The universe was born in darkness 13.8 billion years ago, and even after the first stars and galaxies blazed into existence a few hundred million years later, these too stayed dark. Their brilliant light, stretched by time and the expanding cosmos, dimmed into the infrared, rendering them — and other clues to our beginnings — inaccessible to every eye and instrument.

Until now. On Tuesday the James Webb Space Telescope, the most powerful space observatory yet built, offered a spectacular slide show of our previously invisible nascent cosmos. Ancient galaxies carpeting the sky like jewels on black velvet. Fledgling stars shining out from deep within cumulus clouds of interstellar dust. Hints of water vapor in the atmosphere of a remote exoplanet.

Their sum is both a new vision of the universe and a view of the universe as it once appeared new.

“That was always out there,” said Jane Rigby, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Md., and the telescope’s project scientist for operations. “We just had to build a telescope to go see what was there.”

The Webb telescope — NASA’s vaunted successor to the Hubble Space Telescope, 30 years and nearly $10 billion in the making — is equipped to gain access to this realm of cosmic history, study the first stars and galaxies and look for nearer, potentially habitable worlds. It is a collaboration among NASA, the European Space Agency and the Canadian Space Agency.

“We’re looking for the first things to come out of the Big Bang,” said John Mather, senior project scientist for the telescope.

President Biden offered a preview on Monday afternoon when he introduced what NASA officials and astronomers hailed as the deepest image yet taken of the cosmos, a mark that will probably be passed before the week is done as more data spews forth from NASA’s computers.

The image, of a distant star cluster called SMACS 0723, revealed the presence of still more-distant galaxies spilled across the sky. The light from those galaxies, magnified into visibility by the gravitational field of the cluster, originated more than 13 billion years ago.

To look outward into space is to peer into the past. Light travels at a constant 186,000 miles per second, or close to six trillion miles per year, through the vacuum of space. To observe a star 10 light-years away is to see it as it existed 10 years ago, when the light left its surface. The farther away a star or galaxy lies, the older it is, making every telescope a kind of time machine.

Astronomers theorize that the most distant, earliest stars may be unlike the stars we see today. The first stars were composed of pure hydrogen and helium left over from the Big Bang, and they could grow far more massive than the sun — and then collapse quickly and violently into supermassive black holes of the kind that now populate the centers of most galaxies.

The new pictures were rolled out during an hourlong ceremony at the Goddard Space Flight Center that was hosted by Michelle Thaller, the center’s assistant director for science communication, with video stops around the world. A few miles away at the Space Telescope Science Institute in Baltimore, an overflow crowd of astronomers whooped and hollered, oohed and aahed, as new images flashed on the screen — evidence that their telescope was working even better than hoped.

One infrared skyscape showed Stephan’s Quintet, five galaxies packed improbably tightly in the constellation Pegasus. Four are so closely engaged in a gravitational dance that they will eventually merge. Indeed, the image revealed a band of dust that was being heated up as two of the galaxies ripped stars from each other.

A view of the Southern Ring nebula, the remnants of an exploded star, revealed hints of complex carbon molecules known as polycyclic aromatic hydrocarbons, or PAHs, floating in its midst. Such molecules drift through space, settling in clouds that then give birth to new stars, planets, asteroids — and whatever life might subsequently sprout.

“Possibly, the formation of PAHs in these stars is a very important part of how life got started,” said Bruce Balick, an emeritus professor of astronomy at the University of Washington. “I’m gobsmacked.”

The most striking image was of the Carina nebula, a vast, swirling cloud of dust that is both a star nursery and home to some of the most luminous and explosive stars in the Milky Way. Seen in infrared, the nebula resembled a looming, eroded coastal cliff dotted with hundreds of stars that astronomers had never seen before.

“It took me awhile to figure out what to call out in this image,” Amber Straughn, deputy project scientist for the telescope, said as she pointed to a craggy structure.

Dr. Straughn added that she could not help thinking about the scale of the nebula, full of stars with planets of their own.

“We humans really are connected to the universe,” she said. “We’re made out of the same stuff in this landscape.”

From astronomers and at watch parties around the globe, there was uniform relief and praise.

“This event blew me away,” said Alan Dressler, an astronomer at the Carnegie Observatory who was instrumental in planning for the telescope 30 years ago. “Guess I’m not as jaded as I thought.”

