In July 2022, NASA’s James Webb Space Telescope made its public debut with a series of breathtaking images. Among them was an ethereal landscape nicknamed the Cosmic Cliffs. This glittering realm of star birth is the subject of a new 3D visualization derived from the Webb data. The visualization, created by NASA’s Universe of Learning and titled “Exploring the Cosmic Cliffs in 3D,” breathes new life into an iconic Webb image.

It is being presented today at a special event hosted by the International Planetarium Society to commemorate the 100th anniversary of the first public planetarium in Munich, Germany.

The landscape of “mountains” and “valleys” known as the Cosmic Cliffs is actually a portion of the nebula Gum 31, which contains a young star cluster called NGC 3324. Both Gum 31 and NGC 3324 are part of a vast star-forming region known as the Carina Nebula Complex.

Ultraviolet light and stellar winds from the stars of NGC 3324 have carved a cavernous area within Gum 31. A portion of this giant bubble is seen above the Cosmic Cliffs. (The star cluster itself is outside this field of view.)

The Cliffs display a misty appearance, with “steam” that seems to rise from the celestial mountains. In actuality, the wisps are hot, ionized gas and dust streaming away from the nebula under an onslaught of relentless ultraviolet radiation.

Eagle-eyed viewers may also spot particularly bright, yellow streaks and arcs that represent outflows from young, still-forming stars embedded within the Cosmic Cliffs. The latter part of the visualization sequence swoops past a prominent protostellar jet in the upper right of the image.

Produced for NASA by the Space Telescope Science Institute (STScI) with partners at Caltech/IPAC, and developed by the AstroViz Project of NASA’s Universe of Learning, this visualization is part of a longer, narrated video that provides broad audiences, including youth, families, and lifelong learners, with a direct connection to the science and scientists of NASA’s Astrophysics missions. That video enables viewers to explore fundamental questions in science, experience how science is done, and discover the universe for themselves.

“Bringing this amazing Webb image to life helps the public to comprehend the three-dimensional structure inherent in the 2D image, and to develop a better mental model of the universe,” said STScI’s Frank Summers, principal visualization scientist and leader of the AstroViz Project.

More visualizations and connections between the science of nebulas and learners can be explored through other products produced by NASA’s Universe of Learning including a Carina Nebula Complex resource page and ViewSpace, a video exhibit that is currently running at almost 200 museums and planetariums across the United States. Visitors can go beyond video to explore the images produced by space telescopes with interactive tools now available for museums and planetariums.

NASA’s Universe of Learning materials are based upon work supported by NASA under award number NNX16AC65A to the Space Telescope Science Institute, working in partnership with Caltech/IPAC, Center for Astrophysics | Harvard & Smithsonian, and NASA’s Jet Propulsion Laboratory.

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 Universe of Learning is part of the NASA Science Activation program, from the Science Mission Directorate at NASA Headquarters.

Craving an ice cream sundae with a cherry on top? This random alignment of Herbig-Haro 49/50 — a frothy-looking outflow from a nearby protostar — with a multi-hued spiral galaxy may do the trick. This new composite image combining observations from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) provides a high-resolution view to explore the exquisite details of this bubbling activity.

Herbig-Haro objects are outflows produced by jets launched from a nearby, forming star. The outflows, which can extend for light-years, plow into a denser region of material. This creates shock waves, heating the material to higher temperatures. The material then cools by emitting light at visible and infrared wavelengths.

When NASA's retired Spitzer Space Telescope observed it in 2006, scientists nicknamed Herbig-Haro 49/50 (HH 49/50) the “Cosmic Tornado” for its helical appearance, but they were uncertain about the nature of the fuzzy object at the tip of the “tornado.”  With its higher imaging resolution, Webb provides a different visual impression of HH 49/50 by revealing fine features of the shocked regions in the outflow, uncovering the fuzzy object to be a distant spiral galaxy, and displaying a sea of distant background galaxies.

HH 49/50 is located in the Chamaeleon I Cloud complex, one of the nearest active star formation regions in our Milky Way, which is creating numerous low-mass stars similar to our Sun. This cloud complex is likely similar to the environment that our Sun formed in. Past observations of this region show that the HH 49/50 outflow is moving away from us at speeds of 60-190 miles per second (100-300 kilometers per second) and is just one feature of a larger outflow.

