To space and beyond

[Jimbuna]

This could send back information that changes many a solar map.

Europe has launched the Gaia satellite - one of the most ambitious space missions in history.

The 740m-euro (£620m) observatory lifted off from the Sinnamary complex in French Guiana at 06:12 local time (09:12 GMT).

Gaia is going to map the precise positions and distances to more than a billion stars.

This should give us the first realistic picture of how our Milky Way galaxy is constructed.

Gaia's remarkable sensitivity will lead also to the detection of many thousands of previously unseen objects, including new planets and asteroids.
