the telescope will photograph distant galaxies

The telescope, known as one of "humanity's greatest scientific instruments" and launched in April 1990, can view distant galaxies at an extremely high resolution. Webb has a primary mirror that is 21.4 feet (6.5 meters) across that measures the light from distant galaxies. (In comparison, the Hubble Space Telescope's mirror is 7.8 feet [2.4 meters]). It's made of 18 hexagonal beryllium sections that unfold after launch, then coordinate to act like one whopping primary mirror. Story continues below advertisement.

The James Webb Space Telescope team has released the first science-quality images from the new telescope. In them are the oldest galaxies ever seen by human eyes, evidence of water on a planet 1,000 light-years away and incredible details showing the birth and death of stars.

With help from a galactic gravitational anomaly, the telescope could see the molecules from more than 12 billion light-years molecules in question are known as polycyclic aromatic hydrocarbons PAHs, and here on Earth, they’re usually present in smoke and smog from burning wood, coal, oil, gas and other materials. They’ve been detected throughout the universe, and were often thought of as the smoke to the fire of star formation. But the new Webb observations suggest that might not be the case.“These big molecules are actually pretty common in space,” said Justin Spilker, lead author of the study. “Astronomers used to think they were a good sign that new stars were forming. Anywhere you saw these molecules, baby stars were also right there blazing away. Thanks to the high-definition images from Webb, we found a lot of regions with smoke but no star formation, and others with new stars forming but no smoke.”The telescope spotted PAHs much farther back in space and time than ever before – in a galaxy located more than 12 billion light-years away. That means we’re seeing it as it existed just billion years after the Big Bang, marking the first time these molecules have been detected in the early galaxy itself was first discovered in 2013, but it took the extraordinary eyesight of the James Webb Space Telescope before the molecules could be picked up. Even then, it needed a boost from a cosmic magnifying glass. A diagram illustrating how gravitational lensing works to magnify distant galaxiesS. Doyle/J. Spilker Massive objects like galaxies can distort the very fabric of spacetime, which in turn can bend the path of passing light. This can magnify a distant object that would be otherwise invisible to us and make it detectable, through a phenomenon called gravitational this case, the target galaxy was magnified by the gravity of another galaxy much closer to us, which just so happens to be perfectly aligned from our perspective. This creates an effect known as an Einstein ring, where the background galaxy is stretched into a ring shape surrounding the foreground galaxy. In doing so, the telescope could pick up the “smoke signals” from farther away than ever may be the first such detection, but the researchers say it likely won’t be the last. Future observations could help astronomers unravel the connection between these molecules and star formation.“These are early days for the Webb Telescope, so astronomers are excited to see all the new things it can do for us,” said Spilker. “Maybe we’ll even be able to find galaxies that are so young that complex molecules like these haven’t had time to form in the vacuum of space yet, so galaxies are all fire and no smoke. The only way to know for sure is to look at more galaxies, hopefully even further away than this one.”The research was published in the journal Texas A&M A telescope image of distant galaxies, showing thousands of bright stars and galaxies on a black background.

