  • How NASA’s Webb Telescope Will Transform Our Place in the Universe

    14:55

    NASA's James Webb Space Telescope is the most powerful telescope in the history of humanity, and one of the most ambitious engineering projects ever attempted. It will witness the birth of stars and galaxies at the edge of time and probe alien skies for signs of life. In this new documentary from Quanta, JWST’s lead scientists and engineers discuss what inspired the telescope, how it was built, the extraordinary challenges it will face upon launch, and its potential discoveries.

  • How The Golden Eye Of The James Webb Space Telescope Will See The Edge Of The Universe

    7:48

    NASA’s James Webb Space Telescope is a time machine to the early universe, which uses massive golden mirrors to capture ancient light. The results will likely rewrite and expand our textbooks for years to come.

    An international project like this that has countless “firsts” takes time, but the painstaking effort to design, construct and test Webb’s optical system will be worth the wait. Overnight, the eye of the telescope will revolutionize our understanding of the cosmos and be set loose on the biggest questions in astronomy.

    The astronomical community was after something that hadn’t been observed before… the early universe. The first stars and galaxies started to form 100 to 250 million years after the Big Bang, around 13.6 billion years ago. Because the universe is expanding, actually the light from the early universe gets stretched into the infrared and that's called a cosmological redshift. It's this cosmological redshift that Webb's optics will be hunting for, to uncover the story of the early universe. Infrared light can pass through dust in the universe. And so it allows us to peer through dust clouds and see, for example, stellar nurseries.

    No other telescope today has the collecting power and sensitivity that NASA’s JWST has to lift the veil on the universe’s secrets. The James Webb Space telescope is sensitive enough that if there were a bumblebee at the distance of the moon, we would be able to detect it. The telescope’s core superpowers come from its advanced optical system.

    Webb vs Hubble Telescope

    “Webb often gets called the replacement for Hubble, but we prefer to call it a successor. After all, Webb is the scientific successor to Hubble; its science goals were motivated by results from Hubble.”

    The Five Big Ways the James Webb Telescope Will Help Astronomers Understand the Universe

    “The further into space scientists can look, the further back in time they can observe a galaxy. Webb, being the farthest seeing telescope yet, can root out the youngest looking galaxies humanity can observe.”

    The Webb Space Telescope Will Rewrite Cosmic History. If It Works.

    “The James Webb Space Telescope has been designed to answer many of the core questions that have animated astronomers over the past half-century. With a $10 billion price tag, it is one of the most ambitious engineering initiatives ever attempted. But for it to achieve its potential — nothing less than to rewrite the history of the cosmos and reshape humanity’s position within it — a lot of things have to work just right.”

    The $11-billion Webb telescope aims to probe the early Universe

    “If everything goes to plan, Webb will remake astronomy by peering at cosmic phenomena such as the most distant galaxies ever seen, the atmospheres of far-off planets and the hearts of star-forming regions swaddled in dust. Roughly 100 times more powerful than its predecessor, the Hubble Space Telescope, which has transformed our understanding of the cosmos over the past 31 years, Webb will reveal previously hidden aspects of the Universe.”

  • James Webb Telescope Will Make TERRIFYING Discoveries!

