Composition of three images showing the partial stages of the eclipse, finishing with the spectacular Baily's Beads just moments before totality. At the beginning and end of a total solar eclipse, the light from the Sun appears broken up into 'beads', known as 'Baily's Beads' after their discoverer, British astronomer Francis Baily. This phenomenon happens because the edge of the Moon is jagged with mountain peaks. Photograph by Jamie Cooper.
