Baily's beads

As the Moon covers the Sun during a solar eclipse, the rugged topography of the lunar limb allows beads of sunlight to shine through in some places while not in others.

It is not safe to view Baily's beads or the diamond ring effect without proper eye protection because in both cases the photosphere is still visible.

As the burst of light from the ring fades, Baily's beads appear as the last bits of the bright photosphere shine through valleys aligned at the edge of the Moon.

[9]Before the diamond ring effect during a total solar eclipse, a sequence of small bits of sunlight known as Baily's Beads can be observed.

[10] In 1735, painter and architect Cosmas Damian Asam completed a painting that is probably the earliest known work that realistically depicts a total solar eclipse and diamond ring.

[11] The Diamond Ring effect is seen during the credit opening sequence of Star Trek: Voyager (1995–2001), albeit from a fictitious extrasolar body, as seen from space.
