FGS/NIRISS a Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph , led by the Canadian Space Agency under project scientist John Hutchings (Herzberg Astronomy and Astrophysics Research Centre, National Research Council), is used to stabilize the line-of-sight of the observatory during science observations. NIRSpec (Near InfraRed Spectrograph) will also perform spectroscopy over the same wavelength range. NIRCam (Near InfraRed Camera) is an infrared imager which will have a spectral coverage ranging from the edge of the visible (0.6 μm) through to the near infrared (5 μm). MIRI (Mid-InfraRed Instrument) will measure the mid-to-long-infrared wavelength range from 5 to 27 μm. It contains both a mid-infrared camera and an imaging spectrometer.

JWST also has a starlight-blocking coronagraphs like Soho but for observation of faint targets such as extrasolar planets and circumstellar disks very close to bright stars, it probably can hook up with Hubble and other Ground Based telescopes to get confirmation on its results.

Now, the commissioning team is entering a new phase. Soon, JWST will enter its first year of science observations — what’s known as Cycle 1 science — which is jam-packed with plans to target exoplanets, galaxies, exotic stars, and more. Those working with JWST’s instruments will move into a support role for the astronomers who have time with the observatory in the first year. Those scientists will inevitably have questions about how to use this powerful new observatory or how to interpret their results, and the instrument teams at NASA and STScI will need to be on hand to provide answers. “The observatory will be used in ways that we haven’t completely experienced yet,” says Friedman. “So we’ll be watching that carefully.”

Lots and lots of images and data coming out.

Maybe the other press gathering can be forgotten. However it seems JWST has made some great discovery

A light curve from Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) shows the change in brightness of light from the WASP-96 star system over time as the planet transits the star.
https://webbtelescope.org/contents/medi … 40c26f4c97

Although full analysis of the spectrum will take additional time, it is possible to draw a number of preliminary conclusions. The labeled peaks in the spectrum indicate the presence of water vapor. The height of the water peaks, which is less than expected based on previous observations, is evidence for the presence of clouds that suppress the water vapor features. The gradual downward slope of the left side of the spectrum (shorter wavelengths) is indicative of possible haze. The height of the peaks along with other characteristics of the spectrum is used to calculate an atmospheric temperature of about 1350°F (725°C).
This is the most detailed infrared exoplanet transmission spectrum ever collected, the first transmission spectrum that includes wavelengths longer than 1.6 microns with such high resolution and accuracy, and the first to cover the entire wavelength range from 0.6 microns (visible red light) to 2.8 microns (near-infrared) in a single shot. The speed with which researchers have been able to make confident interpretations of the spectrum is further testament to the quality of the data.
The observation was made using NIRISS’s Single-Object Slitless Spectroscopy (SOSS) mode, which involves capturing the spectrum of a single bright object, like the star WASP-96, in a field of view

Exoplanet WASP-96 b (NIRISS Transit Light Curve)

To capture these data, Webb stared at the WASP-96 star system for 6 hours 23 minutes, beginning about 2½ hours before the transit and ending about 1½ hours after the transit was complete. The transit itself lasted for just under 2½ hours. The curve includes a total of 280 individual brightness measurements – one every 1.4 minutes.
Because the observation was made using a spectrograph, which spreads the light out into hundreds of individual wavelengths, each of the 280 points on the graph represents the combined brightness of thousands of wavelengths of infrared light.
The actual dimming caused by the planet is extremely small: The difference between the brightest and dimmest points is less than 1.5 percent. NIRISS is ideally suited for this observation because it has the ability to observe relatively bright targets over time, along with the sensitivity needed to measure such small differences in brightness: In this observation, the instrument was able to measure differences in brightness as small as 0.02 percent.
Although the presence, size, mass, and orbit of the planet had already been determined based on previous transit observations, this transit light curve can be used to confirm and refine existing measurements, such as the planet’s diameter, the timing of the transit, and the planet’s orbital properties.
WASP-96 b is a hot gas giant exoplanet that orbits a Sun-like star roughly 1,150 light-years away, in the constellation Phoenix. The planet orbits extremely close to its star (less than 1/20th the distance between Earth and the Sun) and completes one orbit in less than 3½ Earth-days. The planet’s discovery, from ground-based observations, was announced in 2014.

Webb Sheds Light on Galaxy Evolution, Black Holes
https://esawebb.org/news/weic2208/

Located in the constellation Pegasus, Stephan’s Quintet was discovered by the French astronomer Édouard Stephan in 1877.

Stephan’s Quintet, a visual grouping of five galaxies, is best known for being prominently featured in the holiday classic film, “It’s a Wonderful Life.”

Webb is the largest, most powerful telescope ever launched into space.

https://webbtelescope.org/contents/medi … M13FWQ881E

Stephan’s Quintet is a visual grouping of five galaxies located in the constellation Pegasus. Together, they are also known as the Hickson Compact Group 92 (HCG 92). Although called a “quintet,” only four of the galaxies are truly close together and caught up in a cosmic dance. The fifth and leftmost galaxy, called NGC 7320, is well in the foreground compared with the other four.

