Touch the Invisible Sky
Multi-wavelength astronomy - the study of the universe at wavelengths beyond the visible, has revolutionized our understanding and appreciation of the cosmos. Hubble, Chandra, and Spitzer are examples of powerful, space-based telescopes that complement each other in their observations spanning the electromagnetic spectrum. NASA's new Braille book "Touch the Invisible Sky" presents the first printed introduction to modern, multi-wavelength astronomy studies to the sight disabled community.

A Universe of Notes:
This audio explanation
of the electromagnetic spectrum makes an analogy between sound and light.
"Touch the Invisible Sky" is accessible to both visually impaired and sighted
readers. The book presents celestial objects as they appear through
visible-light telescopes and in different spectral regions that are
invisible to the naked eye. It uses a combination of Braille and
traditional text. A variety of tactile textures and symbols were
chosen to represent different physical features and characteristics
of the images.
Copies of this book will be supplied free of charge to the US Library
of Congress and other libraries serving the Braille reading population,
as well as to US schools and technology centers for the blind.
Additional copies will be available for purchase through Ozone
This project represents a collaboration among several NASA programs
and three authors. The initial prototype of the book was funded by an
education and public outreach grant from the Chandra X-ray Observatory
to Dr. Mark Lacy at the Spitzer Science Center. Co-authors Noreen Grice
and Doris Daou prepared the draft. Ozone Publishing's unique system of
applying transparent Braille outlines and textures over colored images
was chosen to produce the published copy. Dr. Simon Steel of the Universe
Forum joined the team for final revisions. The Braille and tactile images
were reviewed by Vivial Seki, of Education Service Center, Region 20,
and Benning Wentworth and students at the Colorado School for the Deaf
and Blind. Funds for publication were contributed by the Space Telescope
Science Institute, the Origins Forum, the Universe Forum, the
Chandra X-ray Center, and the Spitzer Science Center.