Webb’s NIRCam and MIRI observations of HH 49/50 trace the location of glowing hydrogen molecules, carbon monoxide molecules, and energized grains of dust, represented in orange and red, as the protostellar jet slams into the region. Webb’s observations probe details on small spatial scales that will help astronomers to model the properties of the jet and understand how it is affecting the surrounding material.

The arc-shaped features in HH 49/50, similar to a water wake created by a speeding boat, point back to the source of this outflow. Based on past observations, scientists suspect that a protostar known as Cederblad 110 IRS4 is a plausible driver of the jet activity. Located roughly 1.5 light-years away from HH 49/50 (off the lower right corner of the Webb image), CED 110 IRS4 is a Class I protostar. Class I protostars are young objects (tens of thousands to a million years old) in the prime time of gaining mass. They usually have a discernable disk of material surrounding it that is still falling onto the protostar. Scientists recently used Webb’s NIRCam and MIRI observations to study this protostar and obtain an inventory of the icy composition of its environment.

These detailed Webb images of the arcs in HH 49/50 can more precisely pinpoint the direction to the jet source, but not every arc points back in the same direction. For example, there is an unusual outcrop feature (at the top right of the main outflow) which could be another chance superposition of a different outflow, related to the slow precession of the intermittent jet source. Alternatively, this feature could be a result of the main outflow breaking apart.

The galaxy that appears by happenstance at the tip of HH 49/50 is a much more distant, face-on spiral galaxy. It has a prominent central bulge represented in blue that shows the location of older stars. The bulge also shows hints of “side lobes” suggesting that this could be a barred-spiral galaxy. Reddish clumps within the spiral arms show the locations of warm dust and groups of forming stars. The galaxy even displays evacuated bubbles in these dusty regions, similar to nearby galaxies observed by Webb as part of the PHANGS program.

Webb has captured these two unassociated objects in a lucky alignment. Over thousands of years, the edge of HH 49/50 will move outwards and eventually appear to cover up the distant galaxy.

Want more? Take a closer look at the image, “fly through” it in a visualization, and compare Webb’s image to the Spitzer Space Telescope’s.

Herbig-Haro 49/50 is located about 625 light-years from Earth in the constellation Chamaeleon.

For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA’s James Webb Space Telescope’s Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area (seen at the upper left) of this young, nearby star-forming region.

Astronomers found an intriguing group of protostellar outflows, formed when jets of gas spewing from newborn stars collide with nearby gas and dust at high speeds. Typically these objects have varied orientations within one region. Here, however, they are slanted in the same direction, to the same degree, like sleet pouring down during a storm.

The discovery of these aligned objects, made possible due to Webb’s exquisite spatial resolution and sensitivity in near-infrared wavelengths, is providing information into the fundamentals of how stars are born.

“Astronomers have long assumed that as clouds collapse to form stars, the stars will tend to spin in the same direction,” said principal investigator Klaus Pontoppidan, of NASA’s Jet Propulsion Laboratory in Pasadena, California. “However, this has not been seen so directly before. These aligned, elongated structures are a historical record of the fundamental way that stars are born.”

So just how does the alignment of the stellar jets relate to the rotation of the star? As an interstellar gas cloud crashes in on itself to form a star, it spins more rapidly. The only way for the gas to continue moving inward is for some of the spin (known as angular momentum) to be removed. A disk of material forms around the young star to transport material down, like a whirlpool around a drain. The swirling magnetic fields in the inner disk launch some of the material into twin jets that shoot outward in opposite directions, perpendicular to the disk of material.

In the Webb image, these jets are signified by bright clumpy streaks that appear red, which are shockwaves from the jet hitting surrounding gas and dust. Here, the red color represents the presence of molecular hydrogen and carbon monoxide.

“This area of the Serpens Nebula – Serpens North – only comes into clear view with Webb,” said lead author Joel Green of the Space Telescope Science Institute in Baltimore. “We’re now able to catch these extremely young stars and their outflows, some of which previously appeared as just blobs or were completely invisible in optical wavelengths because of the thick dust surrounding them.”