He added: “The growth in our understanding of the universe will be as great as it was with the Hubble, and that is really saying something. We’re in for a great adventure.”

A ‘feeding frenzy’ in the sky

The pictures and other data released on Tuesday were selected by a small team of imaging experts and public outreach specialists for the images’ ability to show off the new telescope’s range and power — and to knock the public’s socks off.

These will be followed in the next six months by the results of studies in NASA’s Early Release Science Programs. Some results, including images of galaxies even more distant than the one shown by Mr. Biden on Monday, will be available later this week. On Thursday, all the data gathered during the testing of the telescope and its instruments will become available.

Now that the images are out, “there will be an astronomer feeding frenzy!” Garth Illingworth, a researcher at the University of California, Santa Cruz, and an initiator of the telescope program four decades ago, wrote in an email.

The Early Release Science Programs, intended to jump-start the Webb era, include studies of the solar system, galaxies, intergalactic space, massive black holes and the evolution of stars.

Jupiter and its myriad intriguing satellites, such as Europa, the target of an upcoming NASA mission, will be one focus. Two other studies will be devoted to exoplanets, including the Trappist-1 system, just 40 light-years away, where seven planets circle a dim red-dwarf star. Three of those planets are Earth-size rocks orbiting in the habitable zone, where water could exist on the surface.

Dreaming of the light unseen

Just as the Hubble Space Telescope defined astronomy for the last three decades, NASA expects Webb to define the field for a new generation of researchers who have been eagerly awaiting their own rendezvous with the cosmos.

It’s been a long time coming. What began as the Next Generation Space Telescope evolved into an infrared telescope capable of sensing the heat from the earliest stars and galaxies in the universe.

Because the cosmos is expanding, those earliest stars and galaxies are rushing away from Earth so fast that their light is shifted to longer, redder wavelengths, much as the sound from an ambulance’s siren shifts to a lower register as it speeds by. The light from the most distant and earliest galaxies and stars, once blue, is now infrared “heat” radiation, invisible to the eye. So too is the radiation from carbon, ozone and other molecules that are of keen interest to astrobiologists.

An early planning committee concluded that the telescope would need to be at least four meters in diameter (Hubble’s was just 2.4 meters across) and highly sensitive to infrared radiation, and it would cost $1 billion. NASA’s administrator, Dan Goldin, liked the idea but worried that a four-meter telescope would be too small to see the first stars, so he increased the size to eight meters.

Doubled in size, however, the telescope would no longer fit aboard any existing rocket. That meant the telescope’s mirror would have to be foldable, and it would have to unfurl itself in space. NASA eventually settled on a mirror 6.5 meters wide, with seven times the light-gathering power of Hubble’s.

Moreover, the telescope would have to be cooled to to minus 380 degrees Fahrenheit to prevent the telescope’s own heat from swamping the faint emanations from distant stars. (One instrument had to be even colder, minus 447 degrees Fahrenheit, just a few degrees above absolute zero.) This was accomplished by parking the telescope permanently behind a sunshade.

But all the challenges of developing and building the instrument remained. In 1990, NASA had sent Hubble into orbit with a misshapen mirror; still stinging from that embarrassment, the agency devised a long and expensive testing program for the new telescope. The price tag rose to $8 billion, and in 2011, Congress nearly canceled the project.

“Webb became the perfect storm,” Dr. Dressler recalled. “The more expensive it got, the more critical it was that it not fail, and that made it even more expensive.”

During one early test, the sun shield was torn. “When you work with a $10 billion telescope, there are no small problems,” said Thomas Zurbuchen, NASA’s associate administrator for science missions. “It’s hard to know what’s boldface and what is not.”

Christmas for Astronomers

The Webb telescope represents the combined effort of about 20,000 engineers, astronomers, technicians and bureaucrats, according to Bill Ochs, who has been the telescope’s project manager since 2011. It is now orbiting the sun at a spot called L2, where the combined gravitational fields of the sun and Earth create a stable resting spot. Its mirror, made of 18 gold-coated beryllium hexagons, suggests a sunflower floating on the blade of a giant shovel — the sunscreen that keeps the telescope cold and pointing ever outward from our star.

