NASA’s latest project, “A Universe of Sound,” is revolutionizing the way we experience astronomy data through a new sensory channel – sound. By converting publicly available data from its Chandra X-ray Observatory and other observatories into dozens of “sonifications,” NASA aims to make complex astronomical concepts more accessible to everyone.
The project, inspired by the open science principle of accessibility, uses sonification to help visually impaired individuals experience NASA’s data in a new way. However, sighted users also enjoy listening to the sonifications, which are designed to enhance the data outputs themselves.
Dr. Kimberly Arcand, lead scientist and visualization expert at Chandra, explains that “sonification is just one of those steps” towards making scientific data more inclusive. The team uses various musical instruments or synthesized sounds to represent different wavelengths of observation from different telescopes, such as X-rays, infrared, and visual light.
For example, a sonification of the supernova remnant Cassiopeia A features modified piano sounds for X-ray data, strings and brass for infrared data, and small cymbals for stars detected by visual light. The team’s goal is not only to create accessible data but also to promote collaboration and reproducibility in scientific research.
By involving a diverse range of community members, including scientists, audio engineers, and individuals with disabilities, NASA ensures that the project adds value to the greater good and makes investments in data worthwhile.
The “Listen to the Universe” documentary is available on NASA+, while all sonifications can be accessed on the Universe of Sound website. This innovative project showcases the power of open science in enhancing scientific discovery and making it more inclusive for everyone.
