A group of scientists discovered in the Universe the galaxy with the oldest spiral structure, which formed 1.4 billion years after the Big Bang.
According to the website of the ALMA observatory, which uses a complex of radio telescopes in the Chilean Atacama Desert, such a discovery was made by experts from the ALMA Observatory, which uses a complex of radio telescopes in the Chilean Atacama Desert. They named this galaxy BRI 1335-0417.
Scientists estimate the galaxy is 15,000 light-years old from the center of the galaxy (about a third the size of the Milky Way), and the estimated total mass of stars and interstellar medium is also comparable to that of the Milky Way.
It is noted that BRI 1335-0417 contains a large amount of dust, obscuring the light of the stars, which made it difficult to observe it. However, with the help of powerful ALMA telescopes, specialists were able to discern the structure of a distant galaxy.
According to SOKENDAI graduate student and lead author of the study, Takafumi Tsukui, he was thrilled because he hadn’t seen so much clear evidence of a rotating disk, spiral structure, and centralized mass structure in a distant galaxy.
“BRI 1335-0417 is a very distant object, we will not be able to see the true edge of the galaxy. For a galaxy that existed in the early Universe, the size of BRI 1335-0417 was gigantic, ”the scientist explained.
The researchers hope that the study of this galaxy will help understand the formation of galaxies, including the solar system.
