Satellite will make a 3D map of the Milky Way

Waiting for Video...
 
 

A satellite partly built in Portsmouth will be used to make a 3D map of the galaxy.

The scientific satellite Gaia, designed and built by Astrium, including its base in Hilsea, Portsmouth, will be used to map objects in the Milky Way.

The Gaia mission is also expected to discover hundreds of thousands of unknown celestial objects, including extra-solar planets and failed stars, known as brown dwarfs.

And within our solar system, Gaia will be able to identify tens of thousands of asteroids.

The European Space Agency has released this video explaining what the satellite will be capable of, and how it will work.
