Exoplanet WASP-96 b Webb Telescope Data Translated to Sound | NASA
Experience the first full-color images and data from NASA’s James Webb Space Telescope in a brand new way. Webb observed the atmospheric characteristics of the hot gas giant exoplanet WASP-96 b—which contains clear signatures of water—and the resulting transmission spectrum’s individual data points were translated into sound.
Data sonifications support blind and low-vision listeners first, but are designed to be captivating to anyone who tunes in. This sonification, which scans the spectrum from left to right, was adapted to a video to allow sighted viewers to watch the progression as the vertical line moves across the graph, ringing out a musical note for each data point. From bottom to top, the y-axis ranges from less to more light blocked. The x-axis represents wavelength of light, and ranges from 0.6 microns on the left to 2.8 microns on the right. The pitches of each data point correspond to the frequencies of light each point represents. Longer wavelengths of light have lower frequencies and are heard as lower pitches. The volume also indicates the amount of light detected in each data point.
The four water signatures are represented by the sound of water droplets falling. These sounds simplify the data—water is detected as a signature that has multiple data points. The sounds align only to the highest points in the data.
This sonification does not represent sounds recorded in space. Two musicians converted Webb’s transmission spectrum to musical pitches to help listeners hear its data.

Southern Ring Nebula: Webb Telescope Data Translated to Sound | NASA
Experience the first full-color images and data from NASA’s James Webb Space Telescope in a brand new way. In this video, each of Webb's two views of the Southern Ring Nebula—in near-infrared light (at left) and mid-infrared light (at right)—has been adapted to sound.
Sonifications support blind and low-vision listeners first, but are designed to be captivating to anyone who tunes in. This sonification, which scans the images from left to right, was adapted to a video to allow sighted viewers to watch as a vertical line moves across the frame.
Two stars orbit one another at the center of this planetary nebula. The smaller, fainter red star in the mid-infrared image at right is at the end of its lifetime. It has puffed off layers of gas and dust for thousands of years. Its companion, the brighter, larger star in both images, has stirred up those ejections. Now, listeners can hear the stars and surrounding shells of material in each image clearly.
The colors in the images were mapped to pitches of sound, with frequencies of light converted directly to frequencies of sound. Near-infrared light is represented by a higher range of frequencies at the beginning of the track. Mid-way through, the notes change, becoming lower overall to reflect that mid-infrared includes longer wavelengths of light.
Listen carefully at 15 seconds and 44 seconds. These notes align with the centers of the near- and mid-infrared images, where the stars at the center of the “action” appear. In the near-infrared image that begins the track, only one star is heard clearly, with a louder clang. In the second half of the track, listeners will hear a low note just before a higher note, which denotes that two stars were detected in mid-infrared light. The lower note represents the redder star that created this nebula, and the second is the star that appears brighter and larger.
This sonification does not represent sounds recorded in space. Two musicians mapped the telescope’s data to sound, carefully composing music that represents near- and mid-infrared light, specifically to hear their contrasts. In a way, this sonification is like modern dance or an abstract painting—it converts two of Webb’s images into a new medium to engage and inspire listeners.

The Carina Nebula's Cosmic Cliffs: Webb Telescope Data Translated to Sound | NASA
Experience the first full-color images and data from NASA’s James Webb Space Telescope in a brand new way. This data sonification maps a near-infrared image of the Cosmic Cliffs in the Carina Nebula, captured by NASA’s Webb Telescope, to a symphony of sounds. Musicians assigned unique notes to the semi-transparent, gauzy regions and very dense areas of gas and dust in the nebula, culminating in a buzzing soundscape.
Sonifications support blind and low-vision listeners first, but are designed to be captivating to anyone who tunes in. This sonification, which scans the image from left to right, was adapted to a video to allow sighted viewers to watch as a vertical line moves across the frame.
The soundtrack is vibrant and full, representing the detail in this gigantic, gaseous cavity that has the appearance of a mountain range. The Carina Nebula is a large cloud of gas and dust where stars are forming or have already formed.
The gas and dust in the top half of the image are represented in blue hues and windy, drone-like sounds. The bottom half of the image, represented in ruddy shades of orange and red, has a clearer, more melodic composition.
Brighter light in the image is louder. The vertical position of light also dictates the frequency of sound. For example, bright light near the top of the image sounds loud and high, but bright light near the middle is loud and lower pitched. Dimmer, dust-obscured areas that appear lower in the image are represented by lower frequencies and clearer, undistorted notes.
This sonification does not represent sounds recorded in space. Two musicians mapped the telescope’s data to sound, carefully composing music to accurately represent details the team would like listeners to focus on. In a way, this sonification is like modern dance or an impressionist painting—it converts Webb’s image to a new medium to engage and inspire listeners.