    12:56

    Decades after the idea, the James Webb Space Telescope has finally made it to space. Launched on this Christmas, the telescope started its deployment after it was sent to the space. Scientists are depending on the telescope to know the truth about our existence and also if there is any other life in this universe other than ours. The telescope fans are curious to know about its deployment and what’s next for this masterpiece, they are asking if the telescope is really going to find the answer to our creation? Welcome to Cosmos lab, your one station for all the news from space. Join us in today’s video to find out about the deployment of the James Webb Space Telescope, its goals, and what’s next for this massive beast.
    The James Webb Space Telescope is the world's most powerful and largest space telescope. It is an infrared space observatory that launched on Dec 25, 2021, from ESA's launch site at Kourou in French Guiana, onboard an Arianespace Ariane 5 rocket. The telescope will let scientists to peek back 200 million years after the Big Bang to see how our cosmos looked. Images of some of the first galaxies ever formed will be captured by the telescope. It will also be able to peek inside dust clouds to see where new stars and planets are developing, as well as investigate the atmospheres of planets orbiting other stars. It will be able to observe objects in our solar system from Mars outward.
    The $10 billion James Webb Space Telescope will explore the cosmos to learn more about the universe's history, from the Big Bang to the birth of alien planets and beyond. It's one of NASA's Great Observatories, huge space instruments that include the likes of the Hubble Space Telescope to peer deep into the cosmos.
    After being launched on Christmas Day, the James Webb Space Telescope will journey over a million miles or 1.5 million kilometers to its permanent home, a Lagrange point — a gravitationally stable place in space. At the second Lagrange point, the James Webb Space Telescope will orbit the sun (L2). L2 is a location in space near Earth that is opposite the sun; this orbit will keep the telescope in alignment with Earth as it orbits the sun. Several other space telescopes have used it, notably the Herschel Space Telescope and the Planck Space Observatory. If Webb gets to the right zone, it can use a minimum of fuel to stay in place thanks to a near-perfect alignment with the sun, Earth and moon.
    The new observatory, the world's largest space telescope, successfully unfolded its final primary mirror piece on January. 8, capping one of NASA's most challenging space deployments ever. After the deployment, Engineering teams cheered back at the Space Telescope Science Institute in Baltimore, Maryland as the National Aeronautics and Space Administration announced on Twitter that the final wing was deployed.
    ‘Final wing is now deployed! Short celebration, but we’ve still got work to do. Engineers are working to latch the wing into place, a multi-hour process. When the final latch is secure, NASA Webb will be fully unfolded in space.’
    Webb's five-layered sunshield — a 70-foot-long, kite-shaped structure that acts as a parasol — was deployed to keep the telescope's equipment cool so they could detect tiny infrared signals from the remote reaches of the Universe. The sun shield will be permanently installed between the telescope and the Sun, Earth, and Moon, with the Sun-facing side designed to resist temperatures of up to 230 degrees Fahrenheit (110 degrees Celsius).
    The telescope was folded up because it was too large to fit into the nose cone of a rocket in its working condition. According to Nasa, unfurling has been a sophisticated and difficult process - the most difficult of its kind ever attempted. However, it has now been successfully deployed and according to NASA officials, we have still got work to do.
    So, what is this work, and what is next for this gigantic space telescope? Webb is expected to arrive at its insertion location by Jan. 23. John Durning, Webb's deputy project manager at NASA's Goddard Space Flight Center, after the deployment in a press conference from Webb's control center at the Space Telescope Science Institute in Baltimore, Maryland, said to the reporters that,
    ‘As Webb prepares for the engine fire, team members will spend the next 15 days aligning the 18 mirror segments to essentially perform as one mirror.' I should say also, that Webb will start turning on the instruments in the next week or so, Durning added. And then after we get into L2, as the instruments get cold enough, they [engineers] are going to be starting to turn on all the various instruments.’
    L2 is an excellent area for Webb to carry out its mission.

  • James Webb Telescope Terrifying Discoveries Will Change Everything!

    8:01

    The James Webb telescope has been conceptualized for more than a decade. Its fans would be happy to hear that it has finally been launched into the dark abyss known as space. It was launched last christmas, and it began its deployment immediately after it entered space. We hope that this telescope would allow us to know a lot more about both our existence, and the possibility of external life outside us.

    Since the launch of this $10 billion telescope, its fans have asked nonstop about its progress, and if it really will do what it was set out to do. Join us as we explore all the possibilities of this telescope and give some insight on how this telescope will finally make terrifying new discoveries.


    If you’re interested in space travel, you should know that there are a lot of limitations to this particular concept, one of which is the ability to view planets and stars past our solar system. It was even a challenge to view events occurring past mars due to the absence of light. Astronomers, engineers, and astronauts have dreamed of being able to see past our solar system. Now, the James Webb telescope is capable of making it possible.

    For those who don't know, the James Webb telescope was designed to the largest telescope ever created. It got launched on December 25th last year from the ESA space site at Koolu via an Arianespace Ariane 5 Rocket. If this telescope performs its purpose, it would allow us to be able to take a look at the events of the big bang. Imagine seeing how the events occurred during the big bang which happened as far back as 200 million years ago.

    We would be able to view the first galaxies that were born out of the big bang, and also look at any new planets or stars developing. This would be a phenomenal achievement, and would be such good news for science.

    Its journey spans over a million miles to a gravitationally stable point in space. Arriving at that point in space would keep it from leaving the solar system, and will keep it stable enough to take a look at several galaxies. The telescope would then land on a second gravitationally stable point, L2. L2 is a position in space that is in close proximity and alignment with earth and is directly opposite the sun. At this point, it will be able to orbit the sun even more closely.

