Transform New Eclipse Stamp with Finger Touch

Transform New Eclipse Stamp with Finger Touch

The U.S. Postal Service is going all out for this summer's total solar eclipse, with a first-of-its kind stamp.

The U.S. Postal Service is issuing a one-of-a-kind stamp Tuesday ahead of the coast-to-coast, total eclipse set to appear on August 21.

The stamp image is a photograph taken by astrophysicist Fred Espenak, nicknamed Mr. Eclipse, that shows a total solar eclipse seen from Jalu, Libya, on March 29, 2006.

Press your thumb to the new stamp and its dark eclipse image will turn into the moon.

Everybody is so excited about this event, since it is the total solar eclipse visible on the territory of the United States since 1979. The postage stickers are printed with thermochromatic ink, letting snail mailers and stamp enthusiasts change the front image with the swipe of a finger.

More than half a million people - and possibly as many as 2 million - will flock to SC to see the eclipse. Eclipse watchers in north Alabama will see a partial eclipse, weather permitting, with the moon covering about 97 percent of the sun's disk. This means that when someone touches it, their body heat will create a reaction that changes the circular eclipse image from black to clear and reveal a moon image beneath.

"A total eclipse of the Sun is simply the most attractive, 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 OR to South Carolina", Espenak said.

On Monday, USPS announced it would debut a special forever stamp: "Total Eclipse of the Sun".

The pane of 16 Forever stamps are available Tuesday at Post Office facilities nationwide.

On the back of the stamp, people will find a map depicting the path the eclipse follows and the states where it will be visible. The next time a total solar eclipse will be visible from the US, according to Espanak's website, is April 8, 2024. At the same time with the summer solstice celebration, the stamp will receive an issuing ceremony held at the Art Museum of University of Wyoming.
