Scientists have made a new discovery, thanks to the “James Webb” telescope of the American agency “NASA”, which represents a new scenario for how young galaxies similar to the “Milky Way” galaxy to which the solar system belongs are formed.
The British newspaper “The Independent” said that the “James Webb” telescope took new images of young galaxies billions of years old, similar to the “Milky Way”, which goes by another name, the “Milky Way”.
The discovery of these barred galaxies will help refine theories about the evolution of the universe, say the researchers, some of whom work at the University of Austin in Texas.
Starbars play a critical role in the evolution of galaxies by pumping gas into their central regions and contributing to star formation, according to a study published in The Astrophysical Journal Letters.
The most important points of the study
- The study highlights several barred spiral galaxies that are 8 billion years old.
- Previous studies pointed to the existence of this type of galaxy.
- In the new study, the researchers say that images collected by the previous Hubble Telescope have not previously revealed the stellar features of these galaxies. For example, there is a rib galaxy called “EGS-23205”, the images taken by “Hubble” appear to be slightly larger than a “mark on a hard drive”, but the images collected by the new “James Webb” telescope, show that it’s a beautiful spiral galaxy with clear star bars.”
The skills of James Webb
Scientists have attributed the new discovery to James Webb’s use of larger mirrors, which give him the ability to gather light, allowing him to see more with greater precision.
Scientists have worked to visually examine hundreds of galaxies, looking for those that contain star bars, which has helped narrow the list down to a few dozen for analysis with more intensive approaches.
University of Austin astronomer and co-author of the study, Sharda Jogi, said: ‘The bars were barely seen in the Hubble data, they only appeared in James Webb’s images, showing the telescope’s enormous capabilities in showing the basic structure of galaxies,” according to Sky News Arabia.
And he continued: “The rods help solve the problem of supply chains in the galaxies, and just as we have to get the raw materials from the port to the factories to make new products, the stellar rods serve to transport the gas to the central region when the il gas turns into new stars 10 to 10 100 times faster than the rest of the galaxy.”
Scientists say the new discovery about starbars during the early universe will ‘shake up’ scenarios for the evolution of galaxies.
Jogi said there is a new scenario for the evolution of galaxies, which is that rod cells accelerated star production in the early eras.
