NASA scientists have released eerie, Hans Zimmer-like audio from a radar that picked up sounds from a black hole at the center of the Perseus galaxy cluster. The actual sound waves were discovered in data collected by NASA’s Chandra X-ray Observatory and converted from astronomical data into sounds audible to humans. The release coincides with Black Hole Week.
Astronomers found that waves in the hot gas surrounding Perseus’ black hole can be converted into sound.

NASA explained that it’s a common misconception that “no sound can be heard in space” because most of space is a vacuum, leaving no medium for sound waves to propagate. The space agency went on to explain that galaxy clusters consist of abundant gas that envelops hundreds and even thousands of galaxies, providing a medium for the propagation of sound waves.
Corresponding sky news, This sonification differs from previous efforts that simply translated astronomical data into an auditory form using various instruments. This time, the agency re-synthesized the sound waves to match the human hearing range and scaled them up by 57 and 58 octaves above their actual pitch. But these sounds were not imitated with violins or other instruments.
The sound sounds eerily like a score by the well-known composer Hans Zimmer, who, among other things, provided the soundtrack for science fiction hits Bladerunner 2049 and Interstellar.
These sonifications, led by the Chandra X-ray Center (CXC), were part of NASA’s Universe of Learning (UoL) program with support from the Goddard Space Flight Center/Hubble Space Telescope. The collaboration was led by visualization scientist Kimberly Arcand (CXC), musician Andrew Santaguida and astrophysicist Matt Russo (both from the SYSTEMS Sound project). The Chandra program is managed by NASA’s Marshall Space Flight Center.
