An annular solar eclipse (like this one imaged by JAXA’s Hinode spacecraft in 2010) happens when the Moon is at its furthest distance from Earth and passes in between the Earth and the Sun, leaving the Sun’s visible outer edges to form a “ring of fire,” or annulus, around the Moon. This kind of eclipse will happen this Sunday, 21 June. The ring of fire will be visible from central Africa and through Asia. Many other locations from southeastern Europe to the northern tips of Australia will experience a partial annular eclipse. Elsewhere, you can watch a live stream of the eclipse.
