The United States Postal Service has a new stamp to highlight the occasion of a solar eclipse traveling across the United States on August 21

This year on August 21, the United States gets the opportunity to witness the moon completely blocking the sun to create a total solar eclipse, an event that has not happened in 38 years. To help celebrate this event the United States Postal Service (USPS) issued a new stamp of a black circle that reveals the bright moon when touched.

The first layer of the stamp features an image of a total eclipse that was taken by astrophysicist Fred Espenak, an event that happened in Libya in 2006. By using thermachromic printing and temperature-sensitive inks, the warmth of a person’s finger activates the black circle to reveal the image of a full moon underneath. The back of the sheet of stamps showcases a map showing the solar eclipse’s 70-mile journey across the United States.

The stamps go on sale on June 20 and will get labeled as ‘forever’ stamps.
