Star Cluster Stamps 2025

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).
