE “clearest evidence yet” of an outer space lake has been found on Mars by a NASA rover.

In the foothills of a Martian mountain, NASA’s Curiosity rover found stunning new evidence of an ancient lake in the form of rocks etched with the ripples of waves.

The wave-marked rocks were found about a kilometre into Curiosity’s ascent of Mount Sharp.

The rover has attempted to extract samples from some of the rocks, but they proved too hard for its drill.

Scientists are now hoping Curiosity will stumble on some softer spots more conducive to sample collection as its trek continues.

Curiosity has been exploring Mars for about a decade, and has been climbing the base of Mount Sharp since 2014.
