Spencer Finch’s impressive light installation Moon Dust (Apollo 17), first presented at the 2009 Venice Biennale, will illuminate The Baltimore Museum of Art's majestic Fox Court for the next seven years.
The work consists of 150 individual chandeliers with 417 lights. The chandeliers are hung individually from the ceiling and form one large, cloud-like structure. Although an abstract sculpture, the installation is also a scientifically precise representation of the chemical composition of moon dust as it was gathered during the Apollo 17 mission. Finch translated the diagrams of the chemical formulas of the contained molecules by using light bulbs in different diameters and basic customary fixtures with different arm lengths to create a three-dimensional scale model of the moon’s atomic makeup. The diameter of a globe corresponds to the size of an atom and thus represents a specific element, the small globes representing helium, the bigger oxygen.
