The U.S. Postal Service is going all out for this summer's total solar eclipse, with a first-of-its kind stamp.
The Total Eclipse of the Sun Forever thermochromic ink stamps may be pre-ordered at usps.com/shop in early June for delivery following the June 20 nationwide issuance. Its new stamps celebrating the eclipse are the first ever to use thermochromic ink that changes the image on the stamp at the touch of a warm finger.
The photo on the Total Eclipse of the Sun Forever stamp is of a total solar eclipse captured in Libya more than a decade ago. As the moon cools, it will gradually return to the eclipse image.
The back of the stamp sheet will include a map of the best places to see the total solar eclipse, which will happen on August 21st -two months from now. 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.
What that means is when your finger touches the stamp when it's black, the image changes to the moon on the the right.

The Aug. 21 eclipse will mark the first time that high-altitude balloons will be used to live-stream video footage of a total solar eclipse. "Partial eclipses or partial phases of total solar eclipses are never safe to watch without solar eclipse glasses". The entire US will get a partial eclipse.
NASA TV and NASA.gov will broadcast a live panel discussion and news conference starting at noon Wednesday. NASA scientists will be available to media at 3 p.m. CDT Wednesday, June 21, at the National Space Science and Technology Center (NSSTC) in Huntsville, Alabama.
Thermochromic inks are vulnerable to UV light and should be kept out of direct sunlight as much as possible to preserve this special effect.
