Illustration of how a failed supernova can become a black hole. (P. Jeffries/STScI/NASA/ESA) In 2009 a giant star 25 times more massive than the Sun simply…vanished. Okay, it wasn't quite that simple. It underwent a period of brightening, increasing in luminosity to a million Suns, just as if it was ready to explode into a supernova. But then it faded rather than exploding. And when astronomers tried to see the star, using the Large Binocular Telescope (LBT), Hubble, and the Spitzer space telescope, they couldn't see anything. The star, known as N6946-BH1, is now considered a failed supernova. The BH1...

Explanation: Ringed ice giant Neptune lies near the center of this sharp near-infrared image from the James Webb Space Telescope. The dim and distant world is the farthest planet from the Sun, about 30 times farther away than planet Earth. But in the stunning Webb view, the planet's dark and ghostly appearance is due to atmospheric methane that absorbs infrared light. High altitude clouds that reach above most of Neptune's absorbing methane easily stand out in the image though. Coated with frozen nitrogen, Neptune's largest moon Triton is brighter than Neptune in reflected sunlight, seen at the upper left sporting...

For the second time, the James Webb Space Telescope (JWST) has looked for and failed to find a thick atmosphere on an exoplanet in on one of the most exciting planetary systems known. Astronomers report today that there is probably no tantalizing atmosphere on the planet TRAPPIST-1 c, just as they reported months ago for its neighbour TRAPPIST-1 b.There is still a chance that some of the five other planets in the TRAPPIST-1 system might have thick atmospheres containing geologically and biologically interesting compounds such as carbon dioxide, methane or oxygen. But the two planets studied so far seem to...

Researchers using NASA's James Webb Space Telescope have discovered multiple debris rings within a previously discovered ring around the young star Fomalhaut. Photo Courtesy of NASA May 9 (UPI) -- Researchers using NASA's James Webb Space Telescope observed multiple debris rings surrounding a young star. The James Webb Telescope's Mid-Infrared Instrument, which is designed to capture very long wavelengths of light, found three nested belts surrounding the Fomalhaut star, out to a distance of up to 14 billion miles, NASA said Monday. Observations by NASA's Infrared Astronomical Satellite first discovered Fomalhuat's dust ring, the first asteroid belt seen outside of...

Webb’s infrared image highlights the planet’s dramatic rings and dynamic atmosphere. This zoomed-in image of Uranus, captured by Webb’s Near-Infrared Camera (NIRCam) on 6 February 2023, reveals stunning views of the planet’s rings. The planet displays a blue hue in this representative-colour image, made by combining data from two filters (F140M, F300M) at 1.4 and 3.0 microns, shown here as blue and orange, respectively. On the right side of the planet is an area of brightening at the pole facing the Sun, known as a polar cap. This polar cap is unique to Uranus because it is the only planet...

The James Webb Space Telescope (JWST) has captured an amazing image of Uranus, showing in great detail the ice giant's ring system, its brightest moons and its dynamic atmosphere. The new observation, made on Feb. 6, follows a similarly stunning photo JWST captured recently of the solar system's other ice giant, Neptune. The new Uranus image shows 11 of the planet's 13 known rings, some of which are so bright that they blend together somewhat. What will really astound astronomers, however, is the fact that JWST's Near Infrared Camera (NIRCam) instrument is sensitive enough to have captured the innermost two...

JWST's new image of WR 124 and its nebula. (NASA, ESA, CSA, STScI, Webb ERO Production Team) There's scintillating beauty to be found in cosmic death. In a new image from the JWST, the spectacular final throes of a star nearing the end of its life are revealed in all their intricate detail. Located in the constellation Sagittarius, the star WR 124 is what's known as a Wolf-Rayet, which are rarely seen in the Milky Way. That's because only certain stars turn into Wolf-Rayets, and even then their time in that phase is so short; in just a few hundred...

Scientists say that images from the James Webb Space Telescope may change how they understand the origins of the universe after they discovered "the impossible." The findings were published in the journal "Nature" on Wednesday. Astronomers expected to find "tiny, young, baby galaxies" from the cosmic history documented in the images, but they found something else entirely. The study's lead author, Ivo Labbé, explained how shocked he was when he realized what the images meant. "Little did I know that among the pictures is a small red dot that will shake up our understanding of how the first galaxies formed...

