Map of the Universe from Johns Hopkins University and others.....

Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.

James Webb Space Telescope Tracker Live Position & Data

Webb Makes First Detection of Crucial Carbon Molecule A team of international scientists has used NASA’s James Webb Space Telescope to detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation of more complex carbon-based molecules. Methyl cation was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula. Carbon compounds form the foundations of all known life, and as such are particularly interesting to scientists working to understand both how life developed on Earth, and how it could potentially develop elsewhere in our universe. The study of interstellar organic (carbon-containing) chemistry, which Webb is opening in new ways, is an area of keen fascination to many astronomers.

Will The James Webb Telescope Finally Be Launched

Will The James Webb Telescope Finally Be Launched. Decades of waiting have finally led us to this moment. Now, we are only a month away from witnessing history. The US, European, and Canadian space agencies have come together to create the James Webb Space Telescope dubbed by many as the “telescope that ate astronomy”. At 6.5 meters in diameter, it’s astronomical mirror is the largest ever and will unfold to reveal an origami-like structure. That is if the JSWT (James Webb Space Telescope) does, in fact, launch. Fingers crossed that it can finally begin its mission and leave our earthly world behind. But why has it taken so long to launch? And why are we now sure that it will be launched this December? Let’s find out in this video.

NASA Engineers Conduct Low Light Test on New Technology for Webb Telescope

NASA engineers inspect a new piece of technology developed for the James Webb Space Telescope,
the micro shutter array, with a low light test at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Developed at Goddard to allow Webb's Near Infrared Spectrograph to obtain spectra of more than 100 objects in the
universe simultaneously, the micro shutter array uses thousands of tiny shutters to capture spectra from selected objects
of interest in space and block out light from all other sources.

What Will the James Webb Space Telescope See? A Whole Bunch of Dust, That’s What

When it comes to the first galaxies, the James Webb Space Telescope will attempt to understand the formation of those galaxies and their link to the underlying dark matter. In case you didn’t know, most of the matter in our universe is invisible (a.k.a. “dark”), but its gravity binds everything together, including galaxies. So by studying galaxies – and especially their formation – we can get some hints as to how dark matter works. At least, that’s the hope. It turns out that astronomy is a little bit more complicated than that, and one of the major things we have to deal with when studying these distant galaxies is dust. A lot of dust.

Phew! James Webb passes its final thermal vacuum test.
Still on track for 2021

Once it is deployed to space, the James Webb Space Telescope (JWST) will be the most sophisticated and advanced space telescope in operation. Carrying on in the tradition of Hubble, Kepler, and Spitzer, the JWST will use its advanced suite of infrared imaging capabilities to study distant exoplanets, learn more about the Solar System, and study the earliest galaxies in the Universe.

First assembly August 2019

Image: The fully assembled James Webb Space Telescope with its sunshield and unitized pallet structures (UPSs) that fold up around the telescope for launch, are seen partially deployed to an open configuration to enable telescope installation. Credits: NASA/Chris Gunn. “This is an exciting time to now see all Webb’s parts finally joined together into a single observatory for the very first time,” says Gregory Robinson, the Webb program director at NASA Headquarters in Washington, D.C. “The engineering team has accomplished a huge step forward and soon we will be able to see incredible new views of our amazing universe.”

Image: Integration teams carefully guide Webb’s suspended telescope section into place above its Spacecraft Element just prior to integration. Credit: NASA/Chris Gunn. The sunshield should allow the telescope, once at the L2 Lagrangian point, to cool down below 50 Kelvin (-223 degrees Celsius) by simply radiating its heat into space. This will allow successful functioning of the near-infrared instruments, which include the Near Infrared Camera (NIRCam), the Near InfraRed Spectrograph (NIRSpec) and the Fine Guidance Sensor / Near Infrared Imager and Slitless Spectrograph (FGS/NIRISS) — all of these work at 39 K (-234°C). The Mid-Infrared Instrument (MIRI) will operate at 7 K (-266 degrees Celsius) using a cryocooler system. Thermal stability will allow proper alignment of the primary mirror segments.

