Scientists named the newly discovered galaxy ceers-2112. The discovery raised new questions about scientific theories about the evolution of galaxies, CNN wrote.
Like the Milky Way, ceers-2112 has a spiral structure. At the same time, it is the most distant known galaxy of its kind. Its center is made up of stars. It was probably created shortly after the Big Bang.
The discovery proved to scientists that galaxies similar to the Milky Way were already formed in the early stages of the expansion of the universe. They were particularly surprised by the regular structure of the galaxy, since most of them were very unstable and unstable at this time, the website Space reported.
The Webb Telescope gives astronomers a glimpse into the beginning of the universe and helps understand how galaxies form.
Before this discovery, scientists believed that spiral galaxies like the Milky Way did not form until seven billion years ago. This type of galaxy has specific centers that are made up of regularly rotating stars. Astronomers assumed that stars previously failed to rotate regularly and thus could not form stable centers of galaxies.
According to Alexander de la Vega, a scientist from the University of California, some theories about the formation of galaxies will have to change and take more into account the presence of dark matter that was part of early galaxies.
Dark matter has never been found. Yet they are thought to make up to 85 percent of all matter in the universe. According to scientists, dark matter may have played an important role in the formation of the centers of the first galaxies.
The Webb telescope should help discover other early galaxies in the future. “Research on ceers-2112 will help us discover other galaxies in the early universe,” said de la Vega.
