A recent study of an international group of scientists has helped to identify an incredibly ancient galaxy, which in its structure is very similar to our native Milky Way. This discovery, published in Nature, was amazed by scientists, as it was still thought that such galaxies existed during the "youth" of the universe.
The study revealed the distant formation of the CEers-2112 using the near-infrared range of space telescope James Webb. Although at first the image seemed only a foggy spot, further examinations revealed it as an ancient galaxy, which has a complex spiral structure, similar to the Milky Way.
Scientists believed that complex forms of galaxies took a long time to form. However, the researchers enriched with information from CEers-2112, the researchers have suggested that within 2 billion years after the Big Bang the Galaxy could look like the one they are watching.
This discovery contradicts previously accepted ideas about the formation of galaxies and their evolution, calling into question the theory that argued that complex forms similar to the Milky Way, emerged only about 8 billion years ago.
This discovery is combined with other unexpected discoveries concerning the conditions of the early universe, the glow of some galaxies is too bright or the growth of black holes is too fast. All this raises new issues and requires revision of our theories concerning the formation of galaxies.
Scientists are trying to explain these and similar phenomena to better understand the emergence and evolution of the universe they work on to build an even more complete picture of the world in which we exist.