All of Webb’s troubles vanished on Christmas morning, when a flawless launch from French Guiana and lifted the telescope past hundreds of “single points of failure” and left it with twice as much maneuvering fuel as expected and the possibility of a 20-year career in science. The mirror also proved to be twice as good as expected at detecting the shortest wavelengths of light, increasing the telescope’s resolving power.

As the Goddard ceremony wrapped up on Tuesday, Dr. Zurbuchen and Dr. Mather took the stage to congratulate and praise the team that had worked together so long and well. Dr. Mather said that he had never worried that the telescope wouldn’t succeed. “Although maybe I should have,” he added.

Dr. Zurbuchen shot back: “I get paid to worry.”

How the Webb telescope compares with the Hubble.

The Webb telescope’s primary mirror is 6.5 meters in diameter, compared with Hubble’s, which is 2.4 meters, giving Webb about seven times as much light-gathering capability and thus the ability to see further into the past.

Another crucial difference is that Webb is equipped with cameras and other instruments sensitive to infrared, or “heat,” radiation. The expansion of the universe causes the light that would normally be in wavelengths that are visible to be shifted to longer infrared wavelengths that are normally invisible to human eyes.

On the other hand, the Hubble telescope is in low Earth orbit, where astronauts could visit and fix things that have broken or worn out, or install new, more powerful instruments on it. Those modifications extended its life years beyond the original estimates.

Get ready for an outpouring of Webb telescope science.

The pictures and other data released Tuesday were selected from a list of possible sources by a small team of imaging experts and public outreach specialists for their ability to show off the Webb telescope’s range and power, and to knock our socks off.

But other major scientific research is already underway, and in the months ahead, the results of a group of programs that NASA calls Early Release Science will be pouring into science journals and other repositories as fast as the astronomers can write them. Some of the results will be available on Thursday, including the data gathered while the telescope was being set up in space and images of distant galaxies that are even deeper than the one President Biden showed yesterday.

In the days ahead, “there will be an astronomer feeding frenzy!” said Garth Illingworth, an astronomer at the University of California, Santa Cruz and one of the initiators of the telescope almost 40 years ago.

Some 13 projects have been deemed Early Release Science Programs, chosen to jump start the Webb era. They range over five categories and include our solar system, galaxies and intergalactic space, massive black holes and the galaxies they live in, and the evolution of stars.

Included is a comprehensive look at Jupiter, our solar system’s largest planet, and its myriad and intriguing satellites like Europa, the target of an upcoming NASA mission. During a news conference on Monday, NASA scientists said the Webb had already looked at Jupiter, using the giant world to test if the telescope can take pictures of something that is extremely bright, compared with much more distant images.

Another study will be devoted to quasars and the supermassive black holes thought to fuel their fires.

“The science results are going to be rolling out from here on in,” said Jane Rigby, the operations project scientist for the telescope.

Two of these efforts with a high profile are devoted to exoplanets including the Trappist-1 system, just 40 light-years, or 235 trillion miles, away. There, seven planets circle a dim red dwarf star. Three are Earth-size rocks orbiting in the habitable zone, where water could exist on the surface.

“We’ll just have to wait for time to reveal the story,” said Knicole Colón, deputy project scientist for exoplanet science, when discussing the study of exoplanet atmospheres with the Webb.

I asked Thomas Zurbuchen, the associate administrator of NASA for science missions, if anything was clouding an otherwise celebratory day. “The biggest concern on our minds is just the micrometeorite environment,” he said, alluding to a small space-rock that dinged the telescope’s mirror in May. One potential solution under consideration, he was, has been to fly the telescope “backwards” through space, so any incoming dust would strike the backside of the mirror, not the front. He also stressed that a successful image rollout hasn’t washed away the memories of the overbudget mission’s less glamorous moments. “People told me, ‘After you see the first images, you will forget,’” he said. “We will never forget. We learned those lessons.”

In 2018, the James Webb Space Telescope, the beleaguered project to build an instrument that could gaze back to the earliest stars in the universe, appeared to be going off the rails. Again.

This is when Gregory Robinson was asked to take over as program director of Webb.

At the time, Mr. Robinson was the deputy associate administrator for programs at NASA, making him responsible for assessing the performance of more than 100 science missions.

He said no. “I was enjoying my job at the time,” Mr. Robinson recalled.

Eventually, Mr. Robinson relented. In March 2018, he stepped into the task of getting the telescope back on track and into space.

