Description: "The Astonomer" (Tim Wetherell, 2005) -- a statue at Questacon, Australia's national science centre, in Canberra; made from the azimuth ring and other parts of the Yale-Columbia Refractor (telescope) (c 1925) wrecked by the 2003 Canberra bushfires which burned out the Mount Stromlo Observatory. The statue depicts an astronomer of an earlier age measuring the changing angles of stars over time during the annual rotation of the Earth around the Sun, thus estimating the Astronomical Unit, and the distance to nearby stars (Cosmic distance ladder).
