Something new:

Measuring over 200,000 light-years in diameter, roughly twice as large as the Milky Way, NGC 1365 is noted for the way its wide arms extend from its central bar to give it a Z-like appearance. The galaxy was selected for observations by JWST because of its iconic nature and how much of its interior structure is obscured by dust. In particular, its second bar is more prominent in infrared images, and previous instruments (like the Hubble and Spitzer space telescopes) have been limited in terms of what they could visualize.

CAPE CANAVERAL, Fla. (AP) — The world’s newest and biggest space telescope is showing Jupiter as never before, auroras and all. 

Scientists released the shots Monday of the solar system’s biggest planet.

The James Webb Space Telescope took the photos in July, capturing unprecedented views of Jupiter’s northern and southern lights, and swirling polar haze. Jupiter’s Great Red Spot, a storm big enough to swallow Earth, stands out brightly alongside countless smaller storms.

One wide-field picture is particularly dramatic, showing the faint rings around the planet, as well as two tiny moons against a glittering background of galaxies.

NASA’s James Webb Space Telescope has captured the first clear evidence for carbon dioxide in the atmosphere of a planet outside the solar system. This observation of a gas giant planet orbiting a Sun-like star 700 light-years away provides important insights into the composition and formation of the planet. The finding, which is accepted for publication in Nature, offers evidence that in the future Webb may be able to detect and measure carbon dioxide in the thinner atmospheres of smaller, rocky planets. 

WASP-39 b is a hot gas giant with a mass roughly one-quarter that of Jupiter (about the same as Saturn) and a diameter 1.3 times greater than Jupiter. Its extreme puffiness is related in part to its high temperature (about 1,600 degrees Fahrenheit or 900 degrees Celsius). Unlike the cooler, more compact gas giants in our solar system, WASP-39 b orbits very close to its star – only about one-eighth the distance between the Sun and Mercury – completing one circuit in just over four Earth-days. The planet’s discovery, reported in 2011, was made based on ground-based detections of the subtle, periodic dimming of light from its host star as the planet transits, or passes in front of the star.

Scientists have been making a lot of intriguing discoveries with the James Webb space telescope. Webb’s first images gave us a detailed look at the early universe, and we’ve even detected carbon dioxide on an exoplanet with it. Some speculate that a mysterious energy source picked up by James Webb could entirely change things for renewable energy. Others, however, feel it could just be a normal phenomenon

NASA’s James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet’s rings in more than 30 years, but its cameras reveal the ice giant in a whole new light.

Most striking in Webb’s new image is the crisp view of the planet’s rings – some of which have not been detected since NASA’s Voyager 2 became the first spacecraft to observe Neptune during its flyby in 1989. In addition to several bright, narrow rings, the Webb image clearly shows Neptune’s fainter dust bands.

“It has been three decades since we last saw these faint, dusty rings, and this is the first time we’ve seen them in the infrared,” notes Heidi Hammel, a Neptune system expert and interdisciplinary scientist for Webb. Webb’s extremely stable and precise image quality permits these very faint rings to be detected so close to Neptune.

November 17, 2022

The state of the art James Webb Space Telescope, operated by NASA, has uncovered a hitherto mostly unexplored "undiscovered territory" of early galaxies that is surprisingly abundant. The universe being revealed by Webb is incredibly rich, and the first galaxies that formed seem very different from the mature galaxies we see around us now. Two extremely brilliant galaxies were discovered by researchers between 350 and 450 million years after the big bang. Astronomers find their great brightness perplexing. Young galaxies are converting gas into stars at a very fast rate. They are much smaller than Milky Way galaxy in size, but are compressed into spherical or disk shapes. Just 100 million years after the big bang, which occurred 13.8 billion years ago, stellar birth may have begun.

The distances to these far-off galaxies should be confirmed by additional spectroscopic measurements made with the Webb space telescope, which will also provide information on the rate of star formation and the elemental abundances in the early stars.

After only a few days of official science operations, NASA's James Webb Space Telescope allowed scientists to observe early galaxies that had previously eluded all previous telescopes. Researchers discovered two extraordinarily brilliant galaxies in the GLASS-JWST photos after only four days of processing. Future spectroscopic observations with Webb will help corroborate that these galaxies existed between 450 and 350 million years after the big bang (with a redshift of roughly 10.5 and 12.5, respectively).

These two galaxies' current Webb distance estimates are based on analyzing their infrared hues. These cosmic yardstick readings will eventually be independently verified by subsequent spectroscopy measurements that demonstrate how light has been stretched in the expanding universe.

NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, it is less mysterious with new findings from NASA’s James Webb Space Telescope.  

NCG 346 is located in the Small Magellanic Cloud (SMC), a dwarf galaxy close to our Milky Way. The SMC contains lower concentrations of elements heavier than hydrogen or helium, which astronomers call metals, compared to the Milky Way. Since dust grains in space are composed mostly of metals, scientists expected there would be low amounts of dust, and that it would be hard to detect. New data from Webb reveals the opposite. 
 

Astronomers probed this region because the conditions and amount of metals within the SMC resemble those seen in galaxies billions of years ago, during an era in the universe known as “cosmic noon,” when star formation was at its peak. Some 2 to 3 billion years after the big bang, galaxies were forming stars at a furious rate. The fireworks of star formation happening then still shape the galaxies we see around us today.  

“A galaxy during cosmic noon wouldn’t have one NGC 346 like the Small Magellanic Cloud does; it would have thousands” of star-forming regions like this one, said Margaret Meixner, an astronomer at the Universities Space Research Association and principal investigator of the research team. “But even if NGC 346 is now the one and only massive cluster furiously forming stars in its galaxy, it offers us a great opportunity to probe conditions that were in place at cosmic noon.”

