This stamp image is a photograph taken by retired NASA astrophysicist Fred Espenak of Portal, AZ, who is considered by many to be the world’s leading authority on total solar eclipses with 27 under his belt. The photograph shows a total solar eclipse seen from Jalu, Libya, on March 29, 2006.

“I’m honored to have my images on this unique stamp. But more importantly, the stamp will spread the news about America’s great eclipse to many more people than I could ever reach,” said Espenak, who began collecting eclipse stamps after witnessing his first as a teenager. “A total eclipse of the Sun is simply the most beautiful, stunning and awe-inspiring astronomical event you can see with the naked eye — but you’ve got to be in the 70-mile-wide path of totality that runs across the nation from Oregon to South Carolina. So where will you be on August 21?”

“Having witnessed so many total eclipses myself, I know that two minutes inside the moon’s shadow could have a profound impact on the younger generation,” said Guhathakurta. “The Sun can be viewed safely with the unaided eye only during the few brief seconds or minutes of a total solar eclipse. Partial eclipses or partial phases of total solar eclipses are never safe to watch without solar eclipse glasses.”
