The Great American Total Solar Eclipse 2017 is arriving on August 21 and will be one of the most visible eclipses sweeping across the United States mainland in nearly 40 years.
With a veritable storm of commemorative eclipse merchandise sure to rain down upon consumers this summer, the U.S. Post Office is joining the party and marking the occasion with a cool heat-activated stamp that changes when in contact with the warmth of your finger. This transforming Forever Stamp uses a special thermochromic ink on the eclipse image that reacts to your body heat to reveal a second picture of the shining moon. The stamp's shimmering total eclipse image is a shot captured by astrophysicist Fred Espenak, aka Mr. Eclipse, during totality in Jalu, Libya, on March 29, 2006.
Here's the official press release:
The Postal Service will soon release a first-of-its-kind stamp that changes when you touch it. The Total Solar Eclipse Forever stamp, which commemorates the August 21 eclipse, transforms into an image of the Moon from the heat of a finger. The public is asked to share the news on social media using the hashtag #EclipseStamps.
Tens of millions of people in the United States hope to view this rare event, which has not been seen on the U.S. mainland since 1979. The eclipse will travel a narrow path across the entire country for the first time since 1918. The path will run west to east from Oregon to South Carolina and will include portions of 14 states.
The June 20, 1:30 p.m. MT First-Day-of-Issue ceremony will take place at the Art Museum of the University of Wyoming in Laramie. The University is celebrating the summer solstice on June 20.
Will you stock up on these illuminating total solar eclipse stamps before bathing in the moon's shadow and where will you be watching the Great American Eclipse this summer?