    Interestingly, other telescopes have used this particular area at several points in time and have captured mind-blowing information. If it gets to this point perfectly, it would use the gravitational stability of that point as well as minimum fuel to stay in perfect alignment with the sun, moon, and the earth.
    Its successful launch from the earth took about 31 minutes, and scientists, engineers, and fans from all over the world cheered all the way through. We know you might be wondering how its going to survive the full force of the sun. The telescope’s designers understood this, and built a 5-layer, 70-foot long sun shield. It keeps the equipment of the telescope cool and prevents the telescope itself from getting destroyed due to the heat from the sun.

    This sun shield has been checked and given the okay by multiple engineers and scientists from around the world due to its ability to protect itself from temperatures of up to 250 degrees Fahrenheit. If you’re watching the video, you would probably notice that the telescope is way bigger than a rocket can fit. Because of that, it was designed in such a way that it can be folded up and safely transported in a rocket. According to NASA, opening it up has been one of the most sophisticated processes they have undergone. What’s more is that the process isn’t over yet, as they have said they still have some work to do.

    What’s Next?

    Although this telescope has not arrived at its destination yet, it is expected to arrive by January 23rd. The deputy project manager at NASA’s space flight centre said in a conference that between the start of January and the 23rd, the team would spend its time aligning the 18 mirror segments in order to successfully form one giant mirror.
    Beryllium was used to produce these mirrors because it is a lightweight metal, and it is fairly resistant to the sun’s rays.
    After it has been fully unfolded and assembled, its different compartments will be turned on. The engineers believe that this will happen between 7-14 days.

    The distance from the sun ensures that enough darkness is gotten for the heat seeking infra-red studies to be performed. These infra-red telescopes would allow the telescope to view distant galaxies, stars, and planets.

    This telescope will be the most powerful telescope ever created, and it has already started breaking records. It surpasses the capabilities of the hubble space telescope, among many others.

  • Can The James Webb Telescope POSSIBLY See The Creation Of The Universe?

    10:11

    What is the origin of this universe? What was it like before the big bang, and are we alone in this vast universe? These are just a few of the many questions that have kept some scientists awake at night for years. They devised numerous initiatives and missions in order to learn as much as possible about our existence and creation, but there wasn’t any technology that can show us all that. It took decades for the scientists to build a massive telescope, the James Webb Space Telescope that is supposed to explain to us the creation of this universe. But the question is, is this JWST capable of doing so? Welcome to Cosmos lab, your one station for all the news from space. Join us in today’s video to find if the James Webb Telescope can answer our creation or not.
    The James Webb Space Telescope (JWST) has begun its mission to image the birth of the universe after a nail-biting launch on Christmas Day. The $10 billion James Webb Space Observatory, NASA's largest and most powerful space research telescope, will explore the cosmos to learn about the universe's history, from the Big Bang to the birth of alien planets and beyond. It is one of NASA's Great Observatories, huge space instruments that include the likes of the Hubble Space Telescope to peer deep into the cosmos.
    JWST will go back in time more than 13.5 billion years to witness the faint infrared light from the first galaxies, illuminating a previously unseen period of cosmic history that shaped the universe as we know it today. According to NASA, JWST was designed not to see the beginnings of the universe, but to see a period of the universe's history that we have not seen yet before.
    The concern here is that can James Webb perform these functions or how is it going to see through thousands of light-years? James Webb Space Telescope is a cosmic time machine that can view galaxies and stars as they were as few as 100 million years after the Big Bang, the universe's unimaginably catastrophic birth.
    Webb will cover longer wavelengths of light than Hubble and will have greatly improved sensitivity. NASA said on its website, the longer wavelengths will enable Webb to look further back in time to see the first galaxies that formed in the early universe.
    John Mather, the mission’s senior project scientist at NASA’s Goddard Space Flight Center in Maryland said, “This telescope is so powerful that if you were a bumble bee 240,000 miles away, which is the distance between the Earth and the moon, we will be able to see you.”
    How is this even possible? The JWST is equipped with four science instruments that will enable observations in visible, near-infrared, and mid-infrared wavelengths. Infrared light is electromagnetic radiation with wavelengths longer than visible light but shorter than radio waves.
    Paul Geithner Deputy Project Manager - Technical for the James Webb Space Telescope at NASA's Goddard Space Flight Center explains that there are several reasons to study in the infrared. One reason is that the ultraviolet and visible light released by the universe's first luminous objects when it was young has been stretched by the expansion of the cosmos and now reaches us as infrared light, nearly 13 billion years later. Webb will be on the lookout for the first rays of light.
    Another explanation is that stars and planets are formed in gas and dust clouds, which obscure our perspective. We can see inside these clouds because infrared light penetrates them. It's unclear how the cosmos evolved from a simpler state of hydrogen and helium to the universe we see today, but the Webb telescope will glimpse far-flung realms of space and a period of time never seen before, assisting us in answering these crucial questions.
    Webb will conduct ultra-deep near-infrared surveys of the Universe in order to find the first galaxies, followed by low-resolution spectroscopy and mid-infrared photometry. High-resolution near-infrared spectroscopy will be required to investigate reionization.
    With this, the James Webb Space Telescope is going to see things that have never been seen before. So maybe it will help us to finally find out about our existence.
    John Mather says, “what are we going to do with this great telescope? We’re going to look at everything there is in the universe that we can see.” He further said, “We want to know how did we get here. The Big Bang, how did that work? So we’ll look. We have ideas, we have predictions, but we don’t honestly know.”
    To find the answers, the science mission of JWST is divided into four sections. First light and reionization. Assembly of galaxies. Birth of stars and protoplanetary systems and Planets and origins of life.
    First light refers to the universe's early stages after the Big Bang when the universe as we know it today began.

