The space telescope’s global popularity surely arises, though, not only from its many scientific attainments but also from the spectacular images it has produced of glittering galaxies, softly glowing nebulae, and the wreckage of shattered stars. A quarter century later the cosmic scenes assembled by Zoltan Levay and his colleagues at the Space Telescope Science Institute have, in the words of NASA historian Steven J.
