The faster a sound wave travels, the more distance it will cover in the same period of time. In equation form, this is speed = distance/time Since the speed of a wave is defined as the distance that a point on a wave (such as a compression or a rarefaction) travels per unit of time, it is often expressed in units of meters/second (abbreviated m/s). Always be cautious to distinguish between the two often-confused quantities of speed ( how fast.) and frequency ( how often.).

While frequency refers to the number of vibrations that an individual particle makes per unit of time, speed refers to the distance that the disturbance travels per unit of time. Like any wave, the speed of a sound wave refers to how fast the disturbance is passed from particle to particle. As one particle becomes disturbed, it exerts a force on the next adjacent particle, thus disturbing that particle from rest and transporting the energy through the medium.

The rising and falling pitches that can be heard are due to the radar scan passing across the shells and jets in the nebula. The circular rings of the Cat’s Eye create a constant hum, interrupted by a few sounds from spokes in the data.

The X-rays are represented by a harsher sound, while the visible light data sound smoother. Light that is further from the center is heard as higher pitches while brighter light is louder. A radar-like scan of the image emanates from the center point of the nebula and moves clockwise to produce pitch.

This image of the Cat's Eye contains both X-rays from Chandra (around the center) and visible light data from the Hubble Space Telescope, which show the series of bubbles expelled by the star over time. These outbursts can form spectacular structures such as the one seen in the Cat's Eye Nebula. When a star like the Sun begins to run out of helium to burn, it will blow off huge clouds of gas and dust. For more information on this sonification, visit the Chandra Observatory's sonification page. A constant, low hum associated with the bright core can be heard, punctuated by short sounds from compact sources of light within the galaxy. At wavelengths in which the spiral arms are prominent, the pitches creep upward as the spiral reaches farther from the core. The sequence begins with sounds from all four types of light, but then separately moves through the data from Spitzer (infrared), Hubble (visible), GALEX (ultraviolet), and Chandra (x-ray). Each wavelength of light in the image is mapped to a limited range of pitches, from low to high pitch, which corresponds to low to high light frequency: infrared, optical, ultraviolet, and then X-ray. The radius is mapped to notes of a melodic minor scale. The sonification begins at the top of the image and moves radially around the image in a clockwise direction. The Whirlpool Galaxy (M51) is named for its face-on orientation to Earth, which reveals its winding spiral arms. The brightest part of the image corresponds to the loudest portion of the sonification, which is where astronomers find the 6.5-billion solar mass black hole. Radio waves are mapped to the lowest tones, visible data to medium tones, and X-rays to the highest tones. The sonification scans from left to right across the three-tiered image, with each wavelength mapped to a different range of audible tones. The brightest region of the image is where the black hole is found, and the structure ejecting from it is the jet, produced by material falling onto the black hole. This image of a jet emerging from the nucleus of M87 contains three panels that feature: X-rays from the Chandra X-ray Observatory, visible light from Hubble, and radio waves from the Atacama Large Millimeter Array in Chile.

This sonification does not feature the EHT data, but rather looks at data from other telescopes that observed M87 on much wider scales at roughly the same time. Studied by scientists for decades, the black hole in Messier 87 (M87) gained celebrity status after the first release from the Event Horizon Telescope (EHT) project in 2019.