Astronomers say there are a few forces that potentially can shift the direction of the outflows during this period of a young star’s life. One way is when binary stars spin around each other and wobble in orientation, twisting the direction of the outflows over time.

Stars of the Serpens

The Serpens Nebula, located 1,300 light-years from Earth, is only one or two million years old, which is very young in cosmic terms. It’s also home to a particularly dense cluster of newly forming stars (~100,000 years old), seen at the center of this image. Some of these stars will eventually grow to the mass of our Sun.

“Webb is a young stellar object-finding machine,” Green said. “In this field, we pick up sign posts of every single young star, down to the lowest mass stars.” “It’s a very complete picture we’re seeing now,” added Pontoppidan. 

So, throughout the region in this image, filaments and wisps of different hues represent reflected starlight from still-forming protostars within the cloud. In some areas, there is dust in front of that reflection, which appears here with an orange, diffuse shade.

This region has been home to other coincidental discoveries, including the flapping “Bat Shadow,” which earned its name when 2020 data from NASA’s Hubble Space Telescope revealed a star’s planet-forming disk to flap, or shift. This feature is visible at the center of the Webb image.

Future Studies

The new image, and serendipitous discovery of the aligned objects, is actually just the first step in this scientific program. The team will now use Webb’s NIRSpec (Near-Infrared Spectrograph) to investigate the chemical make-up of the cloud.

The astronomers are interested in determining how volatile chemicals survive star and planet formation. Volatiles are compounds that sublimate, or transition from a solid directly to a gas, at a relatively low temperature – including water and carbon monoxide. They’ll then compare their findings to amounts found in protoplanetary disks of similar-type stars.

“At the most basic form, we are all made of matter that came from these volatiles. The majority of water here on Earth originated when the Sun was an infant protostar billions of years ago,” Pontoppidan said. “Looking at the abundance of these critical compounds in protostars just before their protoplanetary disks have formed could help us understand how unique the circumstances were when our own solar system formed.”

These observations were taken as part of General Observer program 1611. The team’s initial results have been accepted for publication in the Astrophysical Journal.

NASA's Webb Snaps Supersonic Outflow of Young Star

HH 211 (NIRCam Image)

Release Images

---

Herbig-Haro (HH) objects are luminous regions surrounding newborn stars, formed when stellar winds or jets of gas spewing from these newborn stars form shock waves colliding with nearby gas and dust at high speeds. This image of HH 211 from NASA’s James Webb Space Telescope reveals an outflow from a Class 0 protostar, an infantile analog of our Sun when it was no more than a few tens of thousands of years old and with a mass only 8% of the present-day Sun. (It will eventually grow into a star like the Sun.)

Infrared imaging is powerful in studying newborn stars and their outflows, because such stars are invariably still embedded within the gas from the molecular cloud in which they formed. The infrared emission of the star’s outflows penetrates the obscuring gas and dust, making a Herbig-Haro object like HH 211 ideal for observation with Webb’s sensitive infrared instruments. Molecules excited by the turbulent conditions, including molecular hydrogen, carbon monoxide, and silicon monoxide, emit infrared light that Webb can collect to map out the structure of the outflows.

The image showcases a series of bow shocks to the southeast (lower-left) and northwest (upper-right) as well as the narrow bipolar jet that powers them. Webb reveals this scene in unprecedented detail — roughly 5 to 10 times higher spatial resolution than any previous images of HH 211. The inner jet is seen to “wiggle” with mirror symmetry on either side of the central protostar. This is in agreement with observations on smaller scales and suggests that the protostar may in fact be an unresolved binary star.

Earlier observations of HH 211 with ground-based telescopes revealed giant bow shocks moving away from us (northwest) and moving towards us (southeast) and cavity-like structures in shocked hydrogen and carbon monoxide respectively, as well as a knotty and wiggling bipolar jet in silicon monoxide. Researchers have used Webb’s new observations to determine that the object’s outflow is relatively slow in comparison to more evolved protostars with similar types of outflows.

The team measured the velocities of the innermost outflow structures to be roughly 48-60 miles per second (80 to 100 kilometers per second). However, the difference in velocity between these sections of the outflow and the leading material they’re colliding with — the shock wave — is much smaller. The researchers concluded that outflows from the youngest stars, like that in the center of HH 211, are mostly made up of molecules, because the comparatively low shock wave velocities are not energetic enough to break the molecules apart into simpler atoms and ions.