Image: NASA’s James Webb Space Telescope, post-integration, inside Northrop Grumman’s cleanroom facilities in Redondo Beach, California. Credit: NASA/Chris Gunn. With launch scheduled for 2021, extensive environmental and deployment testing will now be undertaken for the fully assembled observatory. All of the telescope’s major components have gone through rounds of environmental tests including launch stress and vibration, but we now have to put the integrated assembly through its paces. As if launch wasn’t stressful enough, we’ll have to sweat out deployment of the sunshield and the 6.5-meter primary mirror, all destined for Earth-Sun L2, which is far beyond the orbit of the Moon. Plenty of suspense ahead as we tune-up for 2021. Getting this expensive bird in place is going to be a nail-biter.

It Looks Like James Webb’s Launch Date is Going to Slip to July 2021

Put “James Webb Telescope launch” into your search engine and you’ll be flooded with links, some reaching back to the ‘scope’s first proposed launch date in 2010. The delayed launch of the space telescope is a running theme in the space community, even though we all know it’s going to be worth the wait. So nobody will be surprised by this latest development in the story of the world’s most anticipated telescope.

The History And Future Of The James Webb Space Telescope

On March 30, 2021, NASA’s James Webb Space Telescope will blast off from the European Space Agency’s European spaceport in Kourou, French Giana on board an Ariane 5 rocket. It’ll fly to the Sun-Earth L2 Lagrange point, a relatively stable spot in space that keeps the glare from the Sun, Earth, and Moon all in a tiny spot in the sky. Then, it’ll unfurl its tennis court-sized sunshade, fold out its gigantic 6.5-meter mirror, and peer out into the distant cosmos. Over the course of the next 10 years, this infrared observatory will help astronomers learn about the earliest moments of the Universe, directly observe the atmospheres of planets orbiting other stars, and peer at newly forming stars and planets. And if you listened to the words I just said with equal parts terror and skepticism, I don’t blame you. James Webb’s path to space has been long and tortuous. And the risks that the mission still faces are very real. Hopefully, the science will be worth it. Hopefully, nothing else goes wrong from now until deployment.

James Webb is Fully Stowed Into its Launch Configuration

We’re inching closer and closer to the James Webb Space Telescope’s (JWST) launch date of March 30th, 2021, (or maybe July 2021.) We never thought we’d get this close, with only a year to go before we send this powerful space telescope on its way. Now the telescope has been put in its launch configuration.

For NASA’s James Webb Space Telescope to fit into an Ariane V rocket for launch, it must fold up. This graphic shows how Webb fits into the rocket fairing with little room to spare. Credits: ArianeSpace.com

Folding the James Webb Space Telescope to Fit Inside the Ariane V Rocket Fairing

This video shows how NASA’s James Webb Space Telescope is designed to fold to a much smaller size in order to fit inside the Ariane V rocket for launch to space. The largest, most complex space observatory ever built, must fold itself to fit within a 17.8-foot (5.4-meter) payload fairing, and survive the rigors of a rocket ride to orbit. After liftoff, the entire observatory will unfold in a carefully choreographed series of steps before beginning to make groundbreaking observations of the cosmos. : Read more Credit: NASA's Goddard Space Flight Center If you liked this video, subscribe to the NASA Goddard YouTube channel: Follow NASA’s Goddard Space Flight Center · Instagram · Twitter NASA GODDARD · Twitter NASA GODDARD PICTURES · Facebook: · Flickr

The History And Future Of The James Webb Space Telescope

On March 30, 2021, NASA’s James Webb Space Telescope will blast off from the European Space Agency’s European spaceport in Kourou, French Giana on board an Ariane 5 rocket. It’ll fly to the Sun-Earth L2 Lagrange point, a relatively stable spot in space that keeps the glare from the Sun, Earth, and Moon all in a tiny spot in the sky. Then, it’ll unfurl its tennis court-sized sunshade, fold out its gigantic 6.5-meter mirror, and peer out into the distant cosmos. Over the course of the next 10 years, this infrared observatory will help astronomers learn about the earliest moments of the Universe, directly observe the atmospheres of planets orbiting other stars, and peer at newly forming stars and planets. And if you listened to the words I just said with equal parts terror and skepticism, I don’t blame you. James Webb’s path to space has been long and tortuous. And the risks that the mission still faces are very real. Hopefully, the science will be worth it. Hopefully, nothing else goes wrong from now until deployment. So today, I want to do a deep dive into James Webb. To talk about the history of the mission, why it exists, how the development went, and where it stands today.

