Learn about the upcoming total solar eclipse at a user-friendly science talk by international physics and astronomy expert Dr. Jim Brau.
On August 21, in just ninety-one minutes, the sixty-five mile wide path of the Moon's shadow on Earth will pass through Oregon and twelve other states on its way to the Atlantic Ocean. Totality, when the moon blocks the entire sun, will begin on the Oregon coast at about 10:15 a.m. and end in South Carolina. Within the path of totality, the sun's light will be totally blocked for about two minutes and thecorona, the faint surrounding aura of plasma, will appear around the moon's shadow on the sun.
This is an unusual opportunity, as Oregon has experienced a total solar eclipse only twice in the last century, and only over small portions of the state each time. The last one in Oregon, in 1979, ran along the northern state border.
Dr. Brau is the Philip H. Knight Professor of Natural Science and Director of Center for High Energy Physics at the University of Oregon. An expert in particle physics, he also teaches astronomy. His research is supported by the Office of Science of the Department of Energy and the National Science Foundation. Brau is a member of the ATLAS Collaboration studying high energy physics at the Large Hadron Collider, and the LIGO Scientific Collaboration, where he searches for gravitational waves at the LIGO Observatories.
