A colorful ring of material encircling a dying star. Sky-high pillars of dust and gas that serve as incubators for embryonic stars. NASA's Hubble Space Telescope has brought the beauty of space to the living rooms of the world. Named in honor of famous American astronomer Edwin Powell Hubble, the Earth-orbiting observatory's name has become synonymous with space discovery. Now the U.S. Postal Service is paying tribute to Hubble, the astronomer, and Hubble, the telescope, by offering five stamps bearing spectacular Hubble images — Eagle Nebula, Ring Nebula, Lagoon Nebula, Egg Nebula, and Galaxy NGC 1316. The stamp pane's selvage image is a 1949 black-and-white photograph of Edwin Hubble posing with the 48-inch Schmidt Telescope at Palomar Observatory.