  • James Webb Just Completed the Most Difficult Task of its Mission

    5:27

    The iconic James Webb Space Telescope has completed the most challenging task of its mission: deploying the massive sunshield. The giant kite-shaped and tennis-court-sized sunshield is now sailing in full bloom towards Webb's final destination.

    It started with the unfolding of the two pallet structures: forward and aft. This resulted in bringing the observatory to its full length of 70-feet. Then, the Deployable Tower Assembly separated the telescope and instruments from the sunshield and the main body of the spacecraft, thereby creating room for the sunshield to fully deploy. Following this, the aft momentum flap and membrane covers were released and deployed. The mid-booms deployment allowed the sunshield to extend to its full width of 47 feet. Finally, on January 4, 2022, at approximately 11:59 a.m. EST, the sunshield was fully tensioned and secured into position. This marked the completion of the intense task of sunshield deployment.

  • «James Webb Space Telescope» startet in den Weltraum | WELT LIVE DABEI

    2:14:26

    Nach jahrzehntelanger Planung, Kostenexplosionen und mehrerer Startverschiebungen soll das bislang größte und leistungsfähigste Teleskop der Raumfahrtgeschichte am Samstag (13.20 Uhr deutscher Zeit) ins Weltall aufbrechen. Das «James Webb Space Telescope» (JWST) - eine rund zehn Milliarden Dollar teure Kooperation der Weltraumagenturen der USA, Kanadas und Europas - soll an Bord einer «Ariane»-Trägerrakete vom Weltraumbahnhof Kourou in Französisch-Guayana starten.

    Bis zum Zielorbit in 1,5 Millionen Kilometern Entfernung soll das JWST rund vier Wochen unterwegs sein. Erste Daten und Bilder des Teleskops werden frühestens im Sommer erwartet.

    Das JWST soll Nachfolger des «Hubble»-Teleskops werden, das seit mehr als 30 Jahren im Einsatz ist. Es soll unter anderem mit Hilfe eines 25 Quadratmeter großen Spiegels Bilder aus dem frühen Universum liefern. Wissenschaftler erhoffen sich davon neue Erkenntnisse über die Entstehung unseres Universums. Die Lebensdauer von «James Webb» ist erstmal auf etwa zehn Jahre angelegt.

  • Why The James Webb Telescope Will LIKELY Find Alien Life!

