Glowing streaks of light and warped arcs: Nasa gives glimpse at ‘distant past' through new Webb picture
Galaxy cluster Abell S1063 (Nasa) As part of the 'picture of the month' series, Nasa has revealed a new image taken by the James Webb telescope that gives a look into the distant past. This picture of the galaxy cluster Abell S1063 is a gigantic collection of galaxies lying 4.5 billion light years from Earth as part of the constellation Grus, also known as the Crane. The picture showcases galaxies surrounded by glowing streaks of light and warped arcs, which are of particular interest to scientists, as they represent faint galaxies from the distant past of this universe. Captured after 120 hours of observation, this image represents Webb's deepest look at a single celestial target. This image is a deep field image , capable of capturing pictures of galaxies that have existed as early as 200 million years after the Big Bang. Deep field technology comprises of long exposure photography, focusing on a singular area in the sky, capable of collecting as much light as possible to draw out images of the most distant and faraway galaxies. The Abell cluster was initially observed by the Nasa/ESA Hubble Telescope, a strong gravitational lens, with an aim to use the cluster's image to study the early Universe . by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 5 Books Warren Buffett Wants You to Read In 2025 Blinkist: Warren Buffett's Reading List Undo Upon studying, the image reveals a plethora of lensing arcs around the Abell S1063, providing a peek at previously unseen features and a multitude of faint galaxies. This observation is part of the GLIMPSE programme, which has a mission to study a period called the ' Cosmic Dawn ' when the universe was only a few million years old. Studying images captured through gravitational lensing has the power to enrich our understanding of the universe and the emergence of the very first galaxies.

JWST peers through a cosmic lens in 'deepest gaze' to date

The James Webb Space Telescope captured this stunning image of a galaxy cluster so massive that it serves a gravitational lens, warping the light and revealing more distant galaxies from the early universe. Abell S1063 is a cluster of galaxies that displays a strong gravitational lens effect, in which the light from distant galaxies behind the cluster is bent around it due to Abell S1063's mass, which creates a curvature in spacetime and forms the warped arcs that appear to surround it in the image. JWST's Near-Infrared Camera (NIRCam) was able to use this effect, previously observed by the Hubble Space Telescope, to reveal a multitude of faint galaxies and previously unseen features. Galaxy cluster Abell S1063 lies about 4.5 billion light-years from Earth in the southern constellation Grus, the Crane. The distorted background galaxies are at a range of cosmic distances. JWST is adept at taking these types of images, known as a "deep field." When making these images, the telescope takes a long exposure of a single area of the sky in order to gather as much light as possible. Doing so can help the telescope see distant, faint galaxies that other observatories can't. "With 9 separate snapshots of different near-infrared wavelengths of light, totalling around 120 hours of observing time and aided by the magnifying effect of gravitational lensing, this is Webb's deepest gaze on a single target to date," the European Space Agency wrote in a statement. "Focusing such observing power on a massive gravitational lens, like Abell S1063, therefore has the potential to reveal some of the very first galaxies formed in the early universe." You can learn more about gravitational lensing and how the James Webb Space Telescope was pushed to its limits to see the most distant galaxies.

Ottawa police detective found guilty of discreditable conduct
An Ottawa police detective has been found guilty of discreditable conduct following a lengthy police disciplinary hearing into allegations she invaded the privacy of families by inappropriately accessing files of dead children and asking one parent about a vaccination status. Const. Helen Grus, a detective with the Ottawa Police Service's sexual assault and child abuse unit, was accused of self-initiating "an unauthorized project" by accessing case files to which she wasn't assigned. She also faced accusations that, in late January 2022, she interfered in an investigation by calling and speaking with the father of a deceased infant — inquiring about the COVID-19 vaccination status of the mother. She was suspended with pay a short while later. Grus felt duty-bound to investigate The crux of Grus's argument, as presented to the hearing, was that she took reasonable steps based on a firm belief and that she was unfairly charged for upholding her oath. In his decision, Supt. (retired) Chris Renwick details that the detective noticed a "doubling or tripling of infant deaths" and saw it as "her duty to investigative criminal negligence on the part of the government." Grus' defence lawyer, Bath-Shéba van den Berg, submitted that there is no such thing as an unauthorized investigation and no such thing as unlawful interference by making a phone call for policing purposes, according to Renwick's summary. She told the tribunal that Grus had intended to inform her chain of command of her actions, but her suspension prevented it — as did former police Chief Peter Sloly's departure soon after. The decision also notes that, according to Grus' lawyers, she was shut down by a lie concocted by her unit that led to the "never seen before" charge, influenced by "political control of the police." Renwick's decision also details that, in her affidavit, Grus determined that she "at most" stepped on her colleague's toes. But in the end, the hearing officer wasn't buying it Renwick said Grus' description of events demonstrated, at best, a poorly thought-out criminal negligence investigation, kept from her higher ups and "with national implications far beyond her individual capabilities and resources." "It can certainly be viewed as an attempted weaponization/politicalization of police powers to exert pressure on municipal, provincial, and federal health officials," Renwick wrote. He wrote that Grus' failure to document her call with the father only compounded the potential damage to the lead investigator's relationship and trust with the family. Renwick said, while he accepted the underlying motivation was one of concern, he found Grus had applied her own personal views, formed by her self-initiated research and her strong opposition to her employer's decision to implement a mandatory vaccination policy. Issues with decorum He found her guilty under the Police Services Act. "Grus allowed her personal beliefs and opinions to seep into her professional responsibilities and cloud her judgment and, ultimately, her professional conduct," he wrote. In his decision, Renwick also took aim at some of the behaviour he saw throughout the hearing, which kicked off in August of 2023. He said poor decorum by counsel led to "name calling and accusations," with constant objections adding several days to the hearings. He said disruptions by members of the public were another issue, with the hearing having to be stopped on two occasions to remove disruptive persons. He said police eventually had to initiate a security protocol, significantly adding to the tension within the room. According to the police service on Tuesday, no dates have been set for submissions on penalty as of yet. The Ottawa Police Association said Tuesday Grus is still employed by the Ottawa police. The police service settled a civil claim related to Grus' actions in December 2023. In April 2024 Grus launched a lawsuit against the CBC over articles concerning the accusations. That legal proceeding has not been resolved.
