Nasa photographs ‘trees’ on Mars
A Nasa probe has sent back photographs of what appears to be trees on the planet’s surface.

The images appear to show rows of dark “conifers” sprouting from dunes and hills on the planet surface. But the scene is actually an optical illusion.
The photographs actually show sand dunes coated with a thin layer of frozen carbon dioxide, or dry ice, less than 240 miles from the planet’s north pole.
The “trees” are really trails of debris caused by landslides as ice melts in Mars’s spring. You can even see a cloud of dust, just to the left of centre of the picture, where an avalanche is caught happening.
The photograph was taken from orbit around Mars by HiRISE, the most powerful camera sent to another planet.