[Image description: Many stars and galaxies lie on a dark background, in a variety of colours but mostly shades of orange. Some galaxies are large enough to make out spiral arms. Along the bottom of the frame is a large, detailed spiral galaxy seen at an oblique angle, with another galaxy about one-quarter the size just beneath it. Both have a brightly glowing core, and areas of star formation which light up their spiral arms.] A crowded field of galaxies throngs this Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope, along with bright stars crowned with Webb’s...

Distant Galaxy The image of the most distant galaxy, GHZ2/GLASS-z12. (NASA/ESA/CSA/T. Treu, UCLA/NAOJ/T. Bakx, Nagoya U) A galaxy whose light has traveled nearly 13.5 billion years to reach us has just been confirmed as the earliest galaxy found to date. By studying the oxygen content of the galaxy with the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have precisely dated it to just 367 million years after the Big Bang, a time when the first lights in the Universe were still switching on and starting to propagate freely through space. The result confirms observations made by JWST, and offers new information...

The most comprehensive plans need a sprinkle of luck, even in space. VIDEO AT LINK In October 2022, the James Webb Space Telescope (JWST or Webb) watched as Chariklo, a tiny ringed asteroid, eclipsed a star. This event, called an occultation, marked a first for Webb. At the month's end, Webb turned toward Chariklo again and notched another victory: For the first time, astronomers analyzing the telescope's data spotted clear signs of water ice, the presence of which was only hinted at until now. These observations will guide astronomers to better understand the nature and behavior of tiny bodies in...

Artist conception of the James Webb Space Telescope. Credit: NASA GSFC/CIL/Adriana Manrique Gutierrez On Sunday, January 15, 2023, the James Webb Space Telescope’s Near Infrared Imager and Slitless Spectrograph (NIRISS) experienced a communications delay within the instrument, causing its flight software to time out. The instrument is currently unavailable for science observations while NASA and the Canadian Space Agency (CSA) work together to determine and correct the root cause of the delay. There is no indication of any danger to the hardware, and the observatory and other instruments are all in good health. The affected science observations will be...

An interstellar row has broken out between the Royal Astronomical Society and Nasa over claims a former boss purged gay staff. The James Webb space telescope – the most powerful observatory ever built – was named in honour of the man who ran the space agency in the 1960s. But the 202-year-old society has ordered its 4,000 members to refrain from using the telescope's full title following claims that Mr Webb was a homophobe who oversaw a purge of gay employees.

Carina Nebula (NGC 3324) captured by Webb’s Near-Infrared Camera (NIRCam) (NASA/ESA/CSA/STScI) The powerful James Webb Space Telescope is a mighty technological tool. Astrophysicists first conceived it over 20 years ago, and after many twists and turns, it was launched on December 25, 2021. Now it's in a halo orbit at the Sun-Earth L2 point, where it will hopefully continue operating for 20 years. It's only been a few months since its first images were released, and it's already making progress in answering some of the Universe's most compelling questions. In a newly-released image, the JWST peered deep inside massive clouds...

The location of the most distant galaxy ever detected. (NASA, ESA, CSA, M. Zamani/ESA/Webb) Light that has traveled for over 13.4 billion years to reach our neighborhood of space has been confirmed as originating from the earliest, most distant galaxy detected yet. That places the most distant of these four very young objects at the very dawn of the Universe, just a short time after the Big Bang – a time period when the Universe was still foggy and bleary and the first rays of light were penetrating the darkness. So detailed are the JWST's long spectroscopic observations that researchers...

Editor’s Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. We spoke with Kristen McQuinn of Rutgers University, one of the lead scientists on Webb Early Release Science (ERS) program 1334, focused on resolved stellar populations. These are large groups of stars – including stars within the dwarf galaxy Wolf–Lundmark–Melotte (WLM) – that are close enough for Webb to differentiate between individual stars, but far enough for Webb to capture a large number of stars at once. Labeled, side-by-side comparison of dwarf galaxy Wolf-Lundmark-Melotte (WLM) images, as seen by Spitzer’s...
