The European Space Agency (Esa) says its comet lander, Philae, has woken up and contacted Earth.

Philae, the first spacecraft to land on a comet, was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November.

It worked for 60 hours before its solar-powered battery ran flat.

The comet has since moved nearer to the sun and Philae has enough power to work again, says the BBC's science correspondent Jonathan Amos.

The probe tweeted the message, "Hello Earth! Can you hear me?"

Jean-Yves Le Gall, the president of France's CNES space agency, told AFP that Philae had sent signals for a period of two minutes "as well as 40 seconds worth of data".