Image credit NASA, ESA, CSA, Swinburne University of Technology, University of Pittsburgh, STScI The James Webb Space Telescope JWST has identified one of the most distant galaxies ever seen — an ancient, nearly invisible star cluster so remote that its light is the faintest scientists have ever JD1, the galaxy — whose light traveled for roughly billion years to reach us — was born just a few million years after the Big Bang. Back then, the cosmos was shrouded in a pitch-black fog that not even light could pass through; galaxies like this one were vital in burning the gloom from within the Sculptor constellation in the southern sky, JD1's light left its source when the universe was just 4% of its current age. The light crossed dissipating gas clouds and boundless space before passing through the galaxy cluster Abell 2744, whose space-time-warping gravitational pull acted as a giant magnifying lens to steer the ancient galaxy into focus for the JWST. The researchers who discovered the dim, distant galaxy published their findings May 17 in the journal Can the James Webb Space Telescope really see the past?"Before the Webb telescope switched on, just a year ago, we could not even dream of confirming such a faint galaxy," Tommaso Treu, a physics and astronomy professor at the University of California, Los Angeles UCLA, said in a statement. "The combination of JWST and the magnifying power of gravitational lensing is a revolution. We are rewriting the book on how galaxies formed and evolved in the immediate aftermath of the Big Bang."In the first hundreds of millions of years after the Big Bang, the expanding universe cooled enough to allow protons to bind with electrons, creating a vast shroud of light-blocking hydrogen gas that blanketed the cosmos in darkness. From the eddies of this cosmic sea-foam, the first stars and galaxies clotted, beaming out ultraviolet light that reionized the hydrogen fog, breaking it down into protons and electrons to render the universe transparent have observed evidence for reionization in many places the dimming of brightly flaring quasars ultrabright objects powered by supermassive black holes; the scattering of light from electrons in the cosmic microwave background; and the infrequent, dim light given off by hydrogen clouds. Yet because the first galaxies used so much of their light to dissipate the stifling hydrogen mist, what they actually looked like has long remained a mystery to astronomers. "Most of the galaxies found with JWST so far are bright galaxies that are rare and not thought to be particularly representative of the young galaxies that populated the early universe," first author Guido Roberts-Borsani, an astronomer at UCLA, said in the statement. "As such, while important, they are not thought to be the main agents that burned through all of that hydrogen fog."Ultra-faint galaxies such as JD1, on the other hand, are far more numerous, which is why we believe they are more representative of the galaxies that conducted the reionization process, allowing ultraviolet light to travel unimpeded through space and time," Roberts-Borsani discover JD1's first stirrings from beneath its hydrogen cocoon, the researchers used the JWST to study the galaxy's gravitationally lensed image in the infrared and near-infrared spectra of light. This enabled them to detect JD1's age, distance from Earth and elemental composition, as well as estimate how many stars it had formed. The team also made out a trace of the galaxy's structure a compact glob built from three main spurs of star-birthing gas and dust. The astronomers' next task is to use their technique to unveil even more of these first galaxies, revealing how they worked in unison to bathe the universe in light.

Tags Most Popular It has been an exciting week with the release of breathtaking photos of our Universe by the James Webb Space Telescope JWST. Images such as the one below give us a chance to see faint distant galaxies as they were more than 13 billion years ago. The SMACS 0723 deep field image was taken with only a exposure. Faint galaxies in this image emitted this light more than 13 billion years ago. NASA, ESA, CSA, and STScI It’s the perfect time to step back and appreciate our first-class ticket to the depths of the Universe and how these images allow us to look back in time. These images also raise interesting points about how the expansion of the Universe factors into the way we calculate distances at a cosmological scale. Modern time travel Looking back in time might sound like a strange concept, but it’s what space researchers do every single day. Our Universe is bound by the rules of physics, with one of the best-known “rules” being the speed of light. And when we talk about “light”, we’re actually referring to all the wavelengths across the electromagnetic spectrum, which travel at around a whooping 300,000 kilometres per second. Light travels so fast that in our everyday lives it appears to be instantaneous. Even at these break-neck speeds, it still takes some time to travel anywhere across the cosmos. When you look at the Moon, you actually see it as it was seconds ago. It’s only a tiny peek back in time, but it’s still the past. It’s the same with sunlight, except the photons light particles emitted from the Sun’s surface travel just over eight minutes before they finally reach Earth. Our galaxy, the Milky Way, spans 100,000+ light-years. And the beautiful newborn stars seen in JWST’s Carina Nebula image are 7,500 light-years away. In other words, this nebula as pictured is from a time roughly 2,000 years earlier than when the first ever writing is thought to have been invented in ancient Mesopotamia. The Carina Nebula is a birthplace for stars. NASA, ESA, CSA, and STScI Anytime we look away from the Earth, we’re looking back in time to how things once were. This is a superpower for astronomers because we can use light, as observed throughout time, to try to puzzle together the mystery of our universe. What makes JWST spectacular Space-based telescopes let us see certain ranges of light that are unable to pass through Earth’s dense atmosphere. The Hubble space telescope was designed and optimised to use both ultraviolet UV and visible parts of the electromagnetic spectrum. The JWST was designed to use a broad range of infrared light. And this is a key reason the JWST can see further back in time than Hubble. The electromagnetic spectrum with Hubble and JWST’s ranges. Hubble is optimised to see shorter wavelengths. These two telescopes complement each other, giving us a fuller picture of the universe. NASA, J. Olmsted STScI Galaxies emit a range of wavelengths on the electromagnetic spectrum, from gamma rays to radio waves, and everything in between. All of these give us important information about the different physics occurring in a galaxy. When galaxies are near us, their light hasn’t changed that much since being emitted, and we can probe a vast range of these wavelengths to understand what’s happening inside them. But when galaxies are extremely far away, we no longer have that luxury. The light from the most distant galaxies, as we see it now, has been stretched to longer and redder wavelengths due to the expansion of the universe. This means some of the light that would have been visible to our eyes when it was first emitted has since lost energy as the universe expanded. It’s now in a completely different region of the electromagnetic spectrum. This is a phenomenon called “cosmological redshift”. And this is where the JWST really shines. The broad range of infrared wavelengths detectable by JWST allow it to see galaxies Hubble never could. Combine this capability with the JWST’s enormous mirror and superb pixel resolution, and you have the most powerful time machine in the known universe. Read more Two experts break down the James Webb Space Telescope's first images, and explain what we've already learnt Light age does not equal distance Using the JWST, we will be able to capture extremely distant galaxies as they were only 100 million years after the Big Bang – which happened around billion years ago. So we will be able to see light from billion years ago. What’s about to hurt your brain, however, is that those galaxies are not billion light-years away. The actual distance to those galaxies today would be ~46 billion light-years. This discrepancy is all thanks to the expanding universe, and makes working on a very large scale tricky. The universe is expending due to something called “dark energy”. It’s thought to be a universal constant, acting equally in all areas of space-time the fabric of our universe. And the more the universe expands, the greater the effect dark energy has on its expansion. This is why even though the universe is billion years old, it’s actually about 93 billion light-years across. We can’t see the effect of dark energy on a galactic scale within the Milky Way but we can see it over much greater cosmological distances. Sit back and enjoy We live in a remarkable time of technology. Just 100 years ago, we didn’t know there were galaxies outside our own. Now we estimate there are trillions, and we are spoilt for choice. For the foreseeable future, the JWST will be taking us on a journey through space and time each and every week.

