NASA’s James Webb Space Telescope (JWST) has detected galaxies similar to the Milky Way, which formed when the universe was only 25% of its current age, with one of the detected galaxies dating back 11 billion years. according to the Daily Mail.
The team identified 6 prominent galaxies between 8 and 11 billion years old, similar to the Milky Way, which formed when the universe was 25% of its current age.

These galaxies contain enormous amounts of gas, dust and stars, and are also the first to be distinguished by starbars, which are clusters of stars that extend from the galactic center to its outer disk, and are characteristic of spiral galaxies.
Starbars exist in our own galaxy, but this is the first time scientists have seen them in the early universe in another galaxy, a discovery that will prompt astrophysicists to improve their theories of galaxy evolution.
Sharda Joji, professor of astronomy at the University of Texas at Austin, said in a statement: “This discovery means that models of galaxy evolution now have a new path. The James Webb Telescope has seen it as a galaxy at spiral, showing the great power of the James Webb telescope.
The bars are found in up to 65% of spiral galaxies and affect the motion of stars, dust and gas. Scientists also believe that the rods act like a funnel, promoting star formation. The bars also help the formation of supermassive black holes in the center of galaxies.
