Rosetta beams back stunning photo of cliff on comet

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.

Philae begins drilling into surface of comet

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.

An image of the Philae lander on the comet's surface.

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

Engineers hope to make coding as easy as Pi

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.