“He twisted both of my arms to take over Webb,” Mr. Robinson said.

His path to that role seemed an unlikely one.

At NASA, Mr. Robinson, 62, is a rarity: a Black man among the agency’s top-level managers.

“Certainly people seeing me in this role is an inspiration,” he said, “and also it’s acknowledging they can be there, too.”

When Mr. Robinson took over as program director, Webb’s schedule efficiency — a measure of how the pace of work compared with what had been planned — was down at about 55 percent, said Thomas Zurbuchen, NASA’s associate administrator for science. That, in large part, was the result of avoidable human error.

Dr. Zurbuchen said the Webb team had been full of smart, skilled people, who had become wary of raising criticism. He credited Mr. Robinson with turning things around. Within a few months, the efficiency was up to 95 percent, with better communications and managers more willing to share potential bad news.

“You needed somebody who could get the trust of the team and what we needed to figure out was what was wrong with the team,” Dr. Zurbuchen said. “The speed at which he turned this thing around was just astounding.”

The lonely work of picking Webb’s first five images.

On Tuesday morning, a new view of the Carina Nebula was made public alongside other new observations from the James Webb Space Telescope. But it made an earlier debut on another Tuesday morning — this one in June, when a small team clutching coffee cups gathered for one of many morning meetings to receive, process and repackage for public consumption what humanity’s latest and greatest set of eyes could see — after the team members had first signed nondisclosure agreements to ensure no early leaks.

This group’s task was a mix of on-the-fly science, public communication and brand management: Blow everyone’s mind, show policymakers what all those appropriations had paid for, and assure the rest of the scientific world that yes, some of the universe’s most elusive secrets might at long last be within reach.

The new telescope’s still-functioning predecessor, Hubble, had underscored the stakes. Hubble’s first-look images made it obvious that its mirror was flawed. But after successful repairs, scientists working on Hubble went on to crank out jaw-dropping, proto-viral photos of galaxies and nebulae like the “Pillars of Creation,” inspiring countless careers in the sciences. (Mine included: Before becoming a science journalist, I spent two years as a data analyst for Hubble, which is also run out of the Space Telescope Science Institute.)

But James Webb is another beast altogether, so distinctive and advanced in its capabilities that even veteran astronomers had little idea what to expect of the images it would yield. Much of that is because the Webb operates in infrared wavelengths.

Simply showing off this stuff would demand a distinct color palette and style. NASA wanted to start pushing out the first images within six weeks of the telescope’s coming online. And while staring into the abyss of the cosmic sublime for weeks on end would have its perks, the cone of silence around the project could also prove lonely.

In early June, for example, Klaus Pontoppidan, the astronomer leading this early release team, was the first human to download the new telescope’s full “deep field” view.

“I was sitting there, staring at it for two hours, and then desperately, desperately wanting to share it with someone,” he said. “But I couldn’t.”

In 2016, a committee convened to start choosing Webb’s very first demo targets. Ultimately, this process nominated around 70 possible targets.

Once the telescope had begun operating this winter, they whittled this list down to regions of the sky it could point to within the six-week time limit — plus a few held in reserve, to tease out in the next few months.

And then, finally, finally, the earliest results started trickling in through the bottleneck of Dr. Pontppidan’s computer in early June. From there, the team digitally combined raw frames into deeper, more polished exposures and then passed them on to image processors for color rendering.

“I just felt overwhelmed,” said Joe Depasquale, the lead image processor on the project, describing what it had felt like to see one scene of another star-forming nebula to come together — something with a more Carvaggio-esque, light-and-shadow effect that wasn’t included in the initial batch of releases. “This is going to blow people’s minds,” he said. (Confirmed.)

Will anything land as hard as the Apollo shots? Or the Hubble pics, plastered on science classroom walls and aped by everyone from Terrence Malick to the “Thor” movies? We’ll see. But for now, at least, the tap is open, and the universe is pouring in.

Marcia J. Rieke, 70, is the research group leader for the near-infrared camera, or NIRCam and a professor at the University of Arizona. She answered these questions for an interview published in March.

As principal investigator, you were responsible for designing and building the NIRCam, and now it’s your job to make sure it will work almost a million miles from Earth. How nerve-racking is that?

