The U.S. Postal Service is breaking new ground with a stamp that will be released in conjunction with this summer’s total solar eclipse. The stamp will feature the image of a blacked-out sun that transforms into an image of the moon when the stamp is touched.
The Postal Service says the stamp, which will be released soon, will be the first to employ something called thermochromic ink. For more about the science behind it, please click here.
The eclipse, which will occur on Aug. 21, is said to be the first total eclipse of the sun that will be visible on the U.S. mainland since 1979. It will traverse the entire country for the first time since 1918.
The total solar eclipse provides the only chance to see the sun’s corona without specialized instruments.
