BALTIMORE – NASA will debut a new book for blind readers at a media event and reception Jan. 15. The agency will unveil “Touch the Invisible Sky,” which gives blind readers the ability to experience cosmic images from the agency’s space-based observatories and other telescopes on the ground.
“Touch the Invisible Sky” is accessible to both blind 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.

Don’t let me down again In the immortal words of the Duke himself – “It’s time to kick ass and chew bubble gum. And I’m all out of gum.”