    11:14

    The universe is utterly and terrifyingly vast. Humans' inquisitive nature has driven them to learn anything they can about everything in this universe, or even before this known universe. And the most important of all, to find the answers to are we alone in the universe question. Scientists have been working around the clock and spending billions of dollars to learn more and more about our planet's origins, the big bang theory, the intergalactic space, and everything that is beyond. Seems like their hard work paid off in the form of a giant telescope. The James Webb Space Telescope. Welcome to Cosmos lab, your one station for all the news from space. Join us in today’s video to find out about the massive telescope that is going to answer the existential questions.
    The James Webb Space Telescope, an engineering masterpiece and the most powerful space observatory ever built, will help answer fundamental questions about the Universe by peeking back 14 billion years. Work on the project began over 30 years ago at Space Telescope Science Institute with a challenge from Institute Director Riccardo Giacconi to “think about the next major mission beyond Hubble.” The masterpiece James Webb is the product of the combined scientific prowess of NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) – and by extension, Université de Montréal. The components supplied by the CSA, NASA, and the ESA combine to make the most complex, precise, and powerful space observatory ever built, promising groundbreaking astronomical discoveries.
    René Doyon, Director of UdeM's Institute for Research on Exoplanets (iREx) and a professor in the Physics Department, is the primary investigator on the Canadian scientific team, which supplied a scientific instrument and a guiding sensor to the enormous observatory.
    The observatory's unmatched power will allow scientists all over the world to peer into the furthest reaches of the universe to discover more about the composition and habitability of exoplanets, as well as analyze the life cycle of stars.
    The telescope will explore many things but the important of all will be the search for life on other planets. Webb will conduct in-depth research on the planets in our solar system and other planetary systems. It will also detect the presence of extraterrestrial bodies. Furthermore, Doyon's team's scientific equipment is capable of analyzing a wide range of celestial bodies, including the atmospheric composition of distant exoplanets.
    Nathalie Ouellette, an astrophysicist who does communications for the James Webb said, “What we’re looking for, our holy grail, are ‘biosignatures,’ that is, signs of extraterrestrial life. We’re talking about finding signs of biological activity or the signature of certain molecules. Based on the presence of such molecules, particularly in certain combinations, we may be able to determine that conditions are conducive to the development of life when we explore an exoplanet using the telescope.”
    Telescopes are also time machines of a sort. Natasha said, “Looking into space is like looking into the past.’ Light waves travel so quickly that they appear to flash from one spot to another to the human eye. However, in space, the distances are so great that the time it takes for light to travel is noticeable. That makes the Webb a marvelous time machine. It will be able to travel back in time 200 million years after the Big Bang, which is unprecedented.
    As a result, the Webb will help us better understand how the first luminous objects, the galaxies, evolved throughout time. The telescope, according to Ouellette, will also provide information on the formation of our own solar system. JWST will also target each of the seven rocky, roughly Earth-size worlds in the TRAPPIST-1 system.

  • Tower Extension Test a Success for NASA’s James Webb Space Telescope

    1:00

    To test the James Webb Space Telescope’s readiness for its journey in space, technicians successfully commanded it to deploy and extend a critical part of the observatory known as the Deployable Tower Assembly.

    The primary purpose of the deployable tower is to create a large gap between the upper part of the observatory that houses its iconic gold mirrors and scientific instruments, and the lower section known as the spacecraft bus which holds its comparatively warm electronics and propulsion systems. By creating a space between the two, it allows for Webb’s active and passive cooling systems to bring its mirrors and sensors down to staggeringly cold temperatures required to perform optimal science.

    Webb was designed to look for faint traces of infrared light, which is essentially heat energy. To detect the extremely faint heat signals of astronomical objects that are incredibly far away, the telescope itself has to be very cold and stable.

    During the test, the tower was slowly extended 48 inches (1.2 meters) upward over the course of several hours, in the same maneuver it will perform once in space. Simulating the zero-gravity environment Webb will operate in, engineers employed an innovative series of pulleys, counterbalances and a special crane called a gravity-negation system that perfectly offloaded all of the effects of Earth’s gravity on the observatory. Now that Webb is fully assembled, the difficulty of testing and properly simulating a zero-gravity environment has increased significantly.

    “The Deployable Tower Assembly worked beautifully during the test,” said Alphonso Stewart the Webb deployment systems lead for NASA's Goddard Space Flight Center in Greenbelt, Maryland. “It performed exactly as predicted, and from our expectations from previous tests before the full observatory was assembled. This was the first time that this part of Webb was tested in its flight-like configuration to the highest level of fidelity we possibly could. This test provides the opportunity to assess all interfaces and interactions between the instrument and bus sections of the observatory.

    In addition to helping the observatory cool down, the Deployable Tower Assembly is also a big part of how Webb is able to pack down into a smaller size to fit inside an Ariane 5 rocket for launch. Webb is the largest space science observatory ever built, but to fit a telescope that big into a rocket, engineers had to design it to fold down into a much smaller configuration. Webb’s Deployable Tower Assembly helps Webb to just barely fit inside a 17.8-foot (5.4-meter) payload fairing. Once in space, the tower will extend to give the rest of Webb’s deployable parts, such as the sunshield and mirrors, the necessary amount of room needed to unpack and unfold into a fully functional infrared space observatory.

