Scientists say they have found evidence of dunes of frozen methane on Pluto.
The research, which is published in the journal Science, suggests that the distant world is more dynamic than previously thought.
Pluto's atmosphere was believed to be too thin to create the features familiar in deserts on Earth.
The findings come from analysis of the startling images sent back by Nasa's New Horizons mission, which flew close to Pluto in July 2015.
