Thousands of Indonesians witnessed a rare celestial event on Tuesday night: a total eclipse of the sun.
The moon passes between Earth and the sun every month, but a total solar eclipse happens only when the three celestial bodies are perfectly aligned. And this particular eclipse was even more spectacular, because it occurred while the moon was at its closest point to Earth, appearing as a large “supermoon” to those on terra firma.
The moon casts its dark central shadow, called the umbra, onto a very narrow strip along the surface of the Earth. The total eclipse is visible only to people standing within that shadowed strip. This week's total eclipse was visible mostly over a stretch of the Pacific Ocean, but also fell across parts of Indonesia.
Skywatchers on some Pacific islands and in Alaska were able to see at least a partial eclipse. If you missed it, no worries: our gallery of images from around the world give you the best seat in the house.
