NASA published a 60 pages book with title “Touch the Invisible Sky” which is destined for visually impaired people! Based on the Braille system and enriched with embossed surfaces, it attempts to give these people the a feel of how the stars and the sky looks like. It has a total of 28 pictures of nebulas, stars and galaxies in high quality. It is a very nice gift for those that see the world in a different way.
