The universe can now be felt, as well as seen, thanks to a new book that translates the mostly invisible wavelengths of the universe into Braille and embossed textures.

Some suggest a tactile representation of the universe might bring a deeper understanding of it

The book Touch the Invisible Sky, by Noreen Grice, has been unveiled by the US National Federation of the Blind and NASA.

It blends written text, Braille, astronomical images and embossed textures to recreate stars, galaxies and other cosmic objects as observed through some of the world's most advanced telescopes.

"It totally levels the playing field," Grice says. "Most of the light in the universe is not visible to our eyes."

So it makes no difference whether you represent celestial scenes made by x-rays, infrared or ultraviolet light as a false-colour photograph or in a tactile way.