Being responsible for an instrument like NIRCam is like a repeated roller coaster ride. There’s the high point when you have the joy of seeing things work as you had hoped. There’s a low point, especially early on, when something breaks and the design needs to be modified. And then there’s waiting for the next ride, such as launch. Of course, the highest points will be when fantastic data are gathered, great papers are written about the discoveries and the younger people on the team get great jobs.

NIRCam has the potential to capture light emitted just after the Big Bang, nearly 14 billion years ago, that is only now reaching our galaxy. You have now seen some images. How did it feel?

We’ve gotten the first images and we’re super happy. The entire Webb team is ecstatic at how well the first steps of taking images and aligning the telescope are proceeding.

Do you think women bring a different set of perceptions to astronomy?

I have sensed over the years that different people come to conclusions by following different paths, and that is one reason it is good to have diversity.

What advice was most helpful in your career?

People need to do something they love doing. Find your passion and go for that.

Anything else?

In the scientific field right now, if you apply for time on a telescope or you write a proposal to get funding, the competition is really severe. I try to encourage young folks not to give up. Keep trying; you’ll get there.

It’s time for the hunt for life out there to really begin.

This month will mark a new chapter in the search for extraterrestrial life, when the most powerful space telescope yet built will start spying on planets that orbit other stars. Astronomers hope that the James Webb Space Telescope will reveal whether some of those planets harbor atmospheres that might support life.

Identifying an atmosphere in another solar system would be remarkable enough. But there is even a chance — albeit tiny — that one of these atmospheres will offer what is known as a biosignature: a signal of life itself.

“I think we will be able to find planets that we think are interesting — you know, good possibilities for life,” said Megan Mansfield, an astronomer at the University of Arizona. “But we won’t necessarily be able to just identify life immediately.”

The relatively small size of these exoplanets has made them extremely difficult to study, until now. The James Webb Space Telescope will change that, acting as a magnifying glass to let astronomers look more closely at these worlds.

The space telescope “is the first big space observatory to take the study of exoplanet atmospheres into account in its design,” Dr. Mansfield said.

A number of teams of astronomers are planning to look at the seven planets that orbit a star called Trappist-1. Earlier observations have suggested that three of the planets occupy the habitable zone.

It is possible that at the end of those efforts, Dr. Mansfield and her colleagues will discover an atmosphere around a Trappist-1 planet. But that result alone will not reveal the nature of the atmosphere. It might be rich in nitrogen and oxygen, like on Earth, or more akin to the toxic stew of carbon dioxide and sulfuric acid on Venus. Or it could be a mix that scientists have never seen before.

“We have no idea what these atmospheres are made of,” said Alexander Rathcke, an astronomer at the Technical University of Denmark. “We have ideas, simulations, and all this stuff, but we really have no idea. We have to go and look.”

What NASA shared from the Webb telescope today.

On Tuesday morning, NASA rolled out a series of images that showed the capabilities of the James Webb Space Telescope, the largest and most powerful space observatory ever built.

In an event at the Goddard Space Flight Center in Greenbelt, Md., officials and experts shared scenes the telescope recorded during its early work this spring, including an exploded star, a stellar nursery and an alien planet. At a parallel event in Baltimore at the Space Telescope Science Institute, employees who are managing the telescope and its science got to sit back and see the results of their hard work for the first time.

The four images revealed on Monday were:

On Monday, President Biden and NASA revealed a “deep field” image of galaxies from a time much closer to the start of the universe.

How the Webb telescope sees into the universe’s origins.

The Webb space telescope was built with some of the most advanced scientific instruments ever sent beyond Earth’s orbit. Astronomers believe the spacecraft will help them understand more about black holes, how stars are born and die and what lies within the atmospheres of planets orbiting other stars; perhaps, it will even give us a glimpse of an era close to the Big Bang.

Why does seeing further help scientists see billion years into the past?

Remember the speed of light? A constant pace of more than 186,000 miles per second, or close to six trillion miles per year, through the vacuum of space.

That makes a light-year — the distance light travels in one year — a handy measuring stick for cosmic distances.

It also explains why looking out into the universe is looking into the past.

If a star is 10 light-years away, that means its light has taken 10 years to reach us: We are observing the star as it existed 10 years ago. (The light from the sun takes eight minutes to reach us on Earth.)

