Webb telescope captures deep view of ancient galaxies
The James Webb space telescope is offering scientists a glimpse into the distant past. (ESA/Webb pic) PARIS : The James Webb space telescope's deepest view of a single target depicts spinning arcs of light that are galaxies from the universe's distant past, the European Space Agency said Tuesday. The new image took the world's most powerful telescope more than 120 hours to capture, making it the longest Webb has ever focused on a single target. It is also 'Webb's deepest gaze on a single target to date', the European Space Agency (ESA) said in a statement, making the image one of the deepest ever captured of the cosmos. At the bright centre of the image is a massive cluster of galaxies called Abell S1063, which is 4.5 billion light years from Earth. But it is not the true target. Such huge celestial objects can bend the light of things behind them, creating a kind of magnifying glass called a gravitational lens. Therefore the 'warped arcs' spinning around the Abell S1063 are what really interest scientists, the ESA said in a statement. Because looking into distant space also means looking back in time, scientists hope to learn how the first galaxies formed during a period known as the Cosmic Dawn, when the universe was only a few million years old. The image includes nine separate shots of different near-infrared wavelengths of light, the ESA said. Since coming online in 2022, the Webb telescope has ushered in a new era of scientific breakthroughs. It has also revealed that galaxies in the early universe are far bigger than scientists expected, leading some to suspect there might be something wrong with our understanding of the cosmos.

Webb Telescope Peers Back in Time Via New 'Deep Field' Image
The James Webb Space Telescope has recently captured some breathtaking shots of individual space bodies, from Neptune and its dreamy auroras to Jupiter's own massive light shows. But the telescope's latest image is going for depth, not focus. In a multi-layered snapshot shared by the European Space Agency (ESA) Tuesday, Webb peers back in time, bringing astronomers one step closer to examining so-called "Cosmic Dawn." This period began when the universe was just a few million years old, and based on what astronomers currently know, that's when the version of the universe we observe today began to take shape. Cosmic Dawn should have quite a bit to say about why our stellar setting is the way it is, making it a vital area of study for space scientists. But imaging Cosmic Dawn is easier said than done, and theory can only go so far. Tuesday's Webb image is as good a starting point as any. The image depicts Abell S1063, a behemoth galaxy cluster 4.5 billion light-years from Earth. While the Hubble Space Telescope captured Abell S1063 nine years ago, the galaxy cluster holds too much potential to be used just once: Its size bends the light of distant galaxies positioned "behind" it, allowing it to serve as a strong gravitational lens. Credit: ESA/Webb, NASA & CSA, H. Atek, M. Zamani In an effort to pick up where Hubble left off, Webb's NIRCam (Near-Infrared Camera) gazed at Abell S1063 and its surroundings. A total of 120 observation hours allowed Webb to take nine snapshots at various near-infrared wavelengths. Stacked together, these snapshots offer what the ESA calls "Webb's deepest gaze on a single target to date." While Abell S1063 dominates the image, the warped streaks of light are gravitational lensing in action. The streaks originate from "faint galaxies from the universe's distant pass," as the ESA puts it, lending scientists the potential to develop our understanding of the emergence of the first galaxies." And on that front, research has already begun. According to two preprint papers published on the arXiv, an international team of astrophysicists has used Webb's data to identify a host of candidate galaxies that could have formed as early as 200 million years after the Big Bang. They've even spotted signs of the first stars in the universe.

Webb telescope stares deeper into space than ever, revealing warped light from galaxies born near the dawn of time
PARIS, May 28 — The James Webb space telescope's deepest view of a single target yet depicts spinning arcs of light that are galaxies from the universe's distant past, the European Space Agency said Tuesday.

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.