Webb has Arrived Safely at the Launch Site

Whew! A major milestone was achieved today in the James Webb Space Telescope’s journey towards launch. After the telescope successfully arrived in French Guiana yesterday following a secretive 16-day ocean journey (with apparently no pirates in sight), today the telescope took a short road trip over land to the ESA’s spaceport in Kourou. JWST is now at the payload processing facility, where staff will start the process of getting the telescope into the Ariane 5 rocket fairing. Launch is currently scheduled for December 18, 2021 …

Webb NIRSpec multi-object spectrograph

The NIRSpec instrument is the workhorse near-infrared spectrograph on board the James Webb Space Telescope and is provided by ESA. The primary goal of NIRSpec is to enable large spectroscopic surveys of astronomical objects such as stars or distant galaxies. This is made possible by its powerful multi-object spectroscopy mode, which makes use of microshutters. This mode is capable of obtaining spectra of up to nearly 200 objects simultaneously, over a 3.6×3.4 arcminute field of view – the first time this capability has been provided from space. This mode makes for very efficient use of Webb’s valuable observing time. This animation shows the path followed by light from an astronomical object as it travels through the NIRSpec components and onto the detector.

I Could Look at James Webb Unboxing Pictures all Day

The Last Human View of the JAmes Webb Telescope

On Oct. 12th 2021, the James Webb Space Telescope (JWST) arrived safely at Port de Pariacabo in French Guiana after spending 16 days traveling between California and South America. Since then, the observatory was transported from California to French Guiana and brought to a cleanroom in the Guyanese Space Center (GSC). Here, crews “unboxed” the observatory from its protective cargo container in preparation for launch – now targetted for Dec. 18th 2021.

29 Days on the Edge

The greatest origin story of all unfolds with the James Webb Space Telescope. Webb's launch is a pivotal moment that exemplifies the dedication, innovation, and ambition behind NASA and its partners, the European Space Agency (ESA) and Canadian Space Agency (CSA), but it is only the beginning. The 29 days following liftoff will be an exciting but harrowing time. Thousands of parts must work correctly, in sequence, to unfold Webb and put it in its final configuration, all while it flies through the expanse of space alone, to a destination nearly one million miles away. As the largest and most complex telescope ever sent into space, the James Webb Space Telescope is a technological marvel. By necessity, Webb takes on-orbit deployments to the extreme. Each step can be controlled expertly from the ground, giving Webb’s Mission Operations Center full control to circumnavigate any unforeseen issues with deployment.

Webb unboxed in cleanroom at Europe’s Spaceport

After its arrival at Pariacabo harbour in French Guiana on 12 October 2021, the James Webb Space Telescope was transported to Europe’s Spaceport and unboxed in the cleanroom. It is now being prepared for its launch on an Ariane 5 rocket in December. Though the telescope weighs only six tonnes, it is more than 10.5 m high and almost 4.5 m wide when folded. It was shipped in its folded position in a 30 m long container which, with auxiliary equipment, weighed more than 70 tonnes. After arriving in the harbour, the telescope inside its container was towed by a heavy-load tractor unit to the spacecraft processing facility at Europe’s Spaceport. There, Webb’s special shipping container was opened, and the telescope was unboxed inside the facility’s cleanroom and installed on a rollover fixture to raise it vertical. This is how it will stand inside the Ariane 5 fairing. Webb’s launch campaign involves more than 100 specialists. Teams will work separately to prepare the telescope and the launch vehicle until they become one combined team to join the telescope with its rocket for a momentous liftoff. Webb will be the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA is providing the telescope’s launch service using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by @arianespace.

