Wanda Hears the Stars: A Blind Astronomer Listens to the Universe is a 2025 non-fiction picture book written by Wanda Díaz-Merced and Amy S. Hansen and illustrated by Rocio Arreola Mendoza. It follows the story of how Díaz-Merced learned to use sonification, which converts data sets into sound, to continue her research into stars after losing her vision due to diabetes.
A Spanish edition, Wanda oye las estrellas: Una astrónoma ciega escucha al universo, was released the same day as the English book.
Reception Kirkus Reviews gave a positive review, noting the "onomatopoeia-adorned" language and "dark, jewel-toned hues" used to represent the night sky, and concluded the book was "Uplifting and informative". School Library Journal reviewed Wanda oye las estrellas.
The book won the 2026 Schneider Family Book Award for best young children's title. Mathical Books, a website covering children's literature with mathematical themes run by the Simons Laufer Mathematical Sciences Institute, included it in its 2026 Mathical Honor Book list.
