- Three new Chandra sonifications of data of Jupiter, Saturn, and Uranus have been released.
- Planets and other Solar System bodies can reflect X-rays given off by the Sun, which Chandra can detect.
- Sonification is a process that translates data captured by Chandra and other telescopes into sound.
- In addition to X-rays from Chandra, these new sonifications contain data from Hubble, Cassini, and Keck telescopes.
In late February, people in the Northern Hemisphere can look up for a special sight: Six planets will all be visible from clear and dark night skies. New sonifications from NASA’s Chandra X-ray Observatory released Wednesday will help commemorate this latest “planetary parade.”
Because the planets in our solar system travel around the Sun in the same plane (known as the ecliptic), they will sometimes appear bunched together in the sky when their orbits find them on the same side of the Sun at the same time. When this happens, it looks like the planets have roughly formed a line from our vantage point on Earth.
In Chandra’s sonifications, which translate astronomical data into sound, three of the planets that will be on display — Jupiter, Saturn, and Uranus — can be seen and heard in ways that they cannot from Earth.
While Chandra is best known for its X-ray insight into black holes and other extreme objects, the telescope has also played an important role in the exploration of our solar system. The Sun gives off X-rays that travel out into the solar system and can be reflected by planets, moons, and other bodies. This gives astronomers a unique window into certain physics that cannot be discovered through other kinds of telescopes.
The sonification of Jupiter combines X-ray data from Chandra with an infrared image from NASA’s Hubble Space Telescope. Woodwind sounds reveal Chandra’s X-ray data, including emission from the planet’s auroras. More instruments join in to represent the planet’s complex cloud layers. Next, through the combination of an optical image from NASA’s Cassini mission and X-rays from Chandra, listeners can experience Saturn like never before. A siren-like sound follows the arc of the rings, and different tones of synthesizers play as the scan passes the planet itself. Finally, listeners can hear the ice giant Uranus through the data collected by Chandra and the W.M. Keck Observatory. The data in this sonification reflects the amount of light detected from the planet and the orientation of its ring.
The process of creating a sonification preserves the integrity of the data, which arrives on Earth as a series of ones and zeroes (binary code), and shifts it into a form that can be processed through hearing. Sonifications expand options for people to explore what telescopes discover in space, an example of NASA’s ongoing commitment to share its data as widely as possible.

Jupiter:
In this image, the amount of diffuse X-rays from a donut-shaped ring of energetic particles around Jupiter, seen on the left and right side of the planet, has been enhanced compared to the amount of X-rays from the planet's auroras, seen at the poles. As the scan moves left to right, it encounters X-rays that bracket the planet on either side, and this plays as woodwind sounds. As we pass over the planet itself, seen in an infrared image from NASA’s Hubble Space Telescope, the sounds become fuller as the infrared data is represented by other instruments. Since Jupiter is tilted slightly, the pitch descends as the scan passes over the bright band near the equator and through the Great Red Spot. On the other side, more X-ray data from Chandra flanks the planet and can be heard as gusty wind sounds at the end.
Saturn:
The scan of Saturn begins on the right and moves to the left. As it encounters Saturn’s famous rings, seen in an optical image from the Cassini mission, listeners hear a siren effect whose frequency follows the arc of the rings. Once the scan reaches the planet itself, the sounds change, to lower tones with a dark synthetic bass sound. This distinguishes the rings from the planet. Chandra’s X-rays are heard as higher synthetic tones that mark where high-energy activity is found across the planet, rings, and poles.
Uranus:
Returning to the left to right scan, the sounds begin with a cello that traces the arcing ring — not as famous as Saturn’s but still prominent — around the ice giant Uranus. The notes change to represent the amount of reflected light and its location on Uranus as seen in an optical light image from the W.M. Keck Observatory. The X-rays detected by Chandra, which come from X-rays from the Sun that are reflected, are heard as higher frequencies as the scan passes over the pinkish region of the planet. The apparent asymmetry in the X-rays may not be a real effect because of the faint signal and the smoothing that was applied to the image.

Visual Description:
This release features three sonifications, each focusing on a different planet in our solar system. The sonifications are presented as soundtracks to short videos. Each video features a composite image and
an activation line. As the activation line sweeps across the image, it encounters visual elements. These elements are translated into sound, or sonified, according to parameters established by Chandra's sonification team.
The first sonification focuses on the planet Jupiter. At the center of the associated composite image is the gas giant itself; a seemingly perfect sphere with an atmosphere of latitudinal bands. The bands are different shades of grey, brown, and black, each with its own texture and width. Flanking Jupiter are neon pink and white clouds, representing X-rays from energetic particles in a ring around the planet. In the video, the activation line moves from our left to right. It first encounters a pink cloud, triggering whooshing woodwinds. When the activation line encounters Jupiter, dramatic low notes are triggered. Listen for the dip as the line passes over the Great Red Spot in Jupiter's southern hemisphere. The activation line continues toward our right, passing more pink X-ray clouds. The largest cloud, the last one encountered, has a bright white core, which translates to loud gusty woodwinds.
The second sonification focuses on the ringed planet, Saturn. In the composite image, the large gas giant fills the frame, its spherical outer layer a pale sandy grey. In this image, the wide bands of rings surrounding the planet are in shades of pale grey and sandy yellow. Here, Saturn is tilted away from us, making the round rings appear oval in shape. Dotting the planet are small pockets of neon blue. These represent reflected X-ray light observed by Chandra. In this video, the activation line moves from our right to left. When the line passes over the rings, a whooshing sounds spreads, conveying the widening middle of the oval shapes. Pockets of neon blue X-ray light trigger synthesizer sounds, with the pitch mapped to each pocket's vertical position in the image. When the line sweeps across Saturn's large round body, a low rumbling synth tone is triggered. The volume is linked to brightness, such that the low tone fades when the line reaches the shady side of the planet, on our left.
The third sonification features the planet Uranus. In the composite image, the icy giant is a greenish-blue cyan color, with a blush of neon pink X-rays hovering over its core. Uranus has a collection of very narrow rings, much finer than the wide disk-like rings surrounding Saturn. In this image, the fine rings are near vertical and slightly tilted, creating an oval shape with rounded points at our lower left and upper right. In this sonification, the activation line moves from our left to right. Brightness is mapped to volume and height is mapped to pitch, such that brighter objects at the top of the image sound louder and higher. Here, the curved oval shape of the rings is conveyed as a swooping cello note, with the pitch sliding up as the activation line passes the oval tilted toward our upper right.