Webb Snaps Highly Detailed Infrared Image of Actively Forming Stars

Young stars are rambunctious!

NASA’s James Webb Space Telescope has captured the “antics” of a pair of actively forming young stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center: The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars.

The most striking details are the two-sided lobes that fan out from the actively forming central stars, represented in fiery orange. Much of this material was shot out from those stars as they repeatedly ingest and eject the gas and dust that immediately surround them over thousands of years.

When material from more recent ejections runs into older material, it changes the shape of these lobes. This activity is like a large fountain being turned on and off in rapid, but random succession, leading to billowing patterns in the pool below it. Some jets send out more material and others launch at faster speeds. Why? It’s likely related to how much material fell onto the stars at a particular point in time.

The stars’ more recent ejections appear in a thread-like blue. They run just below the red horizontal diffraction spike at 2 o’clock. Along the right side, these ejections make clearer wavy patterns. They are disconnected at points, and end in a remarkable uneven light purple circle in the thickest orange area. Lighter blue, curly lines also emerge on the left, near the central stars, but are sometimes overshadowed by the bright red diffraction spike.

All of these jets are crucial to star formation itself. Ejections regulate how much mass the stars ultimately gather. (The disk of gas and dust feeding the stars is small. Imagine a band tightly tied around the stars.)

Now, turn your eye to the second most prominent feature: the effervescent blue cloud. This is a region of dense dust and gas, known both as a nebula and more formally as a Bok globule. When viewed mainly in visible light, it appears almost completely black – only a few background stars peek through. In Webb’s crisp near-infrared image, we can see into and through the gauzy layers of this cloud, bringing a lot more of Herbig-Haro 46/47 into focus, while also revealing a deep range of stars and galaxies that lie well beyond it. The nebula’s edges appear in a soft orange outline, like a backward L along the right and bottom.

This nebula is significant – its presence influences the shapes of the jets shot out by the central stars. As ejected material rams into the nebula on the lower left, there is more opportunity for the jets to interact with molecules within the nebula, causing them both to light up.

There are two other areas to look at to compare the asymmetry of the two lobes. Glance toward the upper right to pick out a blobby, almost sponge-shaped ejecta that appears separate from the larger lobe. Only a few threads of semi-transparent wisps of material point toward the larger lobe. Almost transparent, tentacle-like shapes also appear to be drifting behind it, like streamers in a cosmic wind. In contrast, at lower left, look beyond the hefty lobe to find an arc. Both are made up of material that was pushed the farthest and possibly by earlier ejections. The arcs appear to be pointed in different directions, and may have originated from different outflows.

Take another long look at this image. Although it appears Webb has snapped Herbig-Haro 46/47 edge-on, one side is angled slightly closer to Earth. Counterintuitively, it’s the smaller right half. Though the left side is larger and brighter, it is pointing away from us.

Over millions of years, the stars in Herbig-Haro 46/47 will fully form – clearing the scene of these fantastic, multihued ejections, allowing the binary stars to take center stage against a galaxy-filled background.

Webb can reveal so much detail in Herbig-Haro 46/47 for two reasons. The object is relatively close to Earth, and Webb’s image is made up of several exposures, which adds to its depth.

Herbig-Haro 46/47 lies only 1,470 light-years away in the Vela Constellation.

From our cosmic backyard in the solar system to distant galaxies near the dawn of time, NASA’s James Webb Space Telescope has delivered on its promise of revealing the universe like never before in its first year of science operations. To celebrate the completion of a successful first year, NASA has released Webb’s image of a small star-forming region in the Rho Ophiuchi cloud complex.

“In just one year, the James Webb Space Telescope has transformed humanity’s view of the cosmos, peering into dust clouds and seeing light from faraway corners of the universe for the very first time. Every new image is a new discovery, empowering scientists around the globe to ask and answer questions they once could never dream of,” said NASA Administrator Bill Nelson. “Webb is an investment in American innovation but also a scientific feat made possible with NASA’s international partners that share a can-do spirit to push the boundaries of what is known to be possible. Thousands of engineers, scientists, and leaders poured their life’s passion into this mission, and their efforts will continue to improve our understanding of the origins of the universe – and our place in it.”

