Listen to the rhythms of the pulsating red giant star called 74 Draconis based on brightness measurements from NASA’s Transiting Exoplanet Survey Satellite. Just below the surfaces of these stars, hot gas rises, cools, and then sinks, where it heats up again, much like a pan of boiling water on a hot stove. This motion produces waves of changing pressure – sound waves. The interaction of these waves results in orderly motion called standing waves that create measurable changes in the star’s brightness. Larger stars produce longer oscillations and thus have deeper tones. To produce audible tones, astronomers multiplied its oscillation frequency by 3 million times.

Messier 104 (M104 for short), located about 28 million light-years from Earth, is one of the largest galaxies in the nearby Virgo cluster. As seen from Earth, the galaxy is angled nearly edge-on allowing a view of its bright core and spiral arms wrapped around it. Spitzer's infrared view of M104 shows a ring of dust circling the galaxy that pierces through the obscuring dust in Hubble’s optical light image. Spitzer also sees an otherwise hidden disk of stars within the dust ring. The Chandra X-ray image shows hot gas in the galaxy and point sources that are a mixture of objects within M104 as well as quasars in the background. The Chandra observations show that diffuse X-ray emission extends over 60,000 light years from the center of the M104. (The galaxy itself spans 50,000 light years across.) In sonifying these data, we can listen to each type of light either separately or together. Either option begins at the top and scans toward the bottom of the image. The brightness controls the volume and the pitch, meaning the brightest sources in the image are the loudest and highest frequencies. The data from the three telescopes are mapped to different types of sounds. The X-rays from Chandra sound like a synthesizer, Spitzer’s infrared data are strings, and optical light from Hubble has bell-like tones. The core of the galaxy, its dust lanes and spiral arms, and point-like X-ray sources are all audible features in the sonification of these data.

Stardust: Passing Comet Tempel 1

This image shows the region around the Milky Way's central supermassive black hole, known as Sagittarius A* (Sgr A*), in infrared (orange and purple) and X-ray light (blue). The image is scanned from left to right and the data are transformed into sound. The brightness of the objects is represented by the volume, while the vertical positions of the sources in the image are mapped to musical pitches. X-rays are played with a soft synthesizer and the infrared data are heard as bass notes and plucked sounds. The brightest region in the middle of the image (and hence the loudest) is where Sgr A* the black hole, resides. It is within this area that the Event Horizon Telescope was able to peer to obtain the first image of Sgr A* itself.
