And helps discover these galaxies, which contain star bars, in revise Theories regarding the evolution of the universesay the researchers, some of whom work at the University of Austin in Texas State American.
The stellate rods play a pivotal role in evolution galaxies By pumping gas into its central regions and contributing to the formation starsAccording to a study published in the journal "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 indicated the existence of this type of galaxies.
- In the new study, the researchers say, the images collected by the previous telescope "Hubble"The stellar features of these galaxies have not been previously revealed. For example, there is a bar galaxy called "EGS-23205" Pictures were taken of her via "Hubble" It appears to be slightly larger than "mark on a hard disk"but the images collected by the new telescope "James Webb"it appears to be a beautiful spiral galaxy with pronounced star bars".
Capabilities "James Webb"
Scientists attributed the new discovery to the use of "James Webb" Larger mirrors, giving it the ability to gather light, allowing it to see more with greater resolution.
The scientists worked to visually review hundreds of galaxies, looking for those that contain star bars, which helped narrow the list down to a few dozen for analysis with more intensive approaches.
University of Austin astronomer and study co-author Sharda Jogi said: "Barely visible in the Hubble data, the bars have just appeared in the James Webb images, showing the telescope’s incredible capabilities in revealing the basic structure of galaxies.".
Follow up: "Rods help solve the problem of galactic supply chains, and just as we need to bring raw materials from port to factories to make new products, stellar rods transport gas in the central region when the gas turns into new stars at a rate of 10-100 times more. from the rest of the galaxy".
Scientists say the new discovery regarding stellar bars during the early universe "will shake" Galaxy evolution scenarios.
Jogi stated that there is a new scenario for the evolution of galaxies, which is that the rods accelerated the production of stars in the early ages.

James Webb’s abilities
Scientists attributed the new discovery to James Webb’s use of larger mirrors, which give him the ability to collect light, allowing him to see more with more precision.
The scientists worked to visually review hundreds of galaxies, looking for those that contain star bars, which helped narrow the list down to a few dozen for analysis with more intensive approaches.
University of Austin astronomer and study co-author Sharda Jogi said: “The bars that were barely visible in the Hubble data have just appeared in the James Webb images, demonstrating the telescope’s tremendous capabilities in showing the underlying structure of galaxies.”
And she continued: “The rods help solve the problem of supply chains in galaxies, and just as we need to bring raw materials from the port to the factories to make new products, the stellar rods serve to transport gas in the central region when the gas turns into new stars at a rate ranging between 10-10 100 times more than the rest of the galaxy.”
Scientists say that the new discovery regarding stellar bars during the early period of the universe will “shake up” the scenarios for the evolution of galaxies.
Jogi stated that there is a new scenario for the evolution of galaxies, which is that the rods accelerated the production of stars in the early ages.
