Discover RED: Eye of the Eclipse

During the afternoon of April 8, the sky over much of Arkansas will darken, as a total solar eclipse moves diagonally over North America. Thousands of people have made plans to observe the eclipse in the so-called totality zone, which in Arkansas is a wide swath running roughly from DeQueen in the southwest to Pocahontas in the northeast. In the latest Discover: RED video, Daniel Kennefick, professor of physics and a researcher at the Arkansas Center for Space and Planetary Sciences, explains why total solar eclipses are so special.
