Last week's question:

When is the next total solar eclipse on Earth after the one on August 21, 2017?

Answer:

The answer will be revealed next week.

Question from the week before:

Just before totality in a solar eclipse, the sun is blocked except for sunlight streaming through lunar valleys along the limb. Who are these brief, bright “beads” of light named after?

“Baily’s Beads” are named for British astronomer Francis Baily who observed and explained them in 1836.