Tight groups like this may have been more common in the early universe when their superheated, infalling material may have fueled very energetic black holes called quasars. Even today, the topmost galaxy in the group – NGC 7319 – harbors an active galactic nucleus, a supermassive black hole 24 million times the mass of the Sun. It is actively pulling in material and puts out light energy equivalent to 40 billion Suns.

Some of the key emission lines seen by NIRSpec are shown in this image and represent different phases of gas. Atomic hydrogen, in blue and yellow, allows scientists to discover the structure of the outflow. Iron ions, in teal, trace the places where the hot gas is located. Molecular hydrogen, in red, is very cold and dense, and traces both outflowing gas and the reservoir of fuel for the black hole. The bright, active nucleus itself has been removed from these images to better show the structure of the surrounding gas.
By using NIRSpec, scientists have gained unprecedented information about the black hole and its outflow. Studying these relatively nearby galaxies helps scientists better understand galaxy evolution in the much more distant universe.

Webb reveals steamy atmosphere of exoplanet WASP-96 b, capturing the distinct signature of water along with evidence for clouds & haze — the most detailed measurements of this kind to date.

Behind the curtain of dust and gas in these “Cosmic Cliffs” are previously hidden baby stars, now uncovered by Webb. We know — this is a show-stopper. Just take a second to admire the Carina Nebula in all its glory: nasa.gov/webbfirstimages/
Webb’s new view gives us a rare peek into stars in their earliest, rapid stages of formation. For an individual star, this period only lasts about 50,000 to 100,000 years.

Two cameras are better than one, as seen in this combined view from Webb’s NIRCam & MIRI! In the near-infrared, we see hundreds of stars and background galaxies. Meanwhile, the mid-infrared shows us dusty planet-forming disks (in red and pink) around young stars.

The dawn of a new era in astronomy has begun as the world gets its first look at the full capabilities of the NASA/ESA/CSA James Webb Space Telescope. The telescope’s first full-colour images & spectroscopic data were released today.

In the James Webb Space Telescope’s image of Stephan’s Quintet, we see 5 galaxies, 4 of which interact. (The left galaxy is actually in the foreground!) These colliding galaxies are pulling and stretching each other in a gravitational dance. Webb will revolutionize our knowledge of star formation and gas interactions within: nasa.gov/webbfirstimages/
Here’s Stephan’s Quintet as taken by Webb’s MIRI instrument. In the mid-infrared, Webb pierces through dust, giving new insight into how interactions like these may have driven galaxy evolution in the early universe.

This image contains one more MIRI filter than was used in the NIRCam-MIRI composite picture. The image processing specialists at the Space Telescope Science Institute in Baltimore opted to use all three MIRI filters and the colors red, green and blue to most clearly differentiate the galaxy features from each other and the shock waves between the galaxies. In this image, red denotes dusty, star-forming regions, as well as extremely distant, early galaxies and galaxies enshrouded in thick dust. Blue point sources show stars or star clusters without dust. Diffuse areas of blue indicate dust that has a significant amount of large hydrocarbon molecules. For small background galaxies scattered throughout the image, the green and yellow colors represent more distant, earlier galaxies that are rich in these hydro carbons as well.

Atmospheric compositions are fundamental to our un- derstanding of the nature and origins of planets. For
example, the enhanced metallicities of the primary atmospheres of giant planets relative to their host stars’
abundances are a tracer of these planets’ formation histories (e.g., Owen et al. 1999). On the other hand, the
compositions of the secondary atmospheres of terrestrial planets are a record of atmospheric evolution due to
escape, geophysical, and, perhaps, biological processes
(e.g., Meadows & Seager 2010). For all planets, measuring the atmospheric composition is crucial to assessing
and understanding planetary climate, including habit-
ability.

Observing a bright planet and its satellites and rings was expected to be challenging, due to scattered light that may affect the science instrument employed, but also the fine guidance sensor must track guide stars
Page 8 near the bright planet. Therefore, commissioning included tests of moving target tracking with NIRCam, where Jupiter was incrementally moved from the NIRCam field of view (FOV) to the FGS-2 FOV. See
Figure 1. These observations verified the expectation that guide star acquisition works successfully as
long as Jupiter is at least 140” away from the FGS, consistent with pre-flight modeling.
The other SIs were also tested for efficiency with nearby scattered light, also using the Jupiter system. Preliminary results have measured scattered light contamination on the detectors for all instruments when the planet was not in the primary FOV, which will need to be considered for planning nearby satellite
observation

NIRCam narrow-band imaging of Jupiter, moons, and ring. PID 1022 demonstrated that JWST can track moving targets even when there is scattered light from a bright Jovian planet. At left is a NIRCam short-wavelength image in filter F212N (2.12 μm); at right is a NIRCam long-wavelength image
in filter F323N (3.23 μm). The exposure time was 75 s. The Jovian moons Europa, Thebe, and Metis are
labeled. The shadow of Europa is also visible, just to the left of the Great Red Spot. The stretch is fairly harsh to bring out the faint moons as well as Jupiter’s ring.

