Color blindness
It can be helpful have a plan in advance for color blind students. We suggest for extreme color vision deficiency that such participants could contribute by perhaps researching the astronomical objects included in the activity (see our
"Science" section on the previous page) and reporting on their findings to the class. Or participants with varying degrees of color blindness could be paired carefully with verbal students or classroom volunteers who could help describe the activity with them if they come across any specific aspects of the colorization that present a challenge. We welcome any additional
feedback from educators or students who experience color vision deficiencies and have tried this activity.
Visually Impaired
As part of the "From Earth to the Universe" (FETTU) project, a NASA-funded tactile and Braille poster series for the visually impaired community was launched in 2009. These posters are accessible to both visually impaired and sighted readers. The materials present celestial objects as they appear through visible-light telescopes and in different spectral regions that are invisible to the naked eye. The posters use a combination of Braille and large-format traditional text, and a variety of tactile textures and symbols are shown to represent different physical features and characteristics of the images.
