1. BAILY'S BEADS:1. BAILY'S BEADS:Baily's beads (often spelled Bailey's beads) are bead-like Baily's beads (often spelled Bailey's beads) are bead-like bursts of light that appear about 15 seconds before and after bursts of light that appear about 15 seconds before and after totality during a solar eclipse. Baily's beads are caused by totality during a solar eclipse. Baily's beads are caused by light shining through valleys on the edge of the light shining through valleys on the edge of the moonmoon. They . They were named for the British astronomer Francis Baily (1774-were named for the British astronomer Francis Baily (1774-1844), one of the founders of the Royal Astronomical Society.1844), one of the founders of the Royal Astronomical Society.
