Solar Eclipse Postage Stamps Change With The Touch Of Your Finger!

solar eclipse postage stamps are interactive

The new “Total Eclipse of the Sun” U.S. postage stamps designed by Antonio Alcalá, and using real photos from a former Astrophysicist, are the very first to use Thermochromic ink, which reacts to the heat of your touch. Placing your finger over the black disc on the stamp causes the ink to change from black to clear to reveal an underlying image of the moon.

The Total Eclipse of the Sun stamp is being issued as a Forever® stamp and will always be equal in value to the current First-Class Mail® one-ounce price.

What Is Thermochromic Ink?
The Total Eclipse of the Sun stamp is the first U.S. stamp to use thermochromic ink, which reacts to the heat of your touch. (You may recall that we published a very interesting post about a table made with Thermochromic inks here) Placing your finger over the black disc on the stamp causes the ink to change from black to clear to reveal an underlying image of the moon. The image reverts back to the black disc once it cools.

Where did the photos for the stamps come from?

Retired American Astrophysicist Fred Espenak with his solar telescope

Astrophysicist Fred Espenak (who is referred to as “Mr. Eclipse”) photographed both images for the stamp that commemorates the total solar eclipse of August 21, 2017 that crosses the USA.

The stamp uses a photograph, above, taken by astrophysicist Fred Espenak of a total solar eclipse that was seen over 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. 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.” – Fred Espenak

Mr. Espenak (who is known as Mr. Eclipse) also took the photograph of the full moon, shown below, that is revealed by pressing upon the stamp image from his observatory in Portal, Arizona in 2010.

The reverse side of the stamp pane shows the path across the United States of the forthcoming August 21, 2017, total solar eclipse and gives the times that it will appear in some locations.

The back of the stamp pane provides a map of the August 21 eclipse path and times it may appear in some locations. Visit NASA’s website to view detailed maps of the eclipse’s path.

About The Solar Eclipse

On August 21, 2017, tens of millions of people in the United States will have an opportunity to view a total eclipse of the Sun. A total solar eclipse was last seen on the U.S. mainland in 1979, but only in the Northwest. The eclipse this summer will sweep a narrow path across the entire country—the first time this has happened since 1918. The U.S. Postal Service® anticipates this rare event with a stamp celebrating the majesty of solar eclipses.

A total eclipse of the Sun occurs when the Moon completely blocks the visible solar disk from view, casting a shadow on Earth. The 70-mile-wide shadow path of the eclipse, known as the “path of totality,” will traverse the country diagonally, appearing first in Oregon (mid-morning local time) and exiting some 2,500 miles east and 90 minutes later off the coast of South Carolina (mid-afternoon local time).

A total solar eclipse provides us with the only chance to see the Sun’s corona—its extended outer atmosphere—without specialized instruments. The corona during an eclipse looks like a gossamer white halo around a black disk, or like the petals of a flower reaching out into space.
