English astronomer Francis Baily first discovered and described Baily’s beads – a phenomenon that occurs in the seconds before and after totality in a total solar eclipse and annularity in an annular solar eclipse. The first photograph of the Sun’s corona was taken by a Prussian photographer called Berkowski.
The total solar eclipse of June 8, 1918 crossed the United States from Washington State to Florida. This path is roughly similar to the August 21, 2017 total solar eclipse and was the last time totality crossed the nation from the Pacific to the Atlantic.
