Dazzling first images from James Webb Space Telescope (NOVA Next)

Images of five targets showcase the most distant objects ever observed in outer space.

In the mid-infrared image on the right, we can see the white dwarf more clearly, surrounded by dust, a view made possible because of the power of JWST’s instruments. The gravitational interactions pull broad trails of gas and dust away from the galaxies, and Webb’s MIRI (Mid-Infrared Instrument) shows huge shockwaves as one of the galaxies, NGC 7318 B, slams through the cluster. This massive landscape of cosmic mountains and valleys in the Carina Nebula is known as the “Cosmic Cliffs.” Here the bubbles, cavities, and jets of newborn stars are made visible through the dust in a way that was impossible when the Hubble Space Telescope imaged this region of intense star formation. This pair of images of the Southern Ring Nebula shows two powerful perspectives on the same binary star system, a white dwarf and its younger counterpart. The youngest stars appear as red dots in the darker areas of the dust cloud; others are emitting ‘protostellar’ jets typical of early star birth. The space telescope, a project 30 years in the making, launched in December 2021 and arrived at its destination point in January. After a lengthy “unfolding” process, JWST turned its 21-foot mirror on the stars.

Through direct comparison with images from Hubble, you can start to see the exquisite detail and clarity Webb provides.

And the mid-infrared reveals light from a supermassive black hole in the centre of the top galaxy. The detail of the dust distribution and the tug-of-war taking place between the galaxies leaps out from the image. What also stands out is the vast sea of distant galaxies in the background. And that’s just the beginning. The mid-infared also highlights the dust being formed in the expanding gas. The five galaxies are in close proximity. Located some 1120 light-years away, this planet weighs in at about half the mass of Jupiter. This happens at a speed of about 15 kilometres per second, sending out rings of gas and dust. You’ll immediately notice the many elongates arcs, representing background galaxies which have been “gravitationally lensed” as a result of the cluster’s mass. Today we saw the release of the first batch of images taken by the James Webb Space Telescope. This is something we have both been waiting on for nearly 25 years. It seems the bar has been raised once again, and Webb is set to herald a new age for astronomy and space research. Now, with the long-awaited first images in our hands, let’s take a look at what they show.

What's next for the James Webb Space Telescope? (Space.com)

Astronomers around the world anxiously await their opportunity to pore over the data gathered by the James Webb Space Telescope.

People are going to use lots of different techniques to get as much science as they can out of the data." "And so they get priority, because we want the community to have as much data available, in particular by the time they get to propose again." "Those data will be released to the principal investigators of those programs in the next day or two, and some of them are public," he said. Making that data available to the public as the program continues will be key to unlocking new discoveries, he noted. The telescope contains four different instruments that can combine to collect data in 17 different modes. "The first year of science observations have already begun.

These 5 Photos From the James Webb Space Telescope Are Mind ... (TIME)

Yesterday's big reveal of pictures from the James Webb Space Telescope are not just dazzling; they also pack a lot of science.

A scientific graph is not nearly as striking as a cosmic photo, but in this case the graph has a story to tell. Webb has the capability not just to image the Southern Ring Nebula, but to analyze its chemistry, understanding more about how stars shed their matter as they die. Webb captured an image of this pair of elderly stars orbiting each other approximately 2,500 light years from Earth. As the stars enter the end of their lives, they give off gas and dust that form the nebulae, or clouds, that surround them. Clusters of young stars appear as bright sparkles in the image and thousands of more-distant galaxies are visible in the background. Webb captured the greatest image ever taken of Stephan’s Quintet, a cluster of five galaxies, first seen by astronomers in 1877. The formations that look like cliffs are vast peaks of dust and gas, some as tall as seven light years.

Who was James Webb? Why do scientists want to rename the ... (NBC News)

James Webb was undersecretary of state during the Truman administration when the federal government systematically purged its ranks of LGBTQ employees.

The petition has been signed by more than 1,700 people, most of whom work in astronomy or “a related field.” It calls on NASA to instead “bestow this honor on someone whose legacy befits a telescope whose data will be used in discoveries that will inspire future generations of astronomers.” Webb ran NASA, then a fledgling space agency, from 1961 to 1968, playing a major role in the Apollo program. NASA has billed the mission as an “Apollo moment,” with the potential to answer probing questions at the frontier of space discovery, including about life on other planets.

What We Learned From the Webb Telescope's First Images (The New York Times)

NASA on Tuesday released five images from the early work of the James Webb Space Telescope. The pictures highlighted the great potential of the telescope to ...

