An eclipse for everyone – how visually impaired students can ‘get a feel for’ eclipses
By Cassandra Runyon, College of Charleston, David Hurd, Pennsylvania Western University
Many people in the U.S. will have an opportunity to witness nearly four minutes of a total solar eclipse on Monday, April 8, 2024, as it moves from southern Texas to Maine. But in the U.S., over 7 million people are blind or visually impaired and may not be able to experience an eclipse the traditional way.
Of course they, like those with sight, will feel colder as the Sun’s light is shaded, and will hear the songs and sounds of birds and insects change as the light dims and brightens. But much of an eclipse is visual.
We are a planetary scientist and an astronomer who, with funding and support from NASA’s Solar System Exploration Research Virtual Institute, have created and published a set of tactile graphics, or graphics with raised and textured elements, on the 2024 total solar eclipse.
The guide, called “Getting a Feel for Eclipses,” illustrates the paths of the 2017 total, 2023 annular and 2024 total solar eclipses. In a total eclipse, the Moon fully blocks the Sun from Earth view, while during an annular eclipse, a narrow ring of sunlight can be seen encircling the Moon.
The tactile graphics and associated online content detail the specific alignment of the Earth, Moon and Sun under which eclipses occur.
To date, we have distributed almost 11,000 copies of this book to schools for the blind, state and local libraries, the Library of Congress and more.
Why publish a tactile book on eclipses?
NASA has lots of explanatory material that helps people visualize and understand rare phenomena like eclipses. But for people with visual impairments, maps and images don’t help. For tactile readers, their sense of touch is their vision. That’s where this guide and our other tactile books come in.
