On 8 April, a total solar eclipse will cross North America from sea to shining sea—from Mexico’s Pacific coast to Canada’s Atlantic Maritimes. Scientists and skywatching enthusiasts are ready for the event with projects and programs to follow the Moon’s shadow—and you can follow them with Katherine Kornei’s “Eclipse Science Along the Path of Totality.” But you don’t need to be a researcher to be starstruck by the spectacle, as Kate Evans explains in “The Small Self and the Vast Universe: Eclipses and the Science of Awe.” If you’re in North America, grab Eos and a pair of eclipse-viewing glasses. If you’re too far away to view this eclipse, visit Eos.org, and scan your social feeds for surprise and delight.
