These USPS Eclipse stamps are so cool I’m willing to stand in line at the Post Office. I’ve been a little underwhelmed by forever stamps lately but these Eclipse stamps go the extra mile by offering up a thermo chromatic magic trick. Which basically means they change when you rub them. Direct from the Post Office:
Eclipse stamps are the first-of-its-kind Forever stamp which transforms the solar eclipse image into the Moon from the heat of a finger. The Total Eclipse of the Sun Forever stamp commemorates the upcoming Aug. 21 eclipse.
The pane of 16 Forever stamps are available at Post Office facilities nationwide and may be pre-ordered now at this link for delivery after June 20.
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) passing through portions of 14 states.
A total solar eclipse provides us with the only chance to see the Sun’s corona — its extended outer atmosphere — without specialized instruments. During the total phase of an eclipse the corona appears as a gossamer white halo around the black disk of the Moon, resembling the petals of a flower reaching out into space.
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 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.
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.
