Making Astronomy Accessible to the Blind – Students Partner with Professionals to Build New Software Tool


Application Deadline April 23, 2017 – 11:59 PM


If intelligent life without sight exists on some distant planet in our galaxy, these lifeforms would still explore the universe; how? This is a guiding question for Innovators Developing Accessible Tools for Astronomy (IDATA), a new research initiative supported by the U.S. National Science Foundation – STEM + Computing Partnerships (STEM+C) Program.

During a visit to Yerkes Observatory, students from the Wisconsin Center for the Blind and Visually Impaired explore 3D printing and how the sense of touch can be used to explore astronomical images. Through the IDATA project, students from the Center and elsewhere across the U.S., will work with a team of professionals to design and develop Afterglow Access, a new software tool that will expand accessibility beyond touch, making the universe more accessible to those with visual impairments.

You might remember seeing those early images from the Hubble Space Telescope? Spectacular pillars of greenish gas and dust giving birth to new stars and planets, incredibly detailed spiral arms in galaxies millions of light-years away, but not once did you look through the telescope and see these images with your own eyes. Today, these amazing astronomical images are generated by computers with light gathered from distant objects using telescopes and a variety of detectors. This light is converted into numerical data and computers use that data to generate the images we see. In reality, we are all “blind” to this data, we choose to convert these numbers into images. What if we turned it into sound or something we could feel through touch? If a picture is worth a thousand words, how much is a song worth?

Modern astronomy relies on computers and computational thinking for nearly every aspect of collecting, analyzing, and presenting data. Visual interfaces commonly used for these computational processes present unique challenges for blind and visually impaired (BVI) individuals. While BVI individuals are severely underrepresented across all fields of science, technology, engineering, and mathematics (STEM), the lack of vision-neutral tools in astronomy further increase the barrier-to-entry for BVI individuals.

Research suggests that astronomy topics, participation in authentic scientific research, exploration of astronomy topics, and experience with computer science as a part of broader applications of STEM can be powerful motivators for individuals to pursue STEM learning and career opportunities. IDATA project investigators from Associated Universities Inc., University of Chicago – Yerkes Observatory, TERC – STEM Education Evaluation Center, University of Nevada – Las Vegas, and Skynet at University of North Carolina – Chapel Hill,  hypothesize that teaming up BVI and sighted students, teachers, and professionals in the design and development of astronomy software and instructional modules will result in more accessible tools for astronomy investigations, powerful educational experiences, and lower the barrier-to-entry for BVI (and all) individuals interested in astronomy and related careers.

Over the next three years the project team will engage BVI and sighted students and their teachers from both mainstream and specialized schools for the blind in the project. Annually IDATA engages 20 teachers and 200 grades eight through twelve students in the project. While half of the participating schools will be located in Southern Wisconsin and the Chicago area, the remaining schools will be selected from across the United States and its territories.

IDATA students and teachers will participate in user-centered design/universal design (UCD/UD) processes to iteratively developing and testing software and learning modules, improving the accessibility for educational and professional uses of astronomy tools. The project builds on the success of prior NSF supported research, including the development of Afterglow, the Quorum programming language, and the Skynet Junior Scholars portal that supports collaborative astronomy investigations with the Skynet international network of telescopes.

The research will advance knowledge about students’ learning related to computational thinking, the role of computation in astronomy, and software design, as well as how participation influences students’ attitudes and beliefs about who can engage in STEM and computing. The accessible software and instructional modules produced in this study may be adopted by a range of BVI and sighted individuals, but may also be transferrable to other similarly visually-intensive domains such as satellite, geophysical, and medical imaging.

Recruitment of schools, including teachers and students, is expected to begin late March 2017. For more information or to receive updated news about IDATA, please contact IDATA project PI Tim Spuck at [email protected], or IDATA Project Educator Kate Meredith at [email protected], or sign up at
