Explore: Wallal Expedition Centennial Talk

In 1918 Albert Einstein developed the Theory of General Relativity and four years later in September 1922, a small Station in Western Australia called Wallal just happened to be in the perfect place to attempt to prove this theory.

1922 saw a total solar eclipse happening right above Wallal and scientists from observatories and universities across the globe set off on one of the major scientific expeditions in W.A history.

Perth Observatory was one of the groups that went on this expedition, along with the University of Western Australia, and one of the telescopes brought with them was the Calver, a telescope still used by the public today.

Learn more about this expedition, what it meant for astronomy and Einstein’s Theory, and the role Perth Observatory played, through a talk from Perth Observatory volunteer Arthur Harvey. Stay late and have a look through our Calver telescope, or book in on a special tour on the days leading up to the talk to get to look through our Calver telescope and get taken back 100 years in astronomical history.