    Mostly known as the successor of the incredibly popular Hubble Space Telescope, Webb will observe the universe with detectors that target near and mid infrared wavelengths. This means that the instruments on board Webb are specially designed to combat some of the historic challenges astronomers have faced when trying to observe the early universe, like huge dust clouds that block the view of celestial objects, cosmological redshifting, and even interference from other bodies.

    In fact, there are three things necessary to create the perfect environment for an infrared telescope; a large mirror to collect as much light as possible, extremely cold temperatures, and a clear line of sight to your target. Each detail has been thought out meticulously over the past two decades leading to this point, like orbital selection. 1.5 million kilometers is a bit of a trip to say the least.

    So why are we putting Webb in such a distant orbit? Well, it’s heading to L2, the second Lagrange point around the Sun and Earth. These five points are stable configurations that allow bodies to orbit each other, but still remain in the same position relative to one another. The key to L2 is centripetal force, which you can imagine as the tension in a rope on a tether ball that keeps it connected to the pole. At L2, the centripetal force required for a small satellite-sized object to move with respect to the Earth is equal to the gravitational pull of the two larger masses. Meaning that this particularly cozy orbit has several benefits to support Webb’s mission.

    The largest space telescope in history is about to blow our minds

    'The Webb represents the culmination of decades, if not centuries, of astronomy,' says Sara Seager, a planetary scientist and astrophysicist at MIT. 'We’ve been waiting for this a very long time.'

    NASA's new telescope will show us the infancy of the universe

    The J.W.S.T. will then continue on its own, for twenty-nine days, toward a lonely, lovely orbit in space, about 1.5 million kilometres from Earth, where we will never visit it, though it will stay in constant communication with us. From Earth, it will appear ten thousand times fainter than the faintest star.

    The Five Big Ways the James Webb Telescope Will Help Astronomers Understand the Universe

    Webb’s conception is inspired by the Hubble Space Telescope—the 31-year-old observatory famous for capturing stunning photos of our universe's galaxies. But Webb picks up where its predecessor falls short, says Eric Smith, Webb’s program scientist and chief scientist of NASA’s Astrophysics Division. There’s really no telescope like Webb so far, he says.

  • James Webb Telescope Terrifying Discovery Before Big Bang Will Change Everything!

    8:46

    How did this universe begin? Were we alone in this huge cosmos before the
    Big Bang? Just some of the numerous questions that scientists have been
    pondering for years, like this one: They planned a slew of projects and
    missions to gather as much information as possible about our origins and the
    universe we live in, but no technology existed to do it. The James Webb
    Space Telescope, a large telescope was then built by scientists and is
    expected to help us understand the origins of the cosmos.
    The projected Christmas Day 2021 launch of the $10 billion James Webb
    Space Telescope was both exhilarating and worrisome for the thousands of
    scientists, engineers, managers, and support staff who worked on the project
    for almost a decade. The scientific potential of the JWST is vast, and it could
    provide answers to some of the most fundamental problems in the universe's
    evolution. But the real question is, can this JWST achieve it? Is it possible that
    James Webb will be able to see thousands of light-years into the future? We'll
    be discussing this in today's video.
    But before we begin, kindly subscribe to this channel, like this video, and
    enable the notification feature If you haven't already. Come on, let's get
    started!
    A new era of astronomy is just around the corner, provided everything goes
    according to plan. After a nail-biting launch on Christmas Day, the James
    Webb Space Telescope (JWST) has launched its mission to capture the birth
    of the universe. James Webb Space Observatory will be NASA's largest and
    most powerful space research telescope, exploring the cosmos to learn more
    about the universe's history, from its Big Bang to the birth of alien planets
    and beyond. The observatory will cost $10 billion. It is a part of NASA's Great
    Observatories, which comprise the Hubble Space Telescope and other
    massive space telescopes that can stare into the universe.
    One of JWST's primary goals is the exploration of galaxy formation more than
    13.5 billion years before the Big Bang, a hitherto unobserved period of
    cosmic history that formed our universe as we know it today. According to
    NASA, JWST was built to observe a time in the universe's history that has not
    yet been observed before, rather than to study the origins of the cosmos.
    We prefer to think of the JWST as a successor to the Hubble Space
    Telescope, rather than a replacement. More than 30 years after its launch,
    the Hubble Space Telescope has provided us with breathtaking views of the
    universe and countless scientific discoveries. It is our hope and expectation
    that it will continue for many more years to come.
    However, the telescope's 2.4-meter diameter mirror, compared to ground-
    based telescopes, limits its sensitivity and ability to observe the faintest
    objects. This is a limitation. Even though Hubble can observe infrared light, it
    cannot access the light wavelengths from the very first stars and galaxies.
    Hubble has some capability to observe infrared light. JWST, on the other
    hand, will be able to do this task. For the first time, we may even be able to
    observe stars that were generated from primordial material from the Big
    Bang.
    Knowing when and how the first stars originated soon after the Big Bang is
    an important scientific subject and one of the key science aims of JWST.
    Carbon, silicon, and gold, which are essential to life and contemporary
    technology, were produced in the early stars, but how they did so is still a
    mystery to us.
    As a result, the design of this observatory has been influenced greatly by the
    fact that it needs to be extremely cool to reduce the amount of unwanted
    background light.
    It's not just the initial stars and galaxies that will be studied by JWST.
    Researchers from all over the world can apply for time at this observatory,
    which is designed to serve a variety of purposes. Infrared observation will
    allow JWST to see through the clouds of dust that enshroud very young stars,
    which are impenetrable to the visible light of the telescope.
    That means it will be able to see directly into star-forming regions,
    something Hubble hasn't been able to do yet. The findings will provide light
    on the formation of stars and the systems of planets that orbit them as a
    result of the collapse of dust and gas clouds.
    Webb will be able to see further into the universe than Hubble, and it will be
    far more sensitive. This will allow Webb to go back much further in time and
    view the earliest galaxies that formed in the early universe, according to