NASA's James Webb Space Telescope has shared a mesmerising and never-before-seen picture showing more than 45,000 galaxies in one frame. The picture was of a portion of the sky known as GOODS-Sout. James Webb Space Telescope captured the image as part of the JWST Advanced Deep Extragalactic Survey per the space agency, around 32 days of the telescope time will be devoted to the JADES programme to uncover and characterise distant and faint galaxies as astronomers make efforts to understand how the first stars and galaxies were formed. Although the data is still pouring in, hundreds of galaxies have already been discovered that existed when the universe had not completed 600 million years. Galaxies, which were sparkling along with a number of young, hot stars, have also been identified by the of the JADES programme and professor at the University of Arizona in Tucson Marcia Rieke said, "With JADES, we want to answer a lot of questions, like How did the earliest galaxies assemble themselves? How fast did they form stars? Why do some galaxies stop forming stars?"The part of the sky was previously observed by the Hubble telescope. You're looking at 45,000+ galaxies. This image was taken as part of the JWST Advanced Deep Extragalactic Survey JADES — a massive science program that’s revolutionizing what we know about galaxies in the early universe Here are the highlights ⬇️ — NASA Webb Telescope NASAWebb June 5, 2023 × Investigation into galaxies that existed 500 to 850 million years after the big bang University of Texas' Ryan Endsley headed the investigation into galaxies which existed 500 to 850 million years after the big bang occurred. "For hundreds of millions of years after the big bang, the universe was filled with a gaseous fog that made it opaque to energetic light. By one billion years after the big bang, the fog had cleared and the universe became transparent, a process known as reionisation. Scientists have debated whether active, supermassive black holes or galaxies full of hot, young stars were the primary cause of reionisation," the space agency explained. The researchers found evidence of young galaxies going through rapid star formation interspersed with short periods where fewer stars formed. WATCH NASA mission to Saturn's moon Titan may unravel secrets behind origin of life “Almost every single galaxy that we are finding shows these unusually strong emission line signatures indicating intense recent star formation. These early galaxies were very good at creating hot, massive stars,” stated Ryan Endsley of the University of Texas, who headed the investigation.“Previously, the earliest galaxies we could see just looked like little smudges. And yet those smudges represent millions or even billions of stars at the beginning of the universe. Now, we can see that some of them are actually extended objects with visible structures. We can see groupings of stars being born only a few hundred million years after the beginning of time,” stated Kevin Hainline of the University of Arizona, in a statement.

