CNN — Astronomers have detected the most distant known organic molecules in the universe using the James Webb Space Telescope. It’s the first time Webb has detected complex molecules in the distant universe. The complex molecules were found in a galaxy known as SPT0418-47, located more than 12 billion light-years away. The discovery sheds light on the chemical interactions that occurred within the earliest galaxies in the universe and how they relate to star formation. On Earth, the molecules, called polycyclic aromatic hydrocarbons, can be found in smoke, soot, smog, engine exhaust and forest fires. The base of the organic molecules is carbon, considered to be one of the building blocks of life because it’s a key element in amino acids, which form proteins. A study detailing the findings was published Monday in the journal Nature. The light from the dusty galaxy began traveling across the cosmos when the universe was less than billion years old, just 10% of its current age of billion years. The galaxy was first spotted in 2013 by the National Science Foundation’s South Pole Telescope. Other observatories, such as the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array in Chile, have observed it since. But the Webb telescope’s infrared capabilities, which can see light invisible to the human eye and peer through cosmic dust, was able to capture new details about the galaxy. And the space observatory received a helping hand from a phenomenon called gravitational lensing. “This magnification happens when two galaxies are almost perfectly aligned from the Earth’s point of view, and light from the background galaxy is warped and magnified by the foreground galaxy into a ring-like shape, known as an Einstein ring,†said study coauthor Joaquin Vieira, professor of astronomy and physics at the University of Illinois Urbana-Champaign, in a statement. Gravitational lensing was originally predicted in Albert Einstein’s theory of relativity. “By combining Webb’s amazing capabilities with a natural ‘cosmic magnifying glass,’ we were able to see even more detail than we otherwise could,†said lead study author Justin Spilker, an assistant professor of physics and astronomy at Texas A&M University, in a statement. “That level of magnification is actually what made us interested in looking at this galaxy with Webb in the first place, because it really lets us see all the rich details of what makes up a galaxy in the early universe that we could never do otherwise,†said Spilker, who is also a member of Texas A&M’s George P. and Cynthia Woods Mitchell Institute for Fundamental Physics and Astronomy. Astronomers spotted the signature of the organic molecules during a careful analysis of Webb’s data. The molecules are common in space. Here on Earth, they are part of cancer-causing hydrocarbon emissions that contribute to the planet’s atmospheric pollution. Previously, astronomers thought polycyclic aromatic hydrocarbons were a sign of star formation because they have observed the large molecules near bright young stars. But Webb’s data revealed the presence of these molecules may not have been an indicator of star birth in the early days of the universe. “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,†Spilker said. The unexpected finding is helping astronomers piece together answers to some of the lingering questions about the beginning of the universe. “Discoveries like this are precisely what Webb was built to do understand the earliest stages of the universe in new and exciting ways,†said study coauthor Kedar Phadke, a doctoral student of astronomy at the University of Illinois Urbana-Champaign, in a statement. “It’s amazing that we can identify molecules billions of light-years away that we’re familiar with here on Earth, even if they show up in ways we don’t like, like smog and smoke. It’s also a powerful statement about the amazing capabilities of Webb that we’ve never had The researchers are looking forward to flexing Webb’s capabilities more in the future as they search for even more distant galaxies. “Now that we’ve shown this is possible for the first time, we’re looking forward to trying to understand whether it’s really true that where there’s smoke, there’s fire,†Spilker said. “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
Nasa’s new space telescope has gazed into the distant universe and shown perfect vision a spiky image of a faraway star photobombed by thousands of ancient image released on Wednesday from the James Webb Space telescope was a test shot – not an official science observation – to see how its 18 hexagonal mirrors worked together for a single coordinated image taken 1m miles km away from Earth. Officials said it worked better than month, Nasa looked at a much closer star with 18 separate images from its mirror segments. That star, known as HD 84406, is 258 light years away in the constellation Ursa said they were giddy as they watched the latest test photos arrive. Nasa’s test image was aimed at a star 100 times fainter than the human eye can see. This star – called 2MASS J17554042+6551277 – is 2,000 light years away from HD 84406. A light year is nearly 6tn miles km.The shape of Webb’s mirrors and its filters made the shimmering star look more red and spiky but the background really stole the show.“You can’t help but see those thousands of galaxies behind it, really gorgeous,” said Jane Rigby, Webb operations project galaxies are several billions of years old. Eventually, scientists hope Webb will see so far away and back in time that it will only be “a couple hundred million years after the big bang”, she first science images won’t come until late June or early $10bn Webb – successor to the nearly 32-year-old Hubble Space Telescope – blasted off from South America in December and reached its designated perch in January.
