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

Featuring an image captured by NASA’s James Webb Space Telescope, this stamp shows a star cluster approximately 1,000 light-years from Earth. Hidden within the cloud of celestial dust are floating brown dwarfs — objects too small to be stars but larger than most planets. Studying these brown dwarfs will help scientists explore how star-formation processes operate for very small masses. Greg Breeding, an art director for USPS, designed the stamp with an image provided by the National Aeronautics and Space Administration, the European Space Agency, the Canadian Space Agency, the Space Telescope Science Institute, Kevin Luhman (Penn State University) and Catarina Alves de Oliveira (European Space Agency). Upon favorable review by the Postal Regulatory Commission, the stamp will be denominated at the new Priority Mail Express 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.

On January 21, 2025, in Big Sky, MT, the United States Postal Service® will issue the $31.40 Star Cluster Priority Mail Express® stamp, in one design, in a pressure-sensitive adhesive (PSA) pane of four stamps (Item 129400). This stamp will go on sale nationwide January 21, 2025, and must not be sold or canceled before the first-day-of-issue.

This new Priority Mail Express® stamp celebrates America’s continued exploration of deep space with another remarkable image captured by NASA’s James Webb Space Telescope. The stamp features star cluster IC 348, a formation approximately 1,000 light-years from Earth within the constellation Perseus. Hidden within the cloud of celestial dust are tiny, free-floating brown dwarfs — objects too small to be stars but larger than most planets. Studying these brown dwarfs will help scientists explore how star-formation processes operate for very small masses. Art director Greg Breeding designed the stamp with an image provided by NASA (National Aeronautics and Space Administration), ESA (European Space Agency), CSA (Canadian Space Agency), STScI (Space Telescope Science Institute), Kevin Luhman (Penn State University), and Catarina Alves de Oliveira (ESA).
