High above a small church near Vienna, Austria, clouds and the Moon vied for position in front of the Sun. Such was the case on the ground late last month during a partial eclipse of the Sun visible throughout Europe and Asia. Nearing the farthest part of its orbit around the Earth, the Moon's angular size was too small to block the entire Sun, a situation that would have resulted in a total solar eclipse. The next solar eclipse visible from Earth will occur on November 23. Although a total eclipse will be visible only from parts of Antarctica, parts of the Sun will momentarily disappear for observers across Australia, New Zealand, and the southernmost tip of South America.