For the most distant objects that the Webb can detect, those particles of light have traveled some 13 billion light-years, traveling across space for 13 billion years. The light in the Webb “deep field” image released on Monday is a snapshot of a part of the universe when it was less than a billion years old.

What could learning more about the period closer to the Big Bang teach astronomers?

When did the first stars light up? When did the first galaxies coalesce out of clouds of gas? How different were the first stars and galaxies from the ones that fill the universe today?

No one really knows. It’s a missing chapter in the history of the universe. We know the universe started in an instant from the Big Bang. That explosion left a background hiss of microwave noise that was discovered in 1964, and it has been studied in detail in the decades since. The universe cooled down, matter began to clump and the first stars are thought to have formed about 100 million years after the Big Bang.

The early stars must have been different because the Big Bang created only hydrogen and helium with a smidgen of lithium and beryllium. None of the heavier elements — carbon, silicon, iron and the rest of the periodic table — existed. Some astrophysicists believe that many of the first stars, devoid of heavier elements, were huge, burned bright and died young in supernova explosions to disperse materials that could later form planets and, eventually, living creatures like us.

The Webb is the first telescope that might be able to spot and analyze those early stars.

Why do the Webb’s tools help advance this work?

The two main differences between Webb and Hubble are the size of their mirrors — bigger mirrors gather more light — and the wavelengths of light they observe. Hubble focused on visible and ultraviolet wavelengths, offering unparalleled new views of much of the universe.

But for the early universe, the infrared part of the spectrum becomes key. That is because of the Doppler effect. When a police car speeds by, the pitch of the siren is higher when the car is approaching and drops lower when it is speeding away. Essentially the same thing occurs with light. Objects speeding toward us appear bluer, and those moving away become redder because the receding motion stretches out of the wavelengths of the light particle. For the most distant objects, like the early stars and galaxies, much of the light has been shifted all the way to the infrared.

Infrared observations are essentially impossible from telescopes on Earth. The atmosphere blocks out those wavelengths.

Infrared observations can also be easily distorted by heat radiation. That is why Webb was placed a million miles from Earth and shaded by a huge sun shield. One of the instruments, the Mid-Infrared Instrument, or MIRI, has to be cooled to minus 447 degrees Fahrenheit to work properly.

The Carina nebula is a turbulent cloud of gas, dust about 7,600 light-years from here, a birthplace and graveyard for some of the Milky Way’s hottest and most massive stars.

The nebula is home to some of the most luminous and potentially explosive stars in the galaxy. Among them in particular is Eta Carinae, a double star system of which the stormy, primary member is as massive as 200 suns and is five million times the luminosity of the star that fills your daytime sky. Over the years, the primary star has emitted periodic eruptions as it has aged and quaked. At least 20 solar masses of gas and dust have been expelled into the nebula, which have obscured Eta Carinae itself, as well as the other denizens of the nebula.

Infrared radiation can penetrate dust, so astronomers hope to find out more about the stars being formed in the roiling nebula and about Eta Carinae itself, which seems to be on the road to exploding as a supernova one of these days or centuries.

“It took me awhile to figure out what to call out in this image,” said Amber Straughn, deputy project scientist for the telescope.

Dr. Straughn added that she could not help thinking about the sense of scale in the Webb’s image of the nebula, filled as it is with individual stars with planets of their own.

“We humans really are connected to the universe,” she said. “We’re made out of the same stuff in this landscape.”

One nice feature of being part of an audience of astronomers is you can use their oohs and aahs to vet what’s actually groundbreaking — in this case, the mid-infrared view of this galactic scene, which illuminates everything including tail-like strips of stars and dusty, glowing clouds, sparked a major reaction.

First look: Stephan’s Quintet

Stephan’s Quintet is a snippet of the night sky that looks unreal — five galaxies that appear to be almost touching each other. In 1877, Édouard Stephan, an astronomer at the Marseille Observatory in France, was first to spot the group, located in the constellation Pegasus.

The visual juxtaposition is, in part, an illusion. One of the galaxies, NGC 7320, is actually much closer to us, about 40 million light-years from Earth, but along the line of sight with the others. The other four galaxies, however, are all about 300 million light-years away, part of what astronomers call a compact group of galaxies.

“They’re locked in a close interaction, a sort of cosmic dance driven by the gravitational force,” said Giovanna Giardino, an astronomer at the European Space Agency.

