The European Space Agency made history in November by landing a probe on a comet 500 million km from Earth.

The robot probe Philae has since been hitching a lift on Comet 67P/Churyumov-Gerasimenko as it orbits the Sun.

The comet lander called home from Comet 67P on Saturday, its first contact since running out of battery power shortly after landing some seven months ago.

The robot鈥檚 mothership Rosetta, which dropped the robot on to the 4km-wide icy dirt-ball, is now being moved closer to facilitate a more effective relay.

Currently, the satellite is sitting back from the comet at a distance just above 200km.

The mission has to be cautious, though. Comet 67P is throwing huge quantities of gas and dust into space as its ices melt in the warmth of the Sun.

Here is a quick look at the comet - and what it could teach us - in 60 seconds.
