NASA’s Amazing Space project has a monthly Tactile Astronomy feature that provides public-domain files for printing “feelable” versions of Hubble’s deep space photographs on special printers:

Tactile Astronomy supports our efforts to bring the wonders of the universe to everyone, regardless of their visual ability. This new section of Amazing Space includes “Images of the Month” — monthly postings of the latest Hubble images designed to be downloaded and printed on a thermal paper expansion machine, thus allowing the visually impaired to feel what they cannot see.
