Chandra X-ray Observatory | Quick Look: 'Listen' to the Light Echoes From a Black Hole @ChandraXray | Uploaded 1 year ago | Updated 1 hour ago
A new sonification turns X-ray “light echoes” from a black hole into sound.

Rings of X-rays seen by NASA’s Chandra and Swift observatories show the echoes.

Material around a black hole can generate bursts of X-rays.

The X-rays reflect off clouds of gas and dust like beams from headlights can in fog.

$Data Sonification: R Aquarii (Multiwavelength) Astronomers often look at objects in space through multiple telescopes. Because different telescopes can detect different types of light, each brings its own pieces of information to whatever is being observed. This is similar in some ways to how different notes of the musical scale can be played together to create harmonies that are impossible with single notes alone. In the past few years, NASA has been producing “sonifications” of astronomical data of objects in space. This project takes the digital data captured by its telescopes in space — most of which is invisible to our unaided eyes — and translates them into musical notes and sounds so they can be heard rather than seen. Each layer of sound in these sonifications represents particular wavelengths of light detected by NASA’s Chandra X-ray Observatory, James Webb Space Telescope, Hubble Space Telescope, and Spitzer Space Telescope in various combinations. R Aquarii: The system called R Aquarii contains two stars – a white dwarf and a red giant – in orbit around each other. In a composite visual image, Hubble data (red and blue) reveal spectacular structures that are evidence of outbursts generated by the pair of stars buried at the center of the image. X-rays from Chandra show a jet from the white dwarf banging into the material surrounding it and creating shock waves. In the sonification of R Aquarii, the piece evolves as a radar-like scan of the image, clockwise starting at the 12 o’clock position. The volume changes in proportion to the brightness of sources in Hubble’s visible light and Chandra’s X-ray image, while the distance from the center dictates the musical pitch (higher notes are farther out). The deep thuds toward the four corners are “diffraction spikes,” which are artifacts from the bright central star. Listeners can hear jets from the white dwarf as the cursor travels near the two o’clock and eight o’clock positions. The ribbon-like arcs captured by Hubble create a rising and falling melody that sounds similar to a set of singing bowls (metal bowls that produce different sounds and tones when struck with a mallet), while the Chandra data are rendered to sound more like a synthetic and These sonifications were led by the Chandra X-ray Center (CXC) and included as part of NASAs Universe of Learning (UoL) program. The collaboration was driven by visualization scientist Kimberly Arcand (CXC), astrophysicist Matt Russo, and musician Andrew Santaguida (both of the SYSTEM Sounds project).

Each layer of sound in these sonifications represents particular wavelengths of light detected by NASA’s Chandra X-ray Observatory, James Webb Space Telescope, Hubble Space Telescope, and Spitzer Space Telescope in various combinations. Stephans Quintet: In Stephan’s Quintet, four galaxies move around each other, held together by gravity, while a fifth galaxy sits in the frame but is actually at a much different distance. A visual image of Stephan’s Quintet contains infrared light from the James Webb Space Telescope (red, orange, yellow, green, and blue) with additional data from the Spitzer Space Telescope (red, green, and blue) and X-ray light from Chandra (light blue). A sonification of these data begins at the top and scans the image downward. As the cursor moves, the pitch changes in relationship to the brightness in different ways. The background galaxies and foreground stars in the visual images Webb detects are mapped to different notes on a synthetic glass marimba. Meanwhile, stars with diffraction spikes are played as crash symbols. The galaxies of Stephan’s Quintet themselves are heard as smoothly changing frequencies as the scan passes over them. The X-rays from Chandra, which reveal a shock wave that has superheated gas to tens of millions of degrees, are represented by a synthetic string sound.