    This is pretty much what the James Webb telescope is offering us: the chance to see such pictures for the whole universe. Have you ever heard about it? It will be our best ever space telescope. And now, we have a launch date: December 18, 2021. 

    The James Webb Space Telescope, also called Webb or JWST, is a large, space-based observatory, optimized for infrared wavelengths, which will complement and extend the discoveries of the Hubble Space Telescope. 
    As you can see from these two pictures, James Webb and Hubble are pretty different telescopes. 
    Webb will primarily look at the Universe in the infrared, while Hubble studies it primarily at optical and ultraviolet wavelengths. Webb also has a much bigger mirror than Hubble. This larger light-collecting area means that Webb can peer farther back into time than Hubble is capable of doing. Hubble is in a very close orbit around the earth, while Webb will be 1.5 million kilometres away at the second Lagrange point. 
    At its peak, as many as 2,000 scientists and technicians were working on Webb, with a total of about 10,000 people involved in its construction over the decades. 
    It will have longer wavelength coverage and greatly improved sensitivity.

    NASA JAMES WEBB SPACE TELESCOPE
    “COMMUNICATIONS ISSUE” DELAYS LAUNCH — AGAIN

    The James Webb Space Telescope, the multi-billion-dollar instrument on which the hopes and dreams of astronomers worldwide rest, has had to delay its launch again!
    From 2018 until now, this is the 7th time James Webb has been delayed!
    What the hell is going on with NASA?
    Let’s find the answer in today’s episode of Great SpaceX!

    The Dec. 22 launch will not happen!
    Engineers discovered an intermittent data dropout associated with a piece of ground support equipment after connecting the James Webb Space Telescope with its Ariane 5 launcher over the weekend in French Guiana.
    As a result, the observatory’s long-awaited blastoff will be delayed at least two days to Dec. 24 to troubleshoot the problem.
    The mission was previously set for takeoff on Dec. 22 from the European-run Guiana Space Center in Kourou, French Guiana, on the northeastern coast of South America.
    Everything had been going so well. The telescope was fueled up, boxed up. And the final step in preparation for Webb’s blastoff also occurred Saturday (Dec. 11) when the observatory was raised atop its Ariane 5 launch vehicle.
    But a technical issue held up the next step in the launch campaign.
    In a brief statement, NASA wrote on its website late Tuesday that the Webb team is “working on a communications issue between the observatory and the launch vehicle system.”
    Thomas Zurbuchen, the associate administrator for NASA’s science mission directorate, said Tuesday that engineers found an “interface problem” in a system that communicates with Webb while it’s on top of the Ariane 5 rocket.
    “The way to think about it is it’s a ground support equipment thing… Basically, the data cables are dropping some frames.”
    Technicians inside the Ariane 5 rocket’s final assembly building in Kourou have tried to diagnose the problem, but so far, haven’t been able to resolve it.
    “Tomorrow, we’re going up there with the ground support equipment, and just really making sure we can flush out where the issue is,” Zurbuchen said. “We’ve tried a bunch of things, and we just haven’t been successful. This is a 100-meter cable that goes all the way from the top of the rocket to somebody’s computer. Somewhere in there (is the problem), is our guess.

