Transit of VenusIn 1882, the transit of Venus across the sun was photographed on a series of glass plate negatives made by Amherst College astronomer David Peck Todd. He used a solar photographic telescope (made by the renowned optical firm Alvan Clark & Sons) stationed on the summit of Mount Hamilton, California, where the Lick Observatory was under construction. Of the photos, 147 survived, having been archived in the mountain vault. A century later, they were retrieved and an animation made from them premiered at the International Astronomical Union's general assembly in Sydney in Jul 2003. This is perhaps the most complete surviving record of a historical transit of Venus, dating from the time when Chester Arthur was president of the United States. |
