In 1922, the eyes of the world were focused on an expedition of international and Australian scientists to Wallal, Australia. The conditions in this remote corner of Western Australia were ideal for photographing a total eclipse that was due on 21 September 1922. The photographic images taken during this ground-breaking expedition allowed for the precise measurements of the apparent position of the stars near the eclipsed Sun. This gave scientists the evidence that proved Albert Einstein’s revolutionary Theory of General Relativity! Discover a moment in history.
