With thrilling cosmic clockwork, the moon will pass in front of the sun Monday, casting a 70-mile-wide shadow that will sweep across the United States from coast to coast, giving millions along the “path of totality” a chance to marvel at one of nature’s grandest spectacles, a total eclipse of the sun.
As skywatchers and scientists converge on a transcontinental band of totality for Monday’s solar eclipse in the United States, engineers in Europe are building a unique pair of satellites to create artificial eclipses lasting for hours — a feat that that could be a boon for solar physicists but will escape the view of Earth-bound spectators.
The International Space Station’s crew will enjoy views of the Aug. 21 solar eclipse during three successive orbits, giving the astronauts a unique opportunity to take in the celestial show from 250 miles up as the moon’s shadow races across from the Pacific Ocean and the continental United States before moving out over the Atlantic.
