Fiorella Terenzi is an Italian-born astrophysicist, author and recording artist who is best known for taking recordings of radio waves from far-away galaxies and turning them into music. She received her doctorate from the University of Milan but is currently based in the United States.

Described by Time magazine as "a cross between Carl Sagan and Madonna", Dr. Terenzi has studied opera and composition at Conservatory G. Verdi, Corsi Popolari Serali and taught physics and astronomy at various U.S. colleges and universities; she is currently on the full-time faculty at Florida International University in Miami. In research at the Computer Audio Research Laboratory, University of California, San Diego, she pioneered techniques to convert radio waves emanating from distant galaxies into sound, with some of the results released by Island Records on her acclaimed CD Music from the Galaxies. The goal of her audiofication/sonification of celestial data is to investigate how sound could reflect chemical, dynamical and physical properties of celestial objects, what she calls "Acoustic Astronomy".
