Pictures of an eclipse have been taken on Mars by the NASA rover Curiosity.
The pictures show Phobos, the larger of Mars' two moons, passing in front of the sun, images released on Thursday show.
Curiosity landed on Mars in August 2012 for a two-year mission.
The pictures were taken on 17 August with a telephoto lens. Three photos taken three seconds apart were issued by NASA on Thursday.
This one is by far the most detailed image of any Martian lunar transit ever taken," said scientist Mark Lemmon of Texas AM University in a statement.
