A Ring of Fire: The 2012 Annular Eclipse
Yesterday, the Moon passed between the Sun and Earth, casting its shadow from China to North America. This was an annular eclipse, where the Moon's apparent diameter is slightly smaller than the Sun's, blocking all but a ring of sunlight. Skywatchers brought out special glasses, welder's masks, and telescopes to safely view this relatively rare event. Some were lucky enough to look down and see overlapping pinhole projections of the eclipse as the sunlight streamed through the leaves of nearby trees. Gathered here, for those who weren't able to see it in person, is a group of images of yesterday's annular eclipse.
