Eagle eye of James Webb Space Telescope spots two of most distant galaxies ever seen

NEW DELHI: The James Webb Space Telescopehas successfully spotted two of the most distant galaxies ever seen. The second and the fourth most distant galaxies ever seen were found by the eagle eye of the Telescope. Bingjie Wang of the Penn State Eberly College of Science and a member of the JWST UNCOVER team successfully discovered the two redshift galaxies at a distance.
A massive gravitational lens which is located about 3.5 billion light years from us and present in the form of the galaxy cluster known as Abell 2744 proved to be a great help for the discovery. The immense gravity of the cluster sufficiently warps the fabric of space-time to magnify the light of galaxies at a great distance. Bingjie and the member of the JWST UNCOVER used the James Webb Space Telescope to spot the galaxies magnified by the cosmic lens.
The team then identified the two high-redshift galaxies. One, which has been designated UNCOVER-z13 has a redshift of 13.079. It is the second most distant galaxy known. The other galaxy, UNCOVER-z12, has a redshift of 12.393. It is the fourth most distant galaxy.
Wang described the difference between previously and currently discovered galaxies. “Previously discovered galaxies at these distances appear as a dot in our images,” Wang said. “But one of ours appears elongated, almost like a peanut, and the other looks like a fluffy ball.”
“It is unclear if the difference in size is due to how the stars formed or what happened to them after they formed, but the diversity in the galaxy properties is really interesting,” said Wang. “These early galaxies are expected to have formed out of similar materials, but already they are showing signs of being very different than one another.”