NASA officials said the distortion was barely noticeable and the performance of Webb still exceeds all of its requirements. For a spacecraft like the James Webb Space Telescope, it was inevitable that pieces of cosmic dust would hit its mirrors. But when astronomers who operate the Webb telescope at the Space Science Telescope Institute in Baltimore saw it, they gasped and applauded. Astronomers theorize that the most distant, earliest stars may be unlike the stars we see today. The light from those galaxies, magnified into visibility by the gravitational field of the cluster, originated more than 13 billion years ago. Some 13 projects have been deemed Early Release Science Programs, chosen to jump start the Webb era. Below are some of the things we have learned so far. NASA’s experience with the Hubble Space Telescope sending back blurry images showed that advanced scientific instruments sometimes did not work as intended. “And it works better than we thought.” The scientific research is already underway. There is a lot more universe out there to see than there was before the telescope launched, and there is so much more to explain. NASA on Tuesday released five images from the early work of the James Webb Space Telescope. The pictures highlighted the great potential of the telescope to plumb the secrets of deep space.

Those Beautiful James Webb Space Telescope Images Are Just the ... (Slate Magazine)

Hannah Docter-Loeb: How is JWST different from previous telescopes? It's about a hundred times more sensitive than the Hubble Space Telescope. It's got a much ...

The level of detail and the number of objects and just the clarity are really, really striking and very moving in a way. JWST took a couple of images of a piece of this nebula with different bands of infrared light, and looking at this picture is just really moving, because you can see these tendrils of dust and gas, and you can see the tiny pinpricks of new stars forming inside these clouds of gas. Hopefully, we’ll get to learn about the atmospheres of planets around other stars, maybe planets that are more like Earth. It’s possible that we’ll be able to see spectra of other planets, which could tell us something about the atmospheres of planets, maybe similar to Earth, orbiting other stars. I think that, if we take that seriously, then we need also to take this seriously, the concerns of people who are feeling excluded and disrespected by the decisions that NASA made around this project. The main thing you see when you look at that image is that it’s just full of galaxies. I’ve been trying to refer to it by the initials in recognition of the fact that the name itself is problematic. It bends around the object and that bending can magnify the images of objects behind whatever massive thing is doing the lensing. There’s been an effort within the community for a lot of people to refer to only by initials. It’s able to see the gas and dust in things like the cores of interacting galaxies. The thing that jumps out at you is that there are these streaks, these smudges in arcs, circling the central cluster. It’s able to see essentially some of the first galaxies that ever were formed in the cosmos because it can look back more than 13 billion years. This means that it can gather more light and see dimmer objects in the very, very distant universe.

"These stars are responsible for most of the carbon in the universe," Professor De Marco says. "This is not just carbon in the making, but carbon in the ejecting. But with Webb … now you're able to see the small branches and even be able to tell the difference in the shapes of the leaves," Dr Tran says. "You're looking at thousands if not millions of planets in this little patch of the sky." As the two stars dance around each other, they kick up dust and gas, creating ripples of material. Professor De Marco reads the image like a geologist uncovering Earth's history from rock layers. The mid-infrared image below shows a small, dim star nestled next to its brighter, younger companion. Except it's not a jet, it's an edge-on galaxy. This next image captures Stephan's Quintet — a group of five galaxies in the constellation Pegasus — in near-infrared and mid-infrared light. "The outer part is the stuff that came out first, and the inner part is in a sense what came out later," she says. Objects closer to us appear much lighter. The cluster of bright dots in the orange dust is a pod of different-coloured stars forming.

James Webb telescope takes super sharp view of early cosmos (RNZ)

The first full-colour picture from the new James Webb Space Telescope has been released - and it does not disappoint.

It looks like a spaceship from the future." "And by the way, we're going back further, because this is just the first image. But the great mass of this cluster has bent and magnified the light of objects that are much, much further away. Webb identified its super-deep objects after only 12.5 hours of observations. It will make all sorts of observations of the sky, but has two overarching goals. And it is even better than that.

Astronomers and space fans have been waiting years for this moment: The James Webb Space Telescope team has finally made public a handful of stunning images ...

This image of a tight grouping of five galaxies known as Stephan’s Quintet shows in detail the first compact galaxy group ever discovered. JWST is able to infer the presence of clouds and hazes around the planet. Many of Hubble’s now-iconic images were also of nebulae, like the Crab Nebula and Horsehead Nebula. WASP-96 is a gas giant about half the size of Jupiter, and is about 1,150 light-years away. The new images provide a taste of what scientists can achieve with the powerful telescope. This is definitely the hors d'oeuvres, and the main course will be coming out over the months and years ahead,” says Jonathan Lunine, a Cornell University astrobiologist on the JWST team.

Webb is also excellently suited to study the end of a star’s life. The large white galaxies in the middle of the image belong to the cluster and are similar in age to the Sun and Earth. Surrounding and interspersed among the cluster galaxies are more distant galaxies, but stretched into spectacular arcs as if seen through a magnifying glass. During this transit, a portion of the star’s light was filtered through the planet’s atmosphere and left a “chemical fingerprint” in the light’s unique spectrum. It is like the universe in high definition, and I encourage you to look at the full resolution image and zoom in to truly appreciate the details. Webb was designed to collect light across the entire red to mid-infrared spectrum – wavelengths of light that are blocked by Earth’s atmosphere. In them are the oldest galaxies ever seen by human eyes, evidence of water on a planet 1,000 light-years away and incredible details showing the birth and death of stars.
