This is a book funded by NASA to develop a way to let people who cannot see - read what space looks like through their fingers. The book is filled with color images captured from telescopes. Each image is embossed with lines, bumps and texture that denote the the size shape and feel of things shown in the image.
Even the colors are denoted in the textures on the picture... even though they may not be sure of the true empact of the color itself. The pages give them tactile variations in the surface that which allow a sense of what is created by those colors. Then after reading what causes those colors from the brail pages they can get a better understanding of outer space in a way the blind had no possiblity to understand before.
