Blind astrophysicist Enrique Pérez has developed a device that allows blind and visually impaired people to experience solar eclipses through sound. This innovation, part of the Astroaccesible project at the Instituto de Astrofísica de Andalucía (IAA), aims to make astronomy accessible to everyone.
Who is Enrique Pérez?
Enrique Pérez is an astrophysicist at the IAA and the driving force behind Astroaccesible. He is blind and has dedicated his career to making astronomy inclusive. His work ensures that phenomena like solar eclipses are not limited to those who can see.

How Does the Device Work?
The device uses sonification—converting data into sound—to represent changes in light and temperature during an eclipse. As the eclipse progresses, users hear variations in pitch and tone, allowing them to perceive the event audibly.
Other Senses in Play
Blind individuals can also feel the drop in temperature, changes in wind, and animal behavior during an eclipse. These sensory cues, combined with sonification, create a multi-sensory experience. The background to this story is set out in Making British Countryside Accessible and Inviting for All. A related thread runs through Solar Eclipse in Cornwall: A Magical Communal Experience. Earlier coverage in Solar Eclipse Night: Cloudy Skies Still a Phenomenon shows how the argument developed.
Projects Making Astronomy Accessible
Astroaccesible is not alone. In Spain, Lightsound, designed in the US and introduced by ICE, UAB, and IAC, also uses sonification for accessibility. Both projects share the goal of making astronomy inclusive. A closer look at the same subject appears in Solar Eclipse Communal Magic: Cornwall's Skyward Moment. Anyone following the wider picture can start with Europe Solar Eclipse 2026: Rare Spectacle Draws Millions.

Why It Matters
Inclusivity in science is crucial. By making eclipses accessible, we ensure that everyone can participate in the wonder of the cosmos. This fosters a more inclusive scientific community.

FAQ
What is sonification?
Sonification is the process of converting data or information into sound. In the context of astronomy, it allows blind and visually impaired people to perceive celestial events through audio cues.
Can blind people really experience a solar eclipse?
Yes, through a combination of sonification devices and sensory changes like temperature drops and wind shifts, blind individuals can experience an eclipse in a meaningful way.
What is the Astroaccesible project?
Astroaccesible is an initiative by the Instituto de Astrofísica de Andalucía to make astronomy accessible to everyone, particularly through the work of blind astrophysicist Enrique Pérez.
Are there other similar projects?
Yes, Lightsound is another project that uses sonification for accessibility, introduced in Spain by ICE, UAB, and IAC.