This pan video takes a close up look at an image from the Wide Field Imager (WFI) on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. It reveals a cloud of hydrogen and newborn stars called Gum 41 in the constellation of Centaurus (The Centaur). In the middle of this little-known nebula, brilliant hot young stars emit energetic radiation that causes the surrounding hydrogen to glow with a characteristic red hue.

Artist's Impression of the Famous Exoplanet Tau Boötis b | ESO
This video based on an artist's impression shows the exoplanet Tau Boötis b. This was one of the first exoplanets to be discovered back in 1996, and it is still one of the closest planetary systems known to date.
Distance: about 51 light-years away
Astronomers using the European Southern Observatory's Very Large Telescope (VLT) have caught and studied the faint light from the planet Tau Boötis b for the first time. By employing a clever observational trick the team find that the planet's atmosphere seems to be cooler higher up, the opposite of what was expected.

This image of the sky around star Tau Boötis was created from the Digitized Sky Survey 2 images. The star itself, which is bright enough to be seen with the unaided eye, is at the center. The spikes and colored circles around it are artifacts of the telescope and photographic plate used and are not real.
Distance: about 51 light-years away
The exoplanet Tau Boötis b orbits very close to the star and is completely invisible in this picture. The planet has only just been detected directly from its own light using the European Southern Observatory's Very Large Telescope (VLT).

Dark Mattter Map for Galaxy Cluster Abell 1689 | Hubble
This NASA/European Space Agency Hubble Space Telescope image shows the distribution of dark matter in the center of the giant galaxy cluster Abell 1689, containing about 1,000 galaxies and trillions of stars. Abell 1689 resides 2.2 billion light-years from Earth.
Dark matter is an invisible form of matter that accounts for most of the universe's mass. Hubble cannot see the dark matter directly. Astronomers inferred its location by analyzing the effect of gravitational lensing, where light from galaxies behind Abell 1689 is distorted by intervening matter within the cluster.
Researchers used the observed positions of 135 lensed images of 42 background galaxies to calculate the location and amount of dark matter in the cluster. They superimposed a map of these inferred dark matter concentrations, tinted blue, on an image of the cluster taken by Hubble's Advanced Camera for Surveys. If the cluster's gravity came only from the visible galaxies, the lensing distortions would be much weaker. The map reveals that the densest concentration of dark matter is in the cluster's core.
The image was taken in June 2002.

Hubble Uncovers One of the Youngest and Brightest Galaxies in the Early Universe
A massive cluster of yellowish galaxies is seemingly caught in a spider's web of eerily distorted background galaxies in the first image, taken with the Advanced Camera for Surveys (ACS) aboard NASA/European Space Agency Hubble Space Telescope.
The gravity of the cluster's trillion stars acts as a cosmic "zoom lens", bending and magnifying the light of the galaxies located far behind it, a technique called gravitational lensing. The faraway galaxies appear in the Hubble image as arc-shaped objects around the cluster, named Abell 1689. The increased magnification allows astronomers to study remote galaxies in greater detail.
One galaxy is so far away, however, it does not show up in the visible-light image taken with ACS (top, right), because its light is stretched to invisible infrared wavelengths by the Universe's expansion.
Astronomers used Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) and NASA's Spitzer Space Telescope with its Infrared Array Camera (IRAC)—with help from the gravitational lensing cluster—to see the faraway galaxy.
The distant galaxy, dubbed A1689-zD1, appears as a greyish-white smudge in the close-up view taken with Hubble's NICMOS (center, right), and as a whitish blob in the Spitzer IRAC close-up view (bottom, right). The galaxy is brimming with star birth. Hubble and Spitzer worked together to show that it is one of the youngest galaxies ever discovered. Astronomers estimate that the galaxy is 13 billion light-years away. Abell 1689 is 2.2 billion light-years away.
A1689-zD1 was born during the middle of the "dark ages", a period in the early universe when the first stars and galaxies were just beginning to burst to life. The dark ages lasted from about 400,000 to roughly a billion years after the Big Bang. Astronomers think that A1689-zD1 was one of the galaxies that helped end the dark ages.
The ACS images inserted into the first picture were taken in 2002, the NICMOS images in 2005 and 2007, and the Spitzer IRAC images in 2006.
In the second image, the view includes infrared light images from the WFC3 instrument on the NASA/ESA Hubble Space Telescope as well as visible light views. It shows a close up look at part of the rich galaxy cluster Abell 1689. The huge concentration of mass bends light coming from more distant objects and can increase their total apparent brightness and make them visible. One such object, A1689-zD1, appears on this picture as the elongated reddish object in the box.
New observations with ALMA and ESO’s VLT have revealed that A1689-zD1 is a dusty galaxy seen when the Universe was just 700 million years old. Its light has been magnified by a factor of more than nine by the massive gravitational lensing effect of the cluster.
