Video: 00:01:22 An ethereal dance of misty clouds of interstellar dust with a myriad of distant stars and galaxies speckled like paint drops over a black canvas. This is a sonification of a breathtaking image king image taken by ESA's Euclid space telescope of the young star-forming region Messier 78.
The sonification offers a different representation of the data collected by Euclid, and lets us explore the stellar nurseries in M78 through sound. Close your eyes and listen to let the cosmic image be drawn by your mind’s eye, or watch as the traceback line in this video follows the sounds to colour the image from left to right.
The twinkling sounds of various pitches and volumes represent the galaxies and stars in the frame. The pitch of the sound points towards where we see the dot of light in the image. Higher pitches tell us that a star or galaxy appears further at the top in the image along the traceback line.
The brightness of these objects in and around M78 are represented by the volume of the twinkles. Whenever we hear a particularly loud clink, the star or galaxy that Euclid observed appears particularly bright in the image.
Underlying these jingling sounds, we can hear a steady undertone, made up of two chords which represent different regions in Messier 78. This sound intensifies as the traceback line approaches first the brightest, and later the densest regions in the nebula.
The first two deeper crescendos in this undertone indicate two patches in the image where the most intense colour is blue/purple. These appear as two ‘cavities’ in M78, where newly forming stars carve out and illuminate the dust and gas in which they were born.
The chords intensify a third time at a slightly higher pitch corresponding to the red-orange colours in the image, as the sound draws over the densest star-forming region of the frame. This stellar nursery is hidden by a layer of dust and gas that is so thick that it obscures almost all the light of the young stars within it.
As the sound traces over the entire Euclid image, these different tones together form a cosmic symphony that represents the image of Messier 78, and the stars and galaxies that lie behind and within it. You can read more about this image that was first revealed to the eyes of the world earlier this year here.

5 Min Read Hats Off to NASA’s Webb: Sombrero Galaxy Dazzles in New Image
NASA’s James Webb Space Telescope recently imaged the Sombrero galaxy with its MIRI (Mid-Infrared Instrument), resolving the clumpy nature of the dust along the galaxy’s outer ring. Credits:
NASA, ESA, CSA, STScI In a new image from NASA’s James Webb Space Telescope, a galaxy named for its resemblance to a broad-brimmed Mexican hat appears more like an archery target.
In Webb’s mid-infrared view of the Sombrero galaxy, also known as Messier 104 (M104), the signature, glowing core seen in visible-light images does not shine, and instead a smooth inner disk is revealed. The sharp resolution of Webb’s MIRI (Mid-Infrared Instrument) also brings into focus details of the galaxy’s outer ring, providing insights into how the dust, an essential building block for astronomical objects in the universe, is distributed. The galaxy’s outer ring, which appeared smooth like a blanket in imaging from NASA’s retired Spitzer Space Telescope, shows intricate clumps in the infrared for the first time.
Image A: Sombrero Galaxy (MIRI Image)
NASA’s James Webb Space Telescope recently imaged the Sombrero galaxy with its MIRI (Mid-Infrared Instrument), resolving the clumpy nature of the dust along the galaxy’s outer ring. This image includes filters representing 7.7-micron light as blue, 11.3-micron light as green, and 12.8-micron light as red. NASA, ESA, CSA, STScI Image B: Sombrero Galaxy (Hubble and Webb Image)
Image Before/After Researchers say the clumpy nature of the dust, where MIRI detects carbon-containing molecules called polycyclic aromatic hydrocarbons, can indicate the presence of young star-forming regions. However, unlike some galaxies studied with Webb, including Messier 82, where 10 times as many stars are born than the Milky Way galaxy, the Sombrero galaxy is not a particular hotbed of star formation. The rings of the Sombrero galaxy produce less than one solar mass of stars per year, in comparison to the Milky Way’s roughly two solar masses a year.
Even the supermassive black hole, also known as an active galactic nucleus, at the center of the Sombrero galaxy is rather docile, even at a hefty 9-billion-solar masses. It’s classified as a low luminosity active galactic nucleus, slowly snacking on infalling material from the galaxy, while sending off a bright, relatively small, jet.
Also within the Sombrero galaxy dwell some 2,000 globular clusters, collections of hundreds of thousands of old stars held together by gravity. This type of system serves as a pseudo laboratory for astronomers to study stars — thousands of stars within one system with the same age, but varying masses and other properties is an intriguing opportunity for comparison studies.
In the MIRI image, galaxies of varying shapes and colors litter the background of space. The different colors of these background galaxies can tell astronomers about their properties, including how far away they are.
The Sombrero galaxy is around 30 million light-years from Earth in the constellation Virgo.

