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.
