20"x16" glass and aluminum plaque to commemorate the advancements made to science by Nicolaus Copernicus.

Original plaque went missing during extensive landscape renovations around the Planetarium in the early 2000's.

New plaque was designed and installed at the entrance to the Gordon Southam Observatory.

Glass and aluminum are commonly used materials in the apparatus of modern astronomy research, with glass being the most important material of historical astronomy (Galileo's telescope).

The application of the vinyl to the back surface of the glass set a distance to the engraved aluminum means that the changing direction of the sun causes the shadow of Copernicus to move across his own drawing.