The new Webb image released today features the nearest star-forming region to us. Its proximity at 390 light-years allows for a highly detailed close-up, with no foreground stars in the intervening space.

“On its first anniversary, the James Webb Space Telescope has already delivered upon its promise to unfold the universe, gifting humanity with a breathtaking treasure trove of images and science that will last for decades,” said Nicola Fox, associate administrator of NASA’s Science Mission Directorate in Washington. “An engineering marvel built by the world’s leading scientists and engineers, Webb has given us a more intricate understanding of galaxies, stars, and the atmospheres of planets outside of our solar system than ever before, laying the groundwork for NASA to lead the world in a new era of scientific discovery and the search for habitable worlds.”

Webb’s image shows a region containing approximately 50 young stars, all of them similar in mass to the Sun, or smaller. The darkest areas are the densest, where thick dust cocoons still-forming protostars. Huge bipolar jets of molecular hydrogen, represented in red, dominate the image, appearing horizontally across the upper third and vertically on the right. These occur when a star first bursts through its natal envelope of cosmic dust, shooting out a pair of opposing jets into space like a newborn first stretching her arms out into the world. In contrast, the star S1 has carved out a glowing cave of dust in the lower half of the image. It is the only star in the image that is significantly more massive than the Sun.

“Webb’s image of Rho Ophiuchi allows us to witness a very brief period in the stellar lifecycle with new clarity. Our own Sun experienced a phase like this, long ago, and now we have the technology to see the beginning of another star’s story,” said Klaus Pontoppidan, who served as Webb project scientist at the Space Telescope Science Institute in Baltimore, Maryland, since before the telescope’s launch and through the first year of operations.

Some stars in the image display tell-tale shadows indicating protoplanetary disks – potential future planetary systems in the making. Discover more details in the image video tour, or explore yourself in the zoomable image.

A Full Year, Across the Full Sky

From its very first deep field image , unveiled by President Joe Biden, Vice President Kamala Harris, and Nelson live at the White House, Webb has delivered on its promise to show us more of the universe than ever before. However, Webb revealed much more than distant galaxies in the early universe.

“The breadth of science Webb is capable of exploring really becomes clear now, when we have a full year’s worth of data from targets across the sky,” said Eric Smith, associate director for research in the Astrophysics Division at NASA Headquarters and Webb program scientist. “Webb’s first year of science has not only taught us new things about our universe, but it has revealed the capabilities of the telescope to be greater than our expectations, meaning future discoveries will be even more amazing.” The global astronomy community has spent the past year excitedly poring over Webb’s initial public data and getting a feel for how to work with it.

Beyond the stunning infrared images, what really has scientists excited are Webb’s crisp spectra – the detailed information that can be gleaned from light by the telescope’s spectroscopic instruments. Webb’s spectra have confirmed the distances of some of the farthest galaxies ever observed, and have discovered the earliest, most distant supermassive black holes. They have identified the compositions of planet atmospheres (or lack thereof) with more detail than ever before, and have narrowed down what kinds of atmospheres may exist on rocky exoplanets for the first time. They also have revealed the chemical makeup of stellar nurseries and protoplanetary disks, detecting water, organic carbon-containing molecules, and more. Already, Webb observations have resulted in hundreds of scientific papers answering longstanding questions and raising new ones to address with Webb.

The breadth of Webb science is also apparent in its observations of the region of space we are most familiar with – our own solar system. Faint rings of gas giants appear out of the darkness, dotted by moons, while in the background Webb shows distant galaxies. By comparing detections of water and other molecules in our solar system with those found in the disks of other, much younger planetary systems, Webb is helping to build up clues about our own origins – how Earth became the ideal place for life as we know it.

"With a year of science under our belts, we know exactly how powerful this telescope is, and have delivered a year of spectacular data and discoveries,” said Webb senior project scientist Jane Rigby of the Goddard Space Flight Center. “We've selected an ambitious set of observations for year two that builds on everything we've learned so far. Webb's science mission is just getting started – there's so much more to come."

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 the Canadian Space Agency.
