Baily's beads
- Eclipses and Transits
Baily's beads are features of total and annular solar eclipses, caused when the Moon's uneven limb lets sunlight pass through valleys while blocking it elsewhere. They are named for Francis Baily, who explained the effects in 1836. When only one or two beads remain, they can form a diamond ring effect around the Moon's silhouette. They are brief and must not be viewed without proper eye protection.
