The James Webb is one of the greatest advances in astronomical science in years, and to reiterate that title, the telescope captures multiple images of distant bodies in stunning levels of detail. On Thursday (05), the University of Texas released a new photograph recorded by the infrared sensors of the NASA observatory.
The image below shows a primitive galaxy — cataloged as “EGS 23205” — captured by the Hubble Telescope (left) and James Webb (right). The evolution in image quality is significant, as astronomers were able for the first time to observe more details of their star cluster. Check out:
The photograph produced with infrared technology shows what the galaxy was like 11 billion years ago. For a chronological notion, remember that scientists estimate that the Universe is about 13.7 billion years old. Despite this advanced age, the oldest galaxy is theorized to be GLASS-z12, which would have existed about 350 million years after the Big Bang.
According to experts, the sharpest image captured by the James Webb telescope allows extracting more information about the EGS 23205, which seemed to have a Formation similar to the Milky Way due to its large stellar barriers that draw gas towards the core, spurring star formation and feeding its central black hole.

“The barely visible barriers in the Hubble data have just appeared in the James Webb image, showing the telescope’s tremendous power to see the underlying structure in galaxies,” said Shardha Jogee, an astronomer at the university and co-author of the research that analyzed galaxy formation. primitive.
James Webb should continue its incredible journey of discoveries in 2023. The telescope is considered a “new era of astronomy” for revealing data that Hubble, launched more than three decades ago and still in activity, could not provide.
