Luke Jerram's Gaia, a seven-metre Earth made from NASA imagery, hung in the nave of Southwark Cathedral in autumn 2024. What it was, why it was shown in a church, and what it cost to see.

Luke Jerram’s Gaia, the world-renowned miniaturized planet Earth that tours across the globe, is back in London this summer, at the Kensington and Chelsea Festival. The internally-lit spherical sculpture is a helium-filled balloon 2.1 million times smaller than the real Earth. The artwork measures seven metres in diameter and it was created from detailed 120dpi NASA images of the surface of the Earth, as though seen from space.
