James Webb telescope captures one of the deepest-ever views of the universe — Space photo of the week

Quick facts What it is: The Hubble Ultra Deep Field, revisited by the James Webb Space Telescope Where it is: Close to the Big Dipper in the night sky When it was shared: Aug. 1, 2025 The James Webb Space Telescope's (JWST) latest extragalactic survey has revealed fainter and more distant objects than ever before, some dating back to the earliest periods of the universe. But it stands on the shoulders of a giant: When NASA published the Hubble Ultra Deep Field image in 2004, it stunned the world of astronomy. A composite of 800 images from exposures totaling 11 days, the deep image of an otherwise unremarkable part of the night sky revealed nearly 10,000 galaxies, many among the most distant known. Now, JWST has observed that same patch of sky with different eyes — and found 2,500 more objects. Crucially, they're even more distant. JWST's new take on the Hubble Ultra Deep Field, named the MIRI Deep Imaging Survey (MIDIS), is the deepest-ever mid-infrared image of that part of the night sky. The extraordinary new image is the result of nearly 100 hours of observing time using the space observatory's Mid-Infrared Instrument (MIRI) and Near-Infrared Camera (NIRCam). It includes hundreds of extremely red galaxies, some of which may date back to less than a billion years after the Big Bang. Related: 42 jaw-dropping James Webb Space Telescope images At the core of the composite image is one ultralong exposure. Using just one of MIRI's filters, JWST took an exposure of the night sky for 41 hours — the longest single-filter observation it has performed of an extragalactic field to date. The plan was to capture galaxies in mid-infrared light — something neither Hubble nor human eyes can detect — which also revealed previously unseen regions of dust and old, red stars.

Processing such images requires filters that assign a different color to each different wavelength of light. In this image, galaxies rich in dust and star-forming activity are orange and red, extremely distant compact galaxies are greenish, and galaxies bright in the near-infrared are blue and cyan. Researchers described the image in a paper in the journal Astronomy & Astrophysics, along with a slider tool, a pan video and a transition video with the Hubble Ultra Deep Field for comparison.

60-Year-Old Gave Himself Early 20th Century Psychosis After He Went To ChatGPT For Diet Advice
A 60-year-old man gave himself an uncommon psychiatric disorder after asking ChatGPT for diet advice in a case published Tuesday by the American College of Physicians Journals. The man, who remained anonymous in the case study, told doctors he had eliminated sodium chloride, commonly known as table salt, from his diet after reading about its negative health effects. He said he could only find sources telling him how to reduce salt, but not eliminate it completely. Inspired by his nutrition studies in college, the man decided to completely eliminate sodium chloride from his diet as a personal experiment, with consultation from Chat GPT, researchers wrote. He maintained multiple dietary restrictions and even distilled his own water at home. 'For 3 months, he had replaced sodium chloride with sodium bromide obtained from the internet after consultation with ChatGPT, in which he had read that chloride can be swapped with bromide, though likely for other purposes, such as cleaning,' the case study read. While excess sodium can raise blood pressure and increase the risk of health issues, it is still necessary to consume a healthy amount of it. The man, who had no psychiatric history, eventually ended up at the hospital, worried that his neighbor was poisoning him. He told doctors he was very thirsty, but paranoid about the water he was offered. 'In the first 24 hours of admission, he expressed increasing paranoia and auditory and visual hallucinations, which, after attempting to escape, resulted in an involuntary psychiatric hold for grave disability,' the study read. Doctors concluded that the man was suffering from bromism, or bromide toxicity, a condition that is rare today but was more common in the early 20th century. The research noted that bromide was found in several over-the-counter medicines back then and contributed to up to 8% of bromism-related psychiatric admissions at that time. The hospital treated the man for psychosis and discharged him weeks later. His case highlights the potential pitfalls of using AI to seek medical tips. Dr. Margaret Lozovatsky, a pediatrician, warned last year that AI often misses crucial context. 'Even if the source is appropriate, when some of these tools are trying to combine everything into a summary, it's often missing context clues, meaning it might forget a negative,' she told the American Medical Association. 'So, it might forget the word 'not' and give you the opposite advice.' Related...

One of the Most Celebrated Astronomical Events of 2025 Is Peaking This Week With Fiery Streaks and Bright Fireballs—What to Know
Make sure to look up at the night sky this week because Mother Nature is going to be putting on a show. The annual Perseid Meteor Shower is set to peak around Aug. 12 and 13, according to the American Meteor Society, and it's likely to be spectacular. During the event, which usually happens around July and August, it is typically possible to see dozens of meteors every hour. The meteor shower is the result of the Earth crossing paths with the dust cloud from the comet Swift-Tuttle, which gives us the annual Perseids. The comet, whose name comes from the fact that the most radiant part of the sky during the meteor shower is near the Perseus constellation, orbits the sun every 133 years. Perseids are also known for their fireballs, according to NASA, which are "larger explosions of light and color that can persist longer than an average meteor streak," which emerge from "larger particles of cometary material." However, visibility this year may be impacted by another wonder of the night sky: the moon. That's because the moon is expected to be 84% full and "will severely compromise this shower at the time of maximum activity. Such conditions will reduce activity by at least 75 percent as only the brighter meteors will be visible,' the American Meteor Society said. Perseids are best viewed in the Northern Hemisphere before dawn, NASA noted, though it is possible to spot the meteor showers as early as 10 p.m. No binoculars or telescopes are necessary to see the Perseids, according to but the meteor shower is best viewed from dark sky destinations with minimal light pollution and wide open skies. Viewers in the Southern Hemisphere may also have the opportunity to spot meteor showers this month. The alpha Capricornids and the Southern delta Aquariids will both be active through August 12, but their peak has unfortunately passed. The alpha Capricornids are known for their bright fireballs and can be seen on both sides of the equator, while the Southern delta Aquariids are best viewed from the southern tropics. It has been a good year for space enthusiasts with the northern lights putting on an amazing show thanks to the period known as solar maximum. And in addition to the meteor showers, there are several breathtaking astronomical events happening in August from a full sturgeon moon to the chance to spot Mercury, and more.
