This photo shows a jagged cliff about a kilometre (0.6 miles) tall on the surface of a distant comet.
It was taken by the European Space Agency's Rosetta spacecraft, which has been orbiting the comet since early August.
The low surface gravity means that a human could probably survive a leap from the top of this cliff. See the photo enlarged here.

Comet probe Philae has started drilling into the surface of the comet which it landed on this Wednesday.
But there may not be enough power left in the craft's depleting batteries to obtain scientific data from the samples it collects.
Philae is believed to be tilted to one side in the shadow of a crater wall and is not getting enough light to recharge its batteries using electricity generated by its solar panels.
With less than 24 hours before the craft's primary battery power runs out, scientists are actively considering taking a last-ditch gamble and "hopping" the lander to a sunnier spot. Read: Scientists debating whether to 'hop' Philae to new spot
Just two years ago a group of Cambridge engineers created the Raspberry Pi - their aim was to make a very cheap computer that youngsters could programme - and learn how it works.
They've since sold almost 4 million of them... And now they've brought out a new version -"the A plus." At just under 20 pounds it's the cheapest computer they've produced.

Scientists have confirmed that Philae, which was built with the help of scientists from our region, is on the surface of a comet more than 300 million miles from earth.
Members of the European Space Agency said the Rosetta probe was operating well, but they don't know for how long.
