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.

The telescope and instruments for NASA’s Nancy Grace Roman Space Telescope were recently integrated together on the observatory’s instrument carrier at the agency’s Goddard Space Flight Center in Greenbelt, Md. Next, the entire system will be joined to the Roman spacecraft. NASA/Chris Gunn NASA’s Nancy Grace Roman Space Telescope team has successfully integrated the mission’s telescope and two instruments onto the instrument carrier, marking the completion of the Roman payload. Now the team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will begin joining the payload to the spacecraft.
“We’re in the middle of an exciting stage of mission preparation,” said Jody Dawson, a Roman systems engineer at NASA Goddard. “All the components are now here at Goddard, and they’re coming together in quick succession. We expect to integrate the telescope and instruments with the spacecraft before the year is up.”
Engineers first integrated the Coronagraph Instrument, a technology demonstration designed to image exoplanets — worlds outside our solar system — by using a complex suite of masks and active mirrors to obscure the glare of the planets’ host stars.
Then the team integrated the Optical Telescope Assembly, which includes a 7.9-foot (2.4-meter) primary mirror, nine additional mirrors, and their supporting structures and electronics. The telescope will focus cosmic light and send it to Roman’s instruments, revealing billions of objects strewn throughout space and time. Roman will be the most stable large telescope ever built, at least 10 times more so than NASA’s James Webb Space Telescope and 100 times more than the agency’s Hubble Space Telescope. This will allow scientists to make measurements at levels of precision that can answer important questions about dark energy, dark matter, and worlds beyond our solar system.
Technicians install the primary instrument for NASA’s Nancy Grace Roman Space Telescope, called the Wide Field Instrument (at left), in the biggest clean room at the agency’s Goddard Space Flight Center in Greenbelt, Md. This marked the final step to complete the Roman payload, which also includes a Coronagraph instrument and the Optical Telescope Assembly.NASA/Chris Gunn With those components in place, the team then added Roman’s primary instrument. Called the Wide Field Instrument, this 300-megapixel infrared camera will give Roman a deep, panoramic view of the universe. Through the Wide Field Instrument’s surveys, scientists will be able to explore distant exoplanets, stars, galaxies, black holes, dark energy, dark matter, and more. Thanks to this instrument and the observatory’s efficiency, Roman will be able to image large areas of the sky 1,000 times faster than Hubble with the same sharp, sensitive image quality.
“It would be quicker to list the astronomy topics Roman won’t be able to address than those it will,” said Julie McEnery, the Roman senior project scientist at NASA Goddard. “We’ve never had a tool like this before. Roman will revolutionize the way we do astronomy.”
The telescope and instruments were mounted to Roman’s instrument carrier and precisely aligned in the largest clean room at Goddard, where the observatory is being assembled. Now, the whole assembly is being attached to the Roman spacecraft, which will deliver the observatory to its orbit and enable it to function once there.
At the same time, the mission’s deployable aperture cover — a visor that will shield the telescope from unwanted light — is being joined to the outer barrel assembly, which serves as the telescope’s exoskeleton.
“We’ve had an incredible year, and we’re looking forward to another one!” said Bear Witherspoon, a Roman systems engineer at NASA Goddard. “While the payload and spacecraft undergo a smattering of testing together, the team will work toward integrating the solar panels onto the outer barrel assembly.”
That keeps the observatory on track for completion by fall 2026 and launch no later than May 2027.

The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems Inc. in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.

Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster. Their characteristics reveal that new galaxies are forming in these large cosmic cities, with the finding that gravitational interactions in these dense regions are not as important as previously thought.