    The James Webb Space Telescope is finally ready for launch on December 18, 2021. A joint project of NASA, the European Space Agency, and the Canadian Space Agency, the James Webb Space Telescope is the most ambitious, complex, and expensive telescope ever built. It is a time machine that will take us back to our origins, observe some of the oldest galaxies in the universe, image new planets forming around other star systems, and even probe the planets of our solar system. In addition, it will shed light on some of the most exciting mysteries of our universe.

    However, the telescope's journey from being proposed to finally being ready for launch has been quite a roller coaster ride. Every launch requires meticulous planning and preparation. But for Webb, this process began about 25 years ago.

  • Watch again: Nasa launches James Webb Space Telescope in historic Christmas Day lift-off

    35:13

    Nasa successfully launched the James Webb Space Telescope, which the US space agency hopes will unlock the secrets of the early universe.

    Nasa administrator Bill Nelson warned ahead of the launch that “over 300 things” could go wrong and scupper the launch of the $10 billion observatory, which was previously pushed back from 24 December due to poor weather conditions at the launch site in French Guinea.

    Once in space, the James Webb telescope will attempt to look back in time 13.7 billion years towards stars and galaxies formed during the early stages of the universe’s creation.

  • Webb`s Success. Webb Telescope Will Transform Our Place in the Universe

    7:51

    5 critical stages will determine the success or failure of NASA’s James Webb Space Telescope. After decades of development, whether NASA’s James Webb Space Telescope succeeds or fails all comes down to 5 critical milestones that are only days away. Success means humanity’s most powerful space observatory ever. NASA's James Webb Space Telescope is the most powerful telescope in the history of humanity, and one of the most ambitious engineering projects ever attempted. It will witness the birth of stars and galaxies at the edge of time and probe alien skies for signs of life. Failure means the most expensive space junk in history. These five critical stages will determine its fate. Webb subsequently burns fuel for course corrections: the same fuel needed for telescope operations. An unsuccessful deployment will cause power failure after mere hours, ending Webb’s life prematurely. After deploying support structures and the tower assembly, a cumulative 178 sunshield releases must fire. If any fail, or if tensioning catches or snags, the telescope won’t cool: a catastrophic loss. The primary mirror must deploy, making a single, smooth surface to 20 nanometer precision. 29 days post-launch, Webb’s thrusters fire, entering orbit around L2: its ultimate destination. If these five mission-critical stages succeed, we will have the most powerful space observatory ever. The James Webb Space Telescope.

    NASA's James Webb Space Telescope is the most powerful telescope in the history of humanity, and one of the most ambitious engineering projects ever attempted. It will witness the birth of stars and galaxies at the edge of time and probe alien skies for signs of life. In this new documentary from Quanta, JWST’s lead scientists and engineers discuss what inspired the telescope, how it was built, the extraordinary challenges it will face upon launch, and its potential discoveries.

    Read the feature article at Quanta:

    explores innovative science and art collaborations, such as his work with Syren Modern Dance in Ticktock, a performance exploring the nature of time through movement and narration.

    James Webb Telescope: All about NASA's most powerful space telescope in pursuit of cosmological discovery:
    Opening a new of astronomy, NASA's James Webb Space Telescope was launched by rocket early Saturday from the northeastern coast of South America. The unique Space Telescope promises to provide first glimpse of the universe as it existed when the earliest galaxies formed

    The event was telecasted live on a joint NASA-ESA webcast with a countdown conducted in French. From a tropical rain forest to the edge of time itself, James Webb begins a voyage back to the birth of the universe, a NASA commentator said as the two-stage launch vehicle, fitted with double solid-rocket boosters, roared off its launch pad into cloudy skies.

    After a 27-minute, hypersonic ride into space, the 14,000-pound instrument was released from the upper stage of the French-built rocket about 865 miles above the Earth, and should gradually unfurl to nearly the size of a tennis court over the next 13 days as it sails onward on its own.