The Webb image provides a clearer view at the tails and loops of gas and stars in the four distant galaxies as well as bright emissions of X-rays from diffuse hot gas. “It really shows the type of interaction that drives the evolution of galaxies,” Dr. Giardino said.

Astronomers are still working to understand how several galaxies can end up that close together.

Two of the galaxies are in the process of merging, and the infrared images show “gas and dust, which is being heated up in the collision between those galaxies,” said Mark McCaughrean, senior adviser for science and exploration for the European Space Agency. “And that’s a place where new stars are being born today.”

A variation of the image, showing the mid-infrared light without the shorter near-infrared wavelengths, showed mainly gas and dust. One of the galaxies includes a particularly bright spot, from material becoming superhot as it falls into a gargantuan black hole at the center of the galaxy. The luminosity of the gases is 40 billion times that of our sun.

“It’s really, really bright,” Dr. Giardino said.

It took combing almost 1,000 individual images and 150 megapixels to adequately capture a gaggle of five interacting galaxies called Stephan’s Quintet, says Dr. David Law. Zooming in, he shows the two galaxies on the lower right ripping stars and gas away from each other. “Even as galaxies are destroyed, Webb shows the birth of new stars.”

First look: Southern Ring Nebula

The image shows the Southern Ring Nebula, a dying star, expelling a colorful gas cloud that will eventually expand and fade away into the space between stars.

Webb’s view of the Southern Ring Nebula, imaged in mid-infrared wavelengths, adds new wrinkles to a cycle of death and rebirth linked to everything including mysterious carbon molecules that permeate interstellar space and the eventual fate of our own solar system.

The scene in this image began when a star shuddered and died, launching its own atmosphere into space like an expanding soap bubble. The only part of the star left behind was a scalding-hot core known as a white dwarf, in the center of the image.

Most stars in the universe, including our sun, will end their lives in nebulae like this one. That colorful gas cloud will eventually expand and fade away into the space between stars. But the Webb telescope’s infrared view shows light emitted by a set of complex carbon molecules that are born from the same process: polycyclic aromatic hydrocarbons, or PAHs.

Those same carbon molecules drift through space, settling in clouds that then give birth to new stars, planets, asteroids — and whatever life might subsequently sprout. “Possibly, the formation of PAHs in these stars is a very important part of how life got started,” said Bruce Balick, an emeritus professor of astronomy at the University of Washington.

Compared with previous studies of the Southern Ring Nebula from the Hubble Space Telescope, the new image shows more of its outskirts: the first material that was launched from the star to spread away. It also reveals glowing grains of carbon, and a better view of a companion star huddled at the center of the nebula.

“I’m gobsmacked,” Dr. Balick said, after seeing the new image for the first time.

Just as Hubble did in the early 1990s when its first pictures started rolling in, Dr. Balick expects Webb will have its own transformative effect on our understanding of star-forming nebulae.

“We all realized we could just take most of the work that we had already done and rip it up and start over,” he said.

Setting stunning space pictures aside, the bulk of the James Webb Space Telescope’s most profound scientific work — the where-do-we-come-from, are-we-alone stuff — will probably involve little squiggles on graphs of a planet orbiting a distant star.

Many astronomers want to sniff out which molecules swirl and waft through the atmosphere of planets around other stars. But they face at least two major hurdles. First, attempting such a measurement strains even the best contemporary technology. And second, many of the planets we have attempted to study so far seem to be blanketed in layers of clouds, which block our gaze.

Enter Webb’s glimpse of WASP-96b, a gas giant planet orbiting a sun-like star 1,120 light-years from Earth. Its mass is more than that of Saturn but only about half as much as Jupiter’s. Blissfully, for whatever reason, ground-based observations proved in 2018 that this particular planet has clear skies, a boon to astronomers hoping to peer in.

The new Webb measurements show evidence of water vapor, hazes and some previously unseen clouds, too.

“This is great to see,” said Jonathan Fortney, an astronomer at the University of California, Santa Cruz. He added that the traces of clouds where none were expected is a surprise. “I don’t know what to say!”

Seeing all this required careful timing. From our solar system’s perspective, WASP-96b sweeps across the surface of its star every three and half days, blotting out a small fraction of starlight during that transit passage. During that time, as the Webb watched, an even smaller number of light rays passed through the ring of atmosphere around the planet, providing the spectral fingerprints of floating molecules.

