telescope monitor The alien James Webb (JWST) Galaxies-Like from NASA Our galaxy is the Milky Waywhich formed when the universe was only 25% of its present age, and a single galaxy was 11 billion years old, and these huge clusters of gas, dust and stars are also the first to feature star bars, which they are elongated features of stars extending from the centers of galaxies to their outer disks shortly after the Big Bang which occurred 13.7 billion years ago.
According to the British newspaper ‘Daily Mail’, there are starbars in our galaxy, but this is the first time scientists have seen them in a galaxy that signals the beginning of the universe, a discovery that will require astrophysicists to improve their theories on the evolution of galaxies.
“This discovery of the first bars means that models of galaxy evolution now have a new path through the bars to accelerate the production of new stars in the early epochs,” Sharda Joji, a professor of astronomy at the University of Texas, said in a statement. in Austin. .
NASA’s Hubble Space Telescope has detected rods before, but never at such a young age.
The team identified six major galaxies between eight billion and 11 billion years old, and Yuchen ‘Kay’ Guo, the graduate student who led the analysis, said: ‘For this study, we are examining a new system in which no one has used this kind of data or conducted this kind of quantitative analysis before, so everything is new… it’s like entering a forest that no one has ever been in before.”
It is worth noting that stellar rods are found in up to 65% of spiral galaxies and affect the motion of stars, dust and gas. Scientists believe that the rods act like a funnel, drawing material into the bulge from the disk and promoting the formation Stellar Bars also help the formation of supermassive black holes in the center of galaxies by directing the gas in part.
