The World by Gaia @ Norton Priory

Measuring 6 metres in diameter, Gaia features 120dpi detailed NASA imagery of the Earth's surface.
The artwork provides the opportunity to see our planet on this scale, floating in three-dimensions.

The artwork is 2.1 million times smaller than the real Earth with each centimetre of the internally lit sculpture describing 21km of the Earth's surface. By standing 181m away from the artwork, the public will be able to see the Earth as it appears from the moon.
Unlike the moon, which we have been gazing at for millennia, the first time humankind got to see the Earth in its entirety as a blue marble floating in space was in 1972 with NASA's Apollo 17 mission.
