This Blind Astrophysicist 'Sees' the Universe in the Most Amazing Way

Wanda Diaz-Merced studies the universe through sound. After losing her eyesight in early adulthood, she found a way to continue her work as an astrophysicist by converting scientific data into sound. Through a process known as "sonification," Diaz-Merced listens to the stars to detect patterns in seemingly random astrophysical data. As she says, “If we only see with our eyes, our perception is very narrow.”

In this short from Emic Films, blind astrophysicist Wanda Diaz-Merced explains her passion for listening to the music of the cosmos.