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.

The White House released the first image of the collection of pictures from the James Webb Space Telescope during a preview event Monday.

Space Telescope Science Institute/NASA, ESA, CSA, STScI, Webb ERO At first glance, the first image from NASA's new James Webb Space Telescope may not seem all that remarkable. But in reality, what appears to be tiny specks in space are actually galaxies — billions of years old. "If you held a grain of sand on the tip of your finger at arms length, that is the part of the universe you are seeing — just one little speck of the universe," NASA Administrator Bill Nelson said of the image on Monday. And more than that, what's picked up in this image are some of the very first galaxies to form in the universe. More images captured by the James Webb Space Telescope should be able to reveal which galaxies in the far, far distance are habitable, Nelson said. The White House, along with NASA, revealed the first of a series of pictures from the telescope since it's launch from Earth more than six months ago. President Biden called Monday's reveal "a historic day." NASA had planned to release the picture today as part of a collection of the first scientific results, but determined the image is so dramatic that Biden should be the one to reveal it to the world. The $10 billion James Webb Space Telescope is the most sophisticated observatory ever launched. It left Earth last December. In late January, it reached its celestial parking place a million miles away from the planet. Since then, engineers have been checking out the instruments, aligning the mirrors and letting the telescope cool down so its instruments will work properly. "Webb was built to find the first generation of galaxies that formed after the big bang," says Jane Rigby, operations project scientist for the telescope. "That is the core science goal it was built to do." Before declaring the telescope open for business mission managers wanted to make what they call early release observations. These are intended to show that the telescope works, and as Rigby says, "are intended to be jaw-droppingly beautiful, powerful both visually and scientifically." The James Webb Space Telescope shown here being tested on earth is expected to reveal some of the most spectacular views of the Universe ever seen.

Chris Gunn/Northrop Grumman, NASA In addition to the image containing the earliest galaxies ever seen, NASA will also release images of a stellar nursery where stars form called the Carina Nebula, the Southern Ring Nebula, and a group of galaxies discovered in 1787 called Stephan's Quintet. There will also be an analysis of the light coming from a giant planet orbiting outside our solar system with the prosaic name WASP-96b. Those additional images are expected to come out on Tuesday morning. Looking Back To The Beginning Webb is designed to gather and analyze infrared light, which is at longer wavelengths than can be seen by the human eye. That will allow it to capture light from the earliest galaxies, which appear in the infrared. Those early galaxies are far away — more than 13 billion light years — and as powerful as the Webb telescope is, they may just look like faint smudges. But those smudges will help astronomers understand more about how the universe as we know it came to be. One early target for the James Webb Space Telescope is a cluster of distant galaxies known as SMACS 0723. The gravitational field of these galaxies acts as a cosmic lens, allowing the telescope to look at far more distant and older parts of the universe.

The gravitational field of these galaxies acts as a cosmic lens, allowing the telescope to look at far more distant and older parts of the universe. STSci One of the astronomers who will be conducting the search for those earliest galaxies is Caitlin Casey, an astronomer at the University of Texas at Austin. She says one way to look for these faint galaxies is to point the telescope at the same patch of sky for a hundred hours or more, and let the light from these distant objects trickle in. The Hubble space telescope showed this so-called deep field approach could identify lots of previously unseen galaxies. But where Hubble was able to see ten thousand galaxies in a deep field, with Webb, "we're going to have a million galaxies," Casey says. Beyond finding new galaxies, Casey wants to understand the large structure of the universe, what the universe would look like if you could step back and get a birds eye view of it. "If you zoom all the way out, the entire universe looks like, you know, something like the interior of a sponge where there are these like little filaments and voids," Casey says. "So what we really want to capture is that structure." Much More To See But that's just the beginning. The breadth of science Webb can be used for is staggering. For example, Megan Mansfield, a NASA Sagan Postdoctoral fellow at the University of Arizona, will be using Webb to study the atmospheres of planets orbiting stars outside our solar system. In particular, she wants to know about their atmospheres — "what they're made of, what their temperature is." That will tell her a lot about the planet itself, and whether it might be capable of sustaining life. Anna Nierenberg of the University of California, Merced, leads a team that has cooked up a clever way to use the new telescope to try to understand the fundamental nature of dark matter, that invisible stuff that makes up a quarter of the universe. "You simply can't do that with any other instrument," she says. "If everything works it will be a big deal." And as with any scientific instrument with new capabilities, no one really knows what secrets the Webb telescope will reveal about the universe we live in.

