On August 21, 2017 the United States experienced its first coast-to-coast total solar eclipse in nearly 100 years. This film follows three teams of astronomers as they seize this rare opportunity to study the sun’s outer atmosphere, its corona, which is only visible during a total eclipse.
On Casper Mountain in Wyoming, one team studies the eclipse to better understand what triggers deadly solar storms that can damage satellites and knock out the power supplies to cities. While in Houston, Texas, two NASA jets, equipped with sun-tracking telescopes, fly into the path of the eclipse to record the sun’s corona.
The scientists behind this experiment are trying to solve a mystery that has puzzled scientists for decades – why the corona is hotter than the sun itself. With stunning CGI graphics and video of the eclipse from all along the eclipse path, Eclipse: Secrets of the Sun provides a dramatic and definitive account of this unique event.
