Fred and Pat Espenak are eclipse-chasers and have been for years. They have been leading friends and fans who are eclipse-obsessed on tours around the world to see some of the greatest syzygial moments of our time. I haven't made one of these trips yet -- but will some day.
NASA has officially acknowledged Fred as the world's leading eclipse authority.
Fred Espenak is Scientist Emeritus for Goddard Space Flight Center, and a retired NASA astrophysicist. He is known throughout the world for his work on eclipse predictions and blogs at MrEclipse.com. His website lists dates and times for future solar eclipses through the year 2020.
This pic above was taken by Fred and his wife Pat -- they work together -- during the recent May 20th eclipse about which Fred writes here.