Astronomers have detected organic molecules in the most distant galaxy to date using NASA’s James Webb Space Telescope, demonstrating the power of Webb to help understand the complex chemistry that goes hand-in-hand with the birth of new stars even in the earliest periods of the universe’s history. The molecules — which are found on Earth in smoke, soot and smog — are in a galaxy that formed when the universe was less than billion years old, about 10 per cent of its current discovery is significant because it may help scientists understand how stars formed in the earliest stages of the universe and casts doubt on a long-held belief that where there’s smoke, there’s fire. The international team, including Dalhousie University astrophysicist Scott Chapman and Texas A&M University astronomer Justin Spilker, found the organic molecules polycyclic aromatic hydrocarbons or PAH in a galaxy more than 12 billion light years away. The galaxy was first discovered by the National Science Foundation’s South Pole Telescope in 2013. "This galaxy is one of the most luminous in the universe, forming stars at a very high rate — 100s of times more rapidly than our own Milky Way. We were hoping to get new insights in the chemistry of the gas supply for forming stars to understand how galaxies like this are forming stars so rapidly," says Dr. Chapman, pictured above right. "Thanks to the high-definition images from Webb, we found a lot of regions with PAH or 'smoke,' but no star formation, and others with new stars forming but no smoke. This is very unlike local galaxies — where if there's PAH, there are stars forming." Einstein ring The discovery, published in the journal Nature, was made possible through the combined powers of Webb and fate, with a little help from a phenomenon called gravitational lensing. Lensing, originally predicted by Albert Einstein’s theory of relativity, happens when two galaxies are almost perfectly aligned from our point of view on Earth. The light from the background galaxy is stretched and magnified by the foreground galaxy into a ring-like shape, known as an Einstein ring. "We were amongst the very first users of the new James Webb Space Telescope. Its capabilities allowed us to detect the molecule in a galaxy that is extremely far away from us, and thus seen in the very early universe, not long after the Big Bang," says Dr. Chapman. "Previously, this molecule had only been detectable in relatively nearby galaxies." The data from Webb found the telltale signature of large organic molecules akin to smog and smoke — building blocks of the same cancer-causing hydrocarbon emissions on Earth that are key contributors to atmospheric pollution. However, the implications of galactic smoke signals are much less disastrous for their cosmic ecosystems and are quite common in space. It was thought their presence was a sign that new stars were being created. The new results from Webb show that this idea might not exactly ring true in the early universe. “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,” said Dr. Spilker, an assistant professor in the Texas A&M Department of Physics and Astronomy. A figure included in the Nature study. Nature The power of the Webb Discoveries like this are precisely what Webb was built to do understand the earliest stages of the universe in new and exciting ways. "This was incredibly exciting to get some of the first observations coming off the new JWST. And extra exciting to see how powerful the telescope is, and how well it works," says Dr. Chapman. The team, which included dozens of astronomers from around the world, says the discovery is Webb’s first detection of complex molecules in the early universe – a milestone moment seen as a beginning rather than an end. "Detecting smoke in a galaxy early in the history of the universe? Webb makes this look easy. Now that we’ve shown this is possible for the first time, we’re looking forward to trying to understand whether it’s really true that where there’s smoke, there’s fire," says Dr. Spilker. "The only way to know for sure is to look at more galaxies, hopefully even further away than this one."

