Scientist Emeritus, NASA’s GSFC, Mr. Eclipse
Predicting and Chasing Solar Eclipses
A total eclipse of the Sun is arguably the most spectacular astronomical phenomenon visible to the naked eye. Scientists welcome the eerie darkness brought on by these rare events as a unique opportunity to study the sun’s outer atmosphere the solar corona.
What is it like to witness a total eclipse? How often do eclipses occur and where can they be seen? Fred Espenak has spent over four decades chasing eclipses around the world. He will share his experiences with us through photos and video, including some of his most recent expeditions to Libya and China. The next total eclipse through the USA occurs on August 21, 2017. Details of this exciting event will also be presented along with a preview of the next total eclipse in Canada on April 8, 2024.