The study is part of an international collaboration called the JWST Advanced Deep Extragalactic Survey JADES, which gathered a month's worth of observations from two tiny patches in the sky One in the Ursa Minor constellation and another in the direction of the Fornax cluster. Within this region were over 700 newly discovered young galaxies that reveal with the cosmos looked like in its earliest"If you took the whole universe and shrunk it down to a two hour movie, you are seeing the first five minutes of the movie," Kevin Hainline, an assistant research professor at the Steward Observatory in Arizona and a lead author of the new study, said while announcing the discovery on Monday June 5 at the 242nd meeting of the American Astronomical Society being held in Albuquerque and online. "These are the galaxies that are starting the process of making the elements and the complexity that we see in the world around us today."These new findings shed light on how the first galaxies and stars formed, creating the rich catalog of elements observed in the universe James Webb Space Telescope JWST — A complete guideIn those five minutes alone, which marks the universe to be between 370 million and 650 million years old, Hainline's and his colleagues studying Webb's data found 717 young galaxies — which turns out to be higher than previous predictions — with all of them already spanning thousands of light-years, sporting complex structures, and birthing stars in multiple clusters. "Previously, the earliest galaxies we could see just looked like little smudges. And yet those smudges represent millions or even billions of stars at the beginning of the universe," Hainline said in a statement. "Now, we can see that some of them are actually extended objects with visible structure." Together, the two regions used in this study are referred to as GOODS-South, an acronym for The Great Observatories Origins Deep Survey, and have been extensively studied by nearly all major space telescopes, including Hubble, the Chandra X-Ray Observatory and NASA's now-retired this previous scrutiny, 93% of the newfound galaxies that Webb spotted during JADES had never been seen image of the GOODS-South field, captured by JWST's NIRCam Near-Infrared Camera, shows compass arrows, scale bar, and color key for reference.

"Now we are really probing down to more normal, everyday galaxies in a turbulent young universe."Precisely how that chaotic, very dusty environment cleared up to become the transparent cosmos we see today has long been debated. A leading theory is that this phase of evolution of the universe, called the Epoch of Reionization, occurred some 400,000 years after the Big Bang, when the first generation of stars — thought to be 30 to 300 times our sun's mass and millions of times more bright — formed and flooded the opaque universe with its first light. That ultraviolet starlight reionized the universe by splitting its abundant hydrogen atoms into protons and electrons, a process that lasted until one billion years after the Big Bang. However, few astronomers say outflows from supermassive black holes, similar to the one that resides in the heart of our Milky Way, could have triggered the escape of ultraviolet radiation from galaxies and thus played a more important role in cosmic evolution than previously a second team from the JADES program that has been studying galaxies that existed between 500 to 850 million years after the Big Bang, or between five to eight minutes of the two-hour movie describing the universe, thinks it has an answer to the long-standing question."In this next scene of the universe, we are starting to actually see the impact of galaxy formation on the composition of the large scale universe," Ryan Endsley, a postdoctoral researcher at the University of Texas who led the second study, said at the news conference on Monday. "Galaxies in the very early universe were just far more chaotic in general in how they formed stars."Endsley's team studied the signs of star formation in those very early galaxies, which provided insight into how starlight ionized the gas within those galaxies. The team found that one in six galaxies at the time showed extreme line emissions in the galaxy's spectra, a feature that atoms ionized by starlight radiate when they have cooled down and combined with other emission lines are evidence that early galaxies were actively birthing stars, which then pumped "torrents of ultraviolet photons" into their respective galaxies. This way, the universe's early stars became the main drivers of cosmic reionization, Endsley said."These extreme emission lines are actually relatively common in the very early universe," he said during his presentation. "Almost every single galaxy that we are finding shows these unusually strong emission line signatures indicating intense recent star formation," he added in the statement. "These early galaxies were very good at creating hot, massive stars."From the same emission lines, Endsley's team also inferred that galaxies in the early universe birthed stars in short bursts followed by quiescent periods."All of a sudden you would have tens of suns worth of solar masses being assembled all at once in these early galaxies," Endsley told reporters at the news briefing on Monday. "That's really important for our understanding of how reionization happened because these hot massive stars were very efficient producers of these ultraviolet photons that we needed in order to ionize all the hydrogen in the early universe."
