Katie Paterson is known for conceptual artworks that have involved broadcasting the sounds of a melting glacier live to a visitor on a mobile phone in an art gallery, mapping all the dead stars in the universe, compiling a slide archive of the history of darkness across the ages, custom-making a light bulb to simulate the experience of moonlight, burying a nano-sized grain of sand deep within the Sahara desert, and sending a re-cast meteorite back into space.
