First images captured by JWS telescope released by NASA Window to the dawn of the new universe. The pictures show elements of the universe as they were 13bn years ago, reshaping our understanding of the cosmos. Mon 11 Jul 2022 19.24 EDT Nasa has released an image of far-flung galaxies as they were 13bn years ago, the first glimpse from the most powerful telescope ever launched into space, which promises to reshape our understanding of the dawn of the universe. This particular cluster as it was 4.6bn years ago, as well as the light from many different twinkling galaxies which are among the oldest in the universe. It is “historic” and provided “a new window into the history of our universe”. It’s an historic moment for science and technology, for USA and all of humanity.” Bill Nelson, administrator of Nasa, said the image showed the light of galaxies bending around other galaxies, traveling for billions of years before reaching the telescope. “We are looking back more than 13 billion years,” he said, adding that more images to be released by the space agency would reach back further, to about 13.5 billion years, close to the estimated start point of the universe itself. “We are going back almost to the beginning,” he said. Experts have said the telescope, three decades in the making and launched last year, could revolutionize our understanding of the cosmos by providing detailed infrared images of the universe. The initial goal of the project was to see the first stars and galaxies formed following the big bang, watching “the universe turn the lights on for the first time”, as Eric Smith, Webb program scientist, put it. The telescope should be considered “one of humanity’s great engineering achievements”, “It’s hard to take in how fantastic JWST has turned out to be. It is utterly amazing.” Nasa said JWST has five initial cosmic targets for observation, including the Carina nebula, a sort of celestial nursery where stars form. The nebula is about 7,600 light years away and is home to many enormous stars, several times larger than the sun. Other areas of focus include WASP-96 b, a giant planet outside our solar system that is made mainly of gas; the southern ring nebula, an expanding cloud of gas surrounding a dying star that’s 2,000 light years from Earth; and Stephan’s quintet, notable for being the first compact galaxy group discovered in 1877.
