TESTING 3-D TACTILE HUBBLE IMAGES.
These images show people with visual impairments using their fingers to explore 3-D tactile representations of images taken by NASA's Hubble Space Telescope.
In these representations, stars, filaments, gas, and dust shown in Hubble
images of the bright star cluster NGC 602 have been transformed
through 3-D printing into textures, appearing as raised open circles,
lines, and dots in the 3-D printout. These features also have different heights to correspond with their brightness. The tallest, and therefore brightest, features are a tight group of open circles, which represent the stars in the core of the cluster.
