The AGO didn’t just embroil itself in controversy over Nan Goldin’s work – it missed out on a magnificent piece of art The gallery’s decision not to acquire ‘Stendhal Syndrome’ was based less on artistic merit than the politics of the artist

Thanks @marshalederman.bsky.social for this article. Artist Nan Goldin's "Stendhal Syndrome" artwork sounds formidable - Hey, National Gallery of Canada #NGC www.theglobeandmail.com/gift/92f31b0...

**Astronomers using theNASA/ESA/CSA James Webb Space Telescope have produced a spectacular infrared image of the spiral galaxy NGC 5134.** This Webb image shows NGC 5134, a spiral galaxy some 65 million light-years away in the constellation of Virgo. Image credit: NASA / ESA / CSA / Webb / A. Leroy. NGC 5134 is located approximately 65 million light-years away in the constellation of Virgo. Otherwise known as ESO 576-52, LEDA 46938 or IRAS 13225-2052, this galaxy was discovered by the German-British astronomer William Herschel on March 10, 1785. NGC 5134 is a member of the NGC 5084 group, a group of five galaxies that also includes NGC 5084, NGC 5087, ESO 576-50 and ESO 576-40. “Because of the galaxy’s relative proximity, Webb can spot incredible details in its tightly wound spiral arms,” the Webb astronomers said in a statement. The new image of NGC 5134 includes both infrared observations from both Webb’s Mid-InfraRed Instrument (MIRI) and the telescope’s Near-InfraRed Camera (NIRCam). “MIRI collects the mid-infrared light emitted by the warm dust that speckles NGC 5134’s interstellar clouds, tracing clumps and strands of dusty gas,” the astronomers said. “Some of the dust is composed of complex organic molecules called polycyclic aromatic hydrocarbons, which feature interconnected rings of carbon atoms and provide a way for astronomers to study the chemistry happening in interstellar clouds.” “NIRCam records shorter-wavelength near-infrared light, mostly from the stars and star clusters that dot the galaxy’s spiral arms.” “Together, the MIRI and NIRCam data paint a portrait of a galaxy in constant ebb and flow.” “The gas clouds that billow along NGC 5134’s spiral arms are the sites of star formation, and each star that forms chips away at the galaxy’s supply of star-forming gas,” the researchers said. “When stars die, they recycle some of that gas back into the galaxy.” “Massive stars more than about eight times the mass of the Sun do so spectacularly, in cataclysmic supernova explosions that spread stellar material across hundreds of light-years.” “Stars like the Sun give back some of their material as well, though more gently.” “These stars will balloon into bubbling red giants before shrugging off their atmospheres and sending them into space.” “Whether expelled by explosive supernovae or gentle red giants, this gas can then be incorporated into new stars.”

**Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have for the first time identified the progenitor of a nearby supernova — a red supergiant star cloaked in thick, dust-rich shrouds that made it invisible to previous observatories.** The main image at left shows a combined Webb and Hubble view of the spiral galaxy NGC 1637, with the region of interest in the top right; the remaining three panels show a detailed view of a red supergiant star before and after it exploded; the star is not visible in the Hubble image before the SN 2025pht explosion, but appears in the Webb image; the July 2025 view from Hubble shows the glowing aftermath of the explosion. Image credit: NASA / ESA / CSA / STScI / C. Kilpatrick, Northwestern / A. Suresh, Northwestern / J. DePasquale, STScI. The supernova event in question, designated SN 2025pht, was discovered in NGC 1637 on June 29, 2025. Astronomers immediately turned their resources to this supernova to learn more about it. But Northwestern University astronomer Charlie Kilpatrick and his colleagues instead turned to archives, seeking to use pre-supernova images to identify exactly which star among many had exploded. The images of NGC 1637 taken by Webb’s MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera) in 2024 showed a single red supergiant star located exactly where the supernova now shines. “We’ve been waiting for this to happen — for a supernova to explode in a galaxy that Webb had already observed,” Dr. Kilpatrick said. “We combined Hubble and Webb data sets to completely characterize this star for the first time.” “It’s the reddest, most dusty red supergiant that we’ve seen explode as a supernova,” said Aswin Suresh, a graduate student at Northwestern University. This excess of dust could help explain a long-standing problem in astronomy that could be described as the case of the missing red supergiants. Astronomers expect the most massive stars that explode as supernovae to also be the brightest and most luminous. So, they should be easy to identify in pre-supernova images. However, that hasn’t been the case. One potential explanation is that the most massive aging stars are also the dustiest. If they’re surrounded by large quantities of dust, their light could be dimmed to the point of undetectability. The Webb observations of SN 2025pht support that hypothesis. “I’ve been arguing in favor of that interpretation, but even I didn’t expect to see it as extreme as it was for SN 2025pht,” Dr. Kilpatrick said. “It would explain why these more massive supergiants are missing because they tend to be more dusty.” The authors also found that the dust surrounding the star is likely rich in carbon — an unexpected result, since scientists would normally anticipate silicate-dominated dust in such an environment. They speculate that this carbon might have been dredged up from the star’s interior shortly before it exploded. “Having observations in the mid-infrared was key to constraining what kind of dust we were seeing,” Suresh said. The team’s paper was published In October 2025 in the _Astrophysical Journal Letters_. _____ Charles D. Kilpatrick _et al_. 2025.
