Universe's Earliest Light Revealed: James Webb Telescope Captures Stunning Image Of Cosmic Dawn
Last Updated: James Webb Space Telescope has captured the deepest and clearest image to date, offering us a glimpse of the universe's beginning, known as the 'Cosmic Dawn' The James Webb Space Telescope (JWST), the most powerful space observatory ever built, has achieved a remarkable feat that will excite everyone interested in space science. This telescope has captured the deepest and clearest image to date, offering us a glimpse of the universe's beginning, known as the 'Cosmic Dawn.' 'Cosmic Dawn' refers to the period when the universe was very young, just a few hundred million years old. Scientists believe that during this time, stars and galaxies began forming for the first time, roughly 13 billion years ago. Until now, it has been very difficult to observe such ancient objects directly. advetisement How Was This Picture Taken? In this historic image, the James Webb Telescope focused on a massive galaxy cluster called 'Abell S1063,' located about 4.5 billion light years away from Earth. This cluster was previously observed by the Hubble Telescope, but James Webb's more powerful infrared camera, NIRCam, allowed it to see deeper into space. The telescope observed this region continuously for 120 hours, capturing nine different images that were combined into a single, stunning picture. This is being called James Webb's deepest view yet. What Was Seen In The Picture? Behind the large galaxies in the image, faint, curved lines of light are visible. These lines are actually light from extremely distant galaxies that cannot be seen directly. The gravitational lensing effect caused by the massive galaxy cluster bends their light towards us, making them visible. Why Is This Discovery Special? Scientists say this image provides evidence that some galaxies formed just 200 million years after the universe came into existence. In other words, we can now witness the moments when the universe first began to 'shine.' The data also hints at glimpses of the very first stars, which is a major breakthrough. How close are we to understanding the universe's mysteries? This image is not just a scientific achievement; it is like a window into time. It proves that we have taken the first step towards uncovering the true story of the universe's birth. The success of the James Webb Telescope shows that humanity is now closer than ever to solving some of the oldest mysteries of time and space. Watch India Pakistan Breaking News on CNN-News18.

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.