A Bright Future Ahead
Stunning images like this, and an array of discoveries in the study of exoplanets, galaxies through time, star formation, and our own solar system, are still just the beginning. Recently, scientists from all over the world applied for observation time with Webb during its fourth year of science operations, which begins in July 2025.
General Observer time with Webb is more competitive than ever. A record-breaking 2,377 proposals were submitted by the Oct. 15, 2024, deadline, requesting about 78,000 hours of observation time. This is an oversubscription rate, the ratio defining the observation hours requested versus the actual time available in one year of Webb’s operations, of around 9 to 1.
The proposals cover a wide array of science topics, with distant galaxies being among the most requested observation time, followed by exoplanet atmospheres, stars and stellar populations, then exoplanet systems.
The Space Telescope Science Institute manages the proposal and program selection process for NASA. The submissions will now be evaluated by a Telescope Allocation Committee, a group of hundreds of members of the worldwide astronomical community, on a dual-anonymous basis, with selections announced in March 2025.
While time on Webb is limited, data from all of Webb’s programs is publicly archived, immediately after it’s taken, or after a time of exclusive access, in the Mikulski Archive for Space Telescopes (MAST) so it can be used by anyone in the world.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

NASA’s Instruments Capture Sharpest Image of Earth’s Radiation Belt
From Aug. 19-20, ESA’s (European Space Agency’s) Juice (Jupiter Icy Moons Explorer) mission made history with a daring lunar-Earth flyby and double gravity assist maneuver, a spaceflight first. As the spacecraft zipped past our Moon and home planet, Juice’s instruments came online for a dry run of what they’ll do when they reach Jupiter. During that time, two of NASA’s onboard instruments added another first to the list: capturing the sharpest-ever image of Earth’s radiation belts – swaths of charged particles trapped in Earth’s magnetic shield, or magnetosphere.
The Jovian Energetic Neutrals and Ions (JENI) instrument, built and managed by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, on behalf of NASA, took the image as Juice soared away from Earth. What it captured is invisible to the human eye. Unlike traditional cameras that rely on light, JENI uses special sensors to capture energetic neutral atoms emitted by charged particles interacting with the extended atmospheric hydrogen gas surrounding Earth. The JENI instrument is the newest generation of this type of camera, building on the success of a similar instrument on NASA’s Cassini mission that revealed the magnetospheres of Saturn and Jupiter.

The white rings denote equatorial distance of 4 and 6 Earth radii. The inset showcases measurements taken by the NASA’s JENI and JoEE instruments during their passage through the radiation belts, revealing a highly structured energetic ion and electron environment. Credit: ESA/NASA/Johns Hopkins APL/Josh Diaz “As soon as we saw the crisp, new images, high fives went around the room,” said Matina Gkioulidou, deputy lead of JENI at APL. “It was clear we had captured the vast ring of hot plasma encircling Earth in unprecedented detail, an achievement that has sparked excitement for what is to come at Jupiter.”
On Aug. 19, JENI and its companion particle instrument Jovian Energetic Electrons (JoEE) made the most of their brief 30-minute encounter with the Moon. As Juice zoomed just 465 miles (750 kilometers) above the lunar surface, the instruments gathered data on the space environment’s interaction with our nearest celestial companion. It’s an interaction scientists expect to see magnified at Jupiter’s moons, as the gas giant’s radiation-rich magnetosphere barrels over them.
On Aug. 20, Juice hurled into Earth’s magnetosphere, passing some 37,000 miles (60,000 km) above the Pacific Ocean, where the instruments got their first taste of the harsh environment that awaits at Jupiter. Racing through the magnetotail, JoEE and JENI encountered the dense, lower-energy plasma characteristic of this region before plunging into the heart of the radiation belts. There, the instruments measured the million-degree plasma encircling Earth to investigate the secrets of plasma heating that are known to fuel dramatic phenomena in planetary magnetospheres.
“I couldn’t have hoped for a better flyby,” said Pontus Brandt, principal investigator of JoEE and JENI at APL. “The richness of the data from our deep-dive through the magnetosphere is astounding. JENI’s image of the entire system we just flew through was the cherry on top. It’s a powerful combination we will exploit in the Jovian system.”
Now after using the Moon’s and Earth’s gravity, Juice’s trajectory has been successfully adjusted for a future encounter with Venus in August 2025. That Venus flyby will serve as a gravitational slingshot, propelling Juice back toward Earth and priming it for two additional flybys in September 2026 and January 2029. Only then will the spacecraft, now boosted into high gear, make its grand arrival at Jupiter in July 2031.
The Johns Hopkins Applied Physics Laboratory, in Laurel, Maryland, manages the JoEE and JENI instruments, which together make up the Particle Environment Package (PEP-Hi) instrument suite, for NASA on ESA’s Juice mission. The JoEE and JENI instruments are part of the Solar System Exploration Program, managed at NASA’s Marshall Space Flight Center for the agency’s Science Mission Directorate in Washington.
