NASA introduced a new book, "Touch the Invisible Sky," at a ceremony at the National Federation of the Blind. Images of nebulae, stars, and galaxies from the Hubble Space Telescope, Chandra X-ray Observatory, Spitzer Space Telescope, and ground-based telescopes are brought to the fingertips of the blind. Each image is embossed with lines, bumps, and textures that translate colors, shapes, and other intricate details of the cosmic objects. Braille and large-print descriptions accompany each image, making the book accessible to readers of all visual abilities.

"Touch the Invisible Sky" introduces the concept of light and the spectrum and explains how the different observatories complement each others' findings. It was written by Noreen Grice of the Museum of Science, Boston; Simon Steel, an astronomer with the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA; and Doris Daou, an astronomer at NASA Headquarters, Washington.

"About 10 million visually impaired people live in the United States," Grice said. "I hope this book will be a unique resource for people who are sighted or blind to better understand the part of the universe that is invisible to all of us." The book will be available through NASA libraries, the National Federation of the Blind, Library of Congress repositories, libraries, museums, and Ozone Publishing.
