The Galilean moons are the four largest moons of Jupiter. Galileo Galilei discovered these satellites orbiting Jupiter in 1610. This discovery changed the world by seriously challenging the Ptolemaic system where the Earth is considered stationary and at the center of the universe. Initially named Jupiter IV the fourth Medicean planet, the fourth satellite was later renamed “Callisto”, in Greek mythology one of the lovers of Zeus and daughter of Lycaon, King of Arcadia.

- All art work is handmade by Robert Wiener in the DC Art Glass Studio. Kilnforming is a method of shaping glass in a kiln using heat and gravity. Techniques used by the artist include fusing, slumping, casting, printmaking and coldworking. It is common of kilnformed glass to have slight color shifts and small "champagne" bubbles.