After 10 Days of Dangerous, Careful Work, James Webb has Been Fully Fueled up

On Oct. 12th, 2021, after years of waiting and cost overruns, the James Webb Space Telescope (JWST) finally arrived safely at Europe’s Spaceport in Kourou, French Guiana. The crews began unboxing the next-generation observatory and getting it ready for integration with the Ariane 5 rocket that will take it to space. Then, an “incident” occurred where a clamp band suddenly released, sending vibrations throughout the facility. Once again, the JWST’s launch date was pushed back while crews investigated the source of the problem.

Webb: A new view of the Universe

The world’s next generation cosmic observatory, the James Webb Space Telescope, is due for launch on an Ariane 5 from Europe’s Spaceport in French Guiana in late December. Developed and constructed over more than 30 years, Webb is a remarkable feat of engineering and technology – with the largest astronomical mirror ever flown in space, sophisticated new scientific instruments, and a sunshield the size of a tennis court. Webb is an international partnership between @NASA, ESA and the @Canadian Space Agency and will reveal the Universe in a whole new light. Optimised for infrared wavelengths, its detectors will be able to look back to shortly after the very dawn of time, revealing the formation of the first galaxies, as well as study stars and planets in our own Milky Way.

Webb secured inside Ariane 5 fairing

n Friday 17 December 2021, the Ariane 5 rocket fairing was closed around the James Webb Space Telescope. This protective fairing, or ‘nose cone’, will shield the telescope during liftoff and its journey through the atmosphere on 24 December. Earlier, Webb was placed on top of Ariane 5 and a protective ‘shower curtain’ was put up to avoid any contamination. On the day of encapsulation in the fairing, a protective cover on top of Webb was removed and the fairing was lowered down over the observatory and locked in place for liftoff. This was a particularly delicate operation, assisted by a laser guiding system, because the margins between the folded up observatory (4.5 m wide) and the rocket fairing (5.4 m wide) are small. The fairing is equipped with specialised environmental controls that keep the observatory in a perfectly controlled temperature and humidity range during its final few days on Earth. Now that Webb has been securely attached to its Ariane 5 launch vehicle, and enclosed within its protective fairing, mechanical operations involving the observatory at its launch site in French Guiana have formally concluded. Final electrical and software configurations will occur on the launch pad during the final hours before liftoff. Webb will switch to internal battery power roughly 20 minutes prior to liftoff, and within 15 minutes prior the observatory and its launch vehicle will both be fully cleared for flight. Ariane 5’s rollout to the launch pad is scheduled to begin Wednesday 22 December 2021, and this is where final health checks and preparations for liftoff will occur. Webb will be the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA is providing the telescope’s launch service using the Ariane 5 launch vehicle.

JWST’s Precise Launch and Near-Perfect Course Corrections Mean Fuel Savings.
And That Means a Longer Mission

after a detailed analysis of where the James Webb Space Telescope is now (Dec. 29, 2021) and how it got there, NASA determined the observatory should have enough propellant to operate in space for significantly more than 10 years in space. Webb’s mission lifetime was designed to be at least 5-1/2 years, and mission engineers and scientists were hoping for closer to 10 years.

Webb’s orbit is around L2—a point of gravitational balance on the other side of Earth from the Sun—but it does not reside exactly at the L2 point. Right at that point, Earth’s shadowing of the Sun would be large enough to greatly reduce the amount of power available for Webb’s solar arrays, without greatly simplifying the cooling challenges. In addition, when Webb’s communication antennas point at Earth to receive commands, they would be blinded by the huge radio emission of the Sun in the same direction. Instead, as the diagram indicates, Webb operates in a very loose orbit (many hundreds of thousands of km in diameter) around L2, in constant sunlight and with clean communications with the ground stations.

see the wikipedia article on lagrange points below

You’re hot and you’re cold… 🎵 The JWST is split into a “hot side” and “cold side” by its sunshield. The sunshield will always be facing the Sun to block out heat and light, as Webb's mirrors need to stay extremely cold to observe faint heat signals in the universe!

