As predicted by VSC, the USPS announced a new Priority Mail stamp on December 16^th:

USPS celebrates the continued exploration of deep space with an extremely high-definition image of a spiral galaxy 32 million light-years from Earth. The image, captured by NASA’s James Webb Space Telescope, helps researchers update their models of star formation and allows them to better understand the origins of our universe. Greg Breeding, an art director for USPS, designed the stamp with an image from the National Aeronautics and Space Administration, the European Space Agency, the Canadian Space Agency, the Space Telescope Science Institute, Janice Lee (Space Telescope Science Institute), Thomas Williams (Oxford) and the Physics at High Angular resolution in Nearby GalaxieS Team. Upon favorable review by the Postal Regulatory Commission, the stamp will be denominated at the new Priority Mail Flat Rate Envelope rate.

The stamp will be issued January 21 in Big Sky, Montana, with a “local ceremony.” Additional information will be posted below the line, with the most recent information at the top.