A few new updates:

Astronomers have revealed the latest deep field image from NASA’s James Webb Space Telescope, featuring never-before-seen details in a region of space known as Pandora’s Cluster (Abell 2744). Webb’s view displays three clusters of galaxies – already massive – coming together to form a megacluster. The combined mass of the galaxy clusters creates a powerful gravitational lens, a natural magnification effect of gravity, allowing much more distant galaxies in the early universe to be observed by using the cluster like a magnifying glass.

Only Pandora’s central core has previously been studied in detail by NASA’s Hubble Space Telescope. By combining Webb’s powerful infrared instruments with a broad mosaic view of the region’s multiple areas of lensing, astronomers aimed to achieve a balance of breadth and depth that will open up a new frontier in the study of cosmology and galaxy evolution.

“The ancient myth of Pandora is about human curiosity and discoveries that delineate the past from the future, which I think is a fitting connection to the new realms of the universe Webb is opening up, including this deep-field image of Pandora’s Cluster,” said astronomer Rachel Bezanson of the University of Pittsburgh in Pennsylvania, co-principal investigator on the “Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization” (UNCOVER) program to study the region.

“When the images of Pandora’s Cluster first came in from Webb, we were honestly a little star struck,” said Bezanson. “There was so much detail in the foreground cluster and so many distant lensed galaxies, I found myself getting lost in the image. Webb exceeded our expectations.” The new view of Pandora’s Cluster stitches four Webb snapshots together into one panoramic image, displaying roughly 50,000 sources of near-infrared light.

Researchers using NASA’s James Webb Space Telescope are getting their first look at star formation, gas, and dust in nearby galaxies with unprecedented resolution at infrared wavelengths. The data has enabled an initial collection of 21 research papers which provide new insight into how some of the smallest-scale processes in our universe – the beginnings of star formation – impact the evolution of the largest objects in our cosmos: galaxies.

An international team of astronomers using NASA’s James Webb Space Telescope has obtained an in-depth inventory of the deepest, coldest ices measured to date in a molecular cloud. In addition to simple ices like water, the team was able to identify frozen forms of a wide range of molecules, from carbonyl sulfide, ammonia, and methane, to the simplest complex organic molecule, methanol. This is the most comprehensive census to date of the icy ingredients available to make future generations of stars and planets, before they are heated during the formation of young stars.

This image from the telescope’s Near-Infrared Camera (NIRCam) features the central region of the Chamaeleon I dark molecular cloud, which resides 630 light-years away. The cold, wispy cloud material (blue, center) is illuminated in the infrared by the glow of the young, outflowing protostar Ced 110 IRS 4 (orange, upper left). The light from numerous background stars, seen as orange dots behind the cloud, can be used to detect ices in the cloud, which absorb the starlight passing through them.

NGC 346, shown here in this image from NASA’s James Webb Space Telescope Near-Infrared Camera (NIRCam), is a dynamic star cluster that lies within a nebula 200,000 light years away. Webb reveals the presence of many more building blocks than previously expected, not only for stars, but also planets, in the form of clouds packed with dust and hydrogen. The plumes and arcs of gas in this image contains two types of hydrogen. The pink gas represents energized hydrogen, which is typically as hot as around 10,000 °C (approximately 18,000 °F) or more, while the more orange gas represents dense, molecular hydrogen, which is much colder at around -200 °C or less (approximately -300 °F), and associated dust. The colder gas provides an excellent environment for stars to form, and, as they do, they change the environment around them. The effect of this is seen in the various ridges throughout, which are created as the light of these young stars breaks down the dense clouds. The many pillars of glowing gas show the effects of this stellar erosion throughout the region. In this image blue was assigned to the wavelength of 2.0 microns (F200W), green was assigned to 2.77 microns (F277W), orange was assigned to 3.35 microns (F335M), and red was assigned to 4.44 microns (F444W).

Nobody expected them. They were not supposed to be there. And now, nobody can explain how they had formed. 

Galaxies nearly as massive as the Milky Way and full of mature red stars seem to be dispersed in deep field images obtained by the James Webb Space Telescope (Webb or JWST)  during its early observation campaign, and they are giving astronomers a headache. 

These galaxies, described in a new study based on Webb's  first data release, are so far away that they appear only as tiny reddish dots to the powerful telescope. By analyzing the light emitted by these galaxies, astronomers established that they were viewing them in our universe's infancy only 500 to 700 million years after the Big Bang.

NASA’s James Webb Space Telescope has detected churning clouds of dust on a distant planet that orbits two stars. 

Known as VHS 1256 b, the exoplanet is about 40 light-years away from Earth and orbits at a long distance from its stars, ideal conditions for fine grained observation with Webb, according to Brittany Miles, a fellow at the University of Arizona and coauthor of the new research.

The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius.

This Webb image features a special galaxy that appears three times. Why? There's a galaxy cluster here whose mass and gravity are so great that time and space around it gets warped. This magnifies, multiplies, and distorts distant galaxies behind the cluster, such as the one highlighted in the three white boxes. The effect is known as gravitational lensing.

The tripled galaxy contains an exploding star, part of a Type Ia (pronounced One-A) supernova. These supernovae have a standard brightness, but this particular galaxy’s supernova has been magnified by the cluster to look closer and brighter. By comparing the standard brightness with how bright this supernova appears to be, we can calculate the true distance of its galaxy.
