This is one of two stamps celebrating NASA’s James Webb Space Telescope, the largest, most powerful, and most complex telescope ever put in space.

A  Priority Mail Express stamp, it features Webb’s Near-Infrared Camera (NIRCam) image of the “Cosmic Cliffs” in the Carina Nebula, located roughly 7,600 light-years away. The image shows emerging stellar nurseries and individual stars that were previously hidden from sight. This scene was one of the first full-color images revealed from Webb in July 2022, demonstrating the telescope’s ability to peer through cosmic dust and shed new light on how stars form.
