Euclid telescope prepares for voyage to create largest 3D map of the cosmos

European Space Agency's 1bn probe will travel 1m miles from Earth to shed light on dark universe

Final preparations are under way to launch a space telescope that aims to produce the largest, most accurate 3D map of the cosmos and unravel the dark forces that shape it.

The European Space Agency's 1bn (862m) Euclid probe will observe more than a third of the sky and billions of galaxies to shed light on the mysterious dark matter and dark energy that together account for 95% of the universe.