JWST is the product of the efforts of approximately 20,000 people in an international team.
Commissioning JWST and characterizing science performance is the result of tremendous effort by the
JWST commissioning team over the last six months. The achieved performance is the result of efforts
over the many years leading to launch by team members across much of the globe. Given the measured
performance described in this document, the JWST mission enters Cycle 1 having demonstrated that the
observatory exceeds its demanding pre-launch performance expectations. With revolutionary capabilities,
JWST has begun the first of many years of scientific discover

Hubble and Webb

two arcs are the same Galaxy
https://www.flickr.com/photos/nasawebbt … 210554682/

By quickly examining the image at left by eye, it becomes clearer that one arc may be made up of two similar-looking galaxies. Their bright central regions match, despite their stretched appearances. These may be lensed galaxies – one galaxy that is mirrored in a second location. Are they the same? Researchers can’t be sure from the image alone – more data are needed to confirm a match.

Scientists do this by gathering spectra, which spread light out so they can fully examine an object’s makeup. Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS), which gathers spectra of every object in any field it observes, was pointed at the galaxy cluster to gather more detail. A segment of the NIRISS grism image (an instrument that has a grating, or stair steps, on a prism), at center, shows how ionized oxygen and atomic hydrogen emission lines are distributed along the arc.

Next, the spectra from each of these two galaxies were plotted as graphs, shown at right, to reveal their compositions. The graphs, known as spectra, match, which indicates that these arcs are mirror images of the same galaxy. Webb’s spectra from NIRISS also quickly proved that light from both galaxies was emitted 9.3 billion years ago, further confirming they are one and the same.

https://webbtelescope.org/contents/medi … WP5ESGSFXF

Using IFUs, scientists can measure spatial structures, determine the velocity of those structures, and get a full range of spectral data. Much like medical magnetic resonance imaging (MRI), the IFUs allow scientists to “slice and dice” the information into many images for detailed study.
MIRI’s MRS pierced through the shroud of dust near the active galactic nucleus to measure the bright emission from nearby hot gas that is being ionized by powerful winds and radiation from the black hole. The instrument saw the gas near the supermassive black hole at a level of detail never seen before, and it was able to determine its composition.
When a supermassive black hole feeds, some of the infalling material becomes very hot and is pushed away from the black hole in the form of winds and jets. MIRI probed many different regions, including the black hole’s outflowing wind – indicated by the smaller circle – and the area immediately around the black hole itself – indicated by the larger circle. It showed that the black hole is enshrouded in silicate dust similar to beach sand, but with much smaller grains.

The top spectrum, from the black hole’s outflow, shows a region filled with hot, ionized gases, including iron, argon, neon, sulfur and oxygen as denoted by the peaks at given wavelengths. The presence of multiple emission lines from the same element with different degrees of ionization is valuable for understanding the properties and origins of the outflow.

The bottom spectrum reveals that the supermassive black hole has a reservoir of colder, denser gas with large quantities of molecular hydrogen and silicate dust that absorb the light from the central regions of the galaxy.

Can you find the Blackhole distorting the space image?

Light from Galaxies bend around a yet unseen undetected blackhole, we can see a much stronger visual display of bending spacetime curvature, gravitational bending light around a massive object from a distant source. Most of the gravitational lenses found in past images were fluke discoveries, in the past they have been discovered accidentally but JWST can follow up on discovery already known by space telescopes like Hubble. Newly found gravitational lenses can also serve as light magnification tools that help astronomers to look at even more distant galaxies he gravity lenses thus acting as a natural telescope

Hubble is great but is it fair to compare a totally different machine JWST to Hubble, JWST goes beyond visual and is a multipurpose IR observatory.

I bought some old Cosmology books a while back but I never really read them like I would read other science books, one time I wasn't a big fan of Fringe ideas or Cosmology I guess Hubble and things reported in news like Cern changed that but one time I thought all stuff about future tech and these futurist sciences were mostly in the far distant future or speculation. At one time I wasn't a fan of fringe Cosmology stuff I thought it was more philosophy than true 'science' but I think different now and a lot has been proven true. What is amazing in the difference between Stephan’s Quintet and SMACS-0723 from JWST is you might also expect Stephan’s Quintet to have Supermassive Blackholes at their center and to also show effects of Gravitational Lens but there is none or none that I can clearly see. I can see the collisions, the spiral arms thrown off, regions of star burst forming in the Quintet but it is only SMACS-0723 that shows this amazing lenses feature.