Over time, measurements like these should help us understand the birth of gas giant planets like WASP-96b — and our own Saturn and Jupiter, as well — during the formation of stars systems, clock climate patterns sweeping around them and, just maybe, for smaller worlds, enable searches for signs of life.

Unless you keep your brand-new car in the garage all of the time, scratches and dents are inevitable.

Still, the first blemish can be painful to see.

For a spacecraft like the James Webb Space Telescope, it was inevitable that pieces of cosmic dust would hit its mirrors. Still, it was an unwelcome surprise for NASA officials to find that one of the telescope’s mirrors had been damaged by a micrometeoroid strike in late May and that the hit was larger than had been expected.

The little wallop noticeably distorted the observations, and the science gathering had not even started yet.

But NASA officials said the distortion is barely noticeable, and the performance of Webb still exceeds all of its requirements. Engineers also tweaked the position of the damaged mirror to cancel out part of the distortion.

“It wasn’t really a surprise,” said Gregory Robinson, the program director for Webb.

Before the incident was reported, four smaller micrometeoroids had already hit the telescope.

When Webb passes near known meteor showers, the telescope will turn its mirrors away to minimize their chances of being harmed. But the hit in May was not part of a meteor shower, just bad luck. It did not change operations of the telescope or the schedule for releasing images this week.

And such strikes have their own scientific value: The gradual accumulation of damage will give scientists better knowledge about the distribution of dust where the space telescope orbits, a location a million miles from Earth.

Who was James Webb, anyway?

Image

In 2002, Sean O’Keefe, then the NASA administrator, announced that the agency’s next telescope would be named for James Webb, who led NASA during the 1960s, when it was gearing up to land people on the moon. He was a staunch champion of space science.

Some astronomers were disappointed that it would not be named for an astronomer, while others objected on more serious grounds, namely that Mr. Webb bore some responsibility for an event during the Truman administration known as the Lavender Scare that resulted in the purging of gay and lesbian employees from the State Department. At the time, Mr. Webb had been the under secretary of state.

That issue gained prominence a year ago when four astronomers — Lucianne Walkowicz of the JustSpace Alliance and Adler Planetarium in Chicago, Chanda Prescod-Weinstein of the University of New Hampshire, Brian Nord of the Fermi National Accelerator Laboratory and the University of Chicago and Sarah Tuttle of the University of Washington — published an op-ed in Scientific American, “The James Webb Space Telescope Needs to Be Renamed.”

NASA said it would investigate the claims and publish a report. Subsequently, last September, Bill Nelson, the current NASA administrator and a former Florida senator, announced that he saw no need to change the name. No report was ever released, infuriating the critics.

In March after the telescope launched, Nature magazine reported on the basis of FOIA requests that NASA had taken the allegations seriously enough that Paul Hertz, then NASA’s director of astrophysics, had written outside astronomers asking if he should change the telescope’s name. The answer was no, but he did not talk to any L.G.B.T.Q. astronomers.

The magazine also reported records from the case of Clifford Norton. He had been fired from NASA in 1963 — during Mr. Webb’s tenure — for being gay, and the archival materials alluded to “a custom in the agency” of firing people for homosexual activity. Mr. Norton appealed and won a landmark case against such discrimination in 1969.

In November of 2021, NASA’s Astrophysics Advisory Committee asked the agency for fuller report.

Mr. O’Keefe, the former administrator, defended his choice in an email.

“Arguably, were it not for James Webb’s determination to fulfill the most audacious vision of his time, our capacity to explore today would be starkly different,” Mr. O’Keefe said.

But that was not enough for the critics. “If he’s not responsible for the bad stuff that happened while he was in charge, why is he responsible for the good stuff?” Dr. Prescod-Weinstein said. “It seems there’s a bit of double-think happening here, where people assign him responsibility for the things they like about his legacy and pretend that he’s only responsible for the things they like.”

“Our telescopes, if they are going to be named after people, should be named after people who inspire us to be our better selves,” Dr. Prescod-Weinstein added.

After the first images were revealed of the Webb telescope on Tuesday, a NASA spokeswoman said during a news conference that the agency’s historians are looking further into Mr. Webb’s history.