“This infrared image from NASA’s James Webb Space Telescope JWST was taken for the JWST Advanced Deep Extragalactic Survey, or JADES, program. It shows a portion of an area of the sky known as GOODS-South, which has been well studied by the Hubble Space Telescope and other observatories. More than 45,000 galaxies are visible here.” Credits NASA, ESA, CSA, Brant Robertson UC Santa Cruz, Ben Johnson CfA, Sandro Tacchella Cambridge, Marcia Rieke University of Arizona, Daniel Eisenstein CfA. Image processing Alyssa Pagan STScI “Among the most fundamental questions in astronomy is How did the first stars and galaxies form?” NASA writes. The James Webb Space Telescope hasn’t been in space long, but it’s already delivering critical insights into this monumental question. JWST Advanced Deep Extragalactic Survey JADES Searches for Ancient Galaxies A new image captured as part of one of Webb’s most significant scientific programs, the JWST Advanced Deep Extragalactic Survey, or JADES, is not only visually stunning but also incredibly important for scientists working to understand the universe’s history, especially its earliest days. The Webb team explains, “In this image, blue, green, and red were assigned to Webb’s NIRCam Near-Infrared Camera data at and microns; and microns; and and microns F090W, F115W, and F150W; F200W, F277W, and F335M; and F356W, F410M, and F444W, respectively.” This is a 100 percent crop from the full-size Webb image. As part of JADES, Webb will dedicate just over a month of its valuable telescope time to capture and analyze very faint, distant galaxies. Some of the observations have already occurred, and the data continues to roll in from these early images. “While the data is still coming in, JADES already has discovered hundreds of galaxies that existed when the universe was less than 600 million years old. The team also has identified galaxies sparkling with a multitude of young, hot stars,” NASA explains. The area, GOODS-South, has also been imaged by the Hubble Space Telescope, which helps put in perspective just how much more detail Webb offers. This relatively recent image of GOODS-South was captured by Hubble in 2016. It’s a very impressive image, rich with galaxies, but Webb has been able to peer much further back in time thanks to its relatively higher resolution and sensitivity. Credit NASA, ESA/Hubble The Importance of Stars and the Epoch of Reionization “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?” says Marcia Rieke of the University of Arizona in Tucson, co-lead of the JADES program. Ryan Endsley of the University of Texas at Austin led an investigation into the galaxies that existed a mere 500 to 850 million years following the big bang. This period, known as the Epoch of Reionization, remains quite mysterious. Credit NASA, ESA, CSA, Joyce Kang STScI NASA explains reionization, writing, “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 reionization.” 100 percent crop Some scientists believe that supermassive black holes caused the eponymous reionization, others believe that galaxies full of young stars, which burn extremely hotly, were the impetus behind reionization. As part of JADES, Endsley and his colleagues have been studying these all-important distant, old galaxies using Webb’s Near-Infrared Spectrograph NIRSpec instrument. The team wanted to find evidence of star formation and find it they did. “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,” says Endsley. 100 percent crop The bright, massive stars in turn fired torrents of ultraviolet light off into space, which changed the nature of surrounding gas from opaque to transparent. This was achieved through ionization, which is the process of removing electrons from their nuclei. Because early galaxies had so many hot, massive stars, they may have been the primary catalyst for the reionization process that has been hotly debated within the scientific community. “Endsley and his colleagues also found evidence that these young galaxies underwent periods of rapid star formation interspersed with quiet periods where fewer stars formed. These fits and starts may have occurred as galaxies captured clumps of the gaseous raw materials needed to form stars. Alternatively, since massive stars quickly explode, they may have injected energy into the surrounding environment periodically, preventing gas from condensing to form new stars,” writes NASA. 100 percent crop Revealing the Early Universe Another large component of JADES is searching for very early galaxies, which in this context are galaxies that existed less than 400 million years after the big bang. “By studying these galaxies, astronomers can explore how star formation in the early years after the big bang was different from what is seen in current times. The light from faraway galaxies is stretched to longer wavelengths and redder colors by the expansion of the universe — a phenomenon called redshift. By measuring a galaxy’s redshift, astronomers can learn how far away it is and, therefore, when it existed in the early universe,” NASA explains. Credit NASA, ESA, CSA, Joyce Kang STScI Webb has already transformed how scientists search for these very old galaxies. NASA says, “Before Webb, there were only a few dozen galaxies observed above a redshift of eight, when the universe was younger than 650 million years old, but JADES has now uncovered nearly a thousand of these extremely distant galaxies.” In relatively little observation time, Webb has revolutionized the search for ancient galaxies. 100 percent crop Spectrum is an important tool when searching for very old galaxies. “The gold standard for determining redshift involves looking at a galaxy’s spectrum, which measures its brightness at a myriad of closely spaced wavelengths. But a good approximation can be determined by taking photos of a galaxy using filters that each cover a narrow band of colors to get a handful of brightness measurements. In this way, researchers can determine estimates for the distances of many thousands of galaxies at once,” NASA explains. Kevin Hainline of the University of Arizona in Tucson and his colleagues used Webb’s Near-Infrared Camera NIRCAM, to obtain these critical spectral measurements, which are called photometric redshifts. Hainline’s team identified more than 700 galaxies that they believe existed when the universe was between 370 million and 650 million years old. The huge number of candidate galaxies far outstrips even the most optimistic estimates scientists had prior to Webb’s launch. Webb’s groundbreaking resolution and spectral sensitivity are paying huge dividends. “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,” says Hainline. “Now, we can see that some of them are actually extended objects with visible structure. We can see groupings of stars being born only a few hundred million years after the beginning of time.” Image credits NASA, ESA, CSA, Brant Robertson UC Santa Cruz, Ben Johnson CfA, Sandro Tacchella Cambridge, Marcia Rieke University of Arizona, Daniel Eisenstein CfA.