    Star twinkles 18 times in new James Webb Space Telescope image

    The James Webb Space Telescope finished the first major stage in its long process of aligning the observatory's 18-segmented primary mirror. A single star that the observatory looked at was deliberately rendered 18 times into a hexagonal shape. Eventually, those 18 images will perfectly align into a single, sharp focus, but the interim result portrays a star repeated perfectly in a hexagonal pattern reminiscent of a stunning celestial snowflake. "The resulting image shows that the team has moved each of Webb’s 18 primary mirror segments to bring 18 unfocused copies of a single star into a planned hexagonal formation," NASA officials wrote in a blog post Friday (Feb. 18, 2022).


    Webb turns those 18 separate star images into a single unified star. Next comes even better focus.

    It’s coming together! Engineers for the James Webb Space Telescope have now completed two more phases of the seven-step, three-month-long mirror alignment process. This week, the team made more adjustments to the mirror segments along with updating the alignment of its secondary mirror. These refinements allowed for all 18 mirror segments to work together — for the first time — to produce one unified image.

    NASA’s Webb Reaches Alignment Milestone, Optics Working Successfully

    Following the completion of critical mirror alignment steps, the James Webb Space Telescope team has great confidence that the observatory’s optical performance will meet or exceed the science goals it was built to achieve. On March 11, 2022 the Webb team completed the stage of alignment known as “fine phasing” – and at this key stage in the commissioning of Webb’s Optical Telescope Element, every optical parameter that has been checked and tested is performing at, or above, expectations. The team found no critical issues and no measurable contamination or blockages to Webb’s optical path. The observatory is able to successfully gather light from distant objects and deliver it to its instruments without issue. Although there are months to go before Webb ultimately delivers its new view of the cosmos, achieving this milestone means the team is confident that Webb’s first-of-its-kind optical system is working as well as possible.

    Prepare Yourself: New Engineering Images from JWST Will Blow Your Mind

    If the phrase “My god, it’s full of stars” was ever appropriate, it’s today, because of these new images from the James Webb Space Telescope. These are ‘just’ engineering images, mind you, but they are incredible. The number of stars and galaxies visible in each image is just remarkable, not to mention the crisp clarity in the fields of view.

    The Webb Telescope Completes Alignment Phase

    It is official, alignment of NASA’s James Webb Space Telescope is now complete. The alignment of the telescope across all of Webb’s instruments can be seen in a series of images that captures the observatory’s full field of view. Featured in this video are engineering images demonstrating the sharp focus of each instrument. For this test, Webb pointed at part of the Large Magellanic Cloud, a small satellite galaxy of the Milky Way, providing a dense field of hundreds of thousands of stars across all the observatory’s sensors. The sizes and positions of the images shown depict the relative arrangement of each of Webb’s instruments in the telescope’s focal plane, each pointing at a slightly offset part of the sky relative to one another. Webb’s three imaging instruments are NIRCam (images shown here at a wavelength of 2 microns), NIRISS (image shown here at 1.5 microns), and MIRI (shown at 7.7 microns, a longer wavelength revealing emission from interstellar clouds as well as starlight). NIRSpec is a spectrograph rather than imager but can take images, such as the 1.1 micron image shown here, for calibrations and target acquisition. The dark regions visible in parts of the NIRSpec data are due to structures of its microshutter array, which has several hundred thousand controllable shutters that can be opened or shut to select which light is sent into the spectrograph. Lastly, Webb’s Fine Guidance Sensor tracks guide stars to point the observatory accurately and precisely; its two sensors are not generally used for scientific imaging but can take calibration images such as those shown here. This image data is used not just to assess image sharpness but also to precisely measure and calibrate subtle image distortions and alignments between the instrument sensors as part of Webb’s overall instrument calibration process.

    Webb is Almost Ready. There’s One Last Thing To Do

    MAY 9, 2022 BY NANCY ATKINSON The James Webb Space Telescope is now in the final phase of commissioning as it readies for science observations. Of the more than 1,000 milestones the observatory has needed to reach since launch to become fully operational, the team said today they are down to about two hundred activities to go. But those 200 are all part of the final phase of commissioning the instruments.

    JWST Sees the Most Distant Galaxy Ever, Just 300 Million Years After the Big Bang

    By now, almost everyone has seen the first-release images from JWST and marveled at these amazing views of the infrared universe the telescope was launched to explore. The view of SMACS 0723 seen above illustrates the promise JWST holds.
