An international team of astronomers led by specialists from the University of Cambridge in the UK has discovered the oldest galaxy ever observed. According to scientists, it originated more than 13 billion years ago, when the Universe was only 700 million years old. The study was published in the scientific journal Nature. The galaxy was discovered by the James Webb Space Telescope. After observations, astronomers came to the conclusion that star formation processes in the system had long ceased. Astronomers believe that the birth of new stars stopped due to many different factors that deprived the galaxy of accumulations of gas. This could be due to the activity of a supermassive black hole or other reasons. Thus, scientists believe, this may mean the transition of the galaxy from the star formation phase to the stage of rest or extinction. Since the galaxy is located very far from Earth, astronomers observed it as it was 13 billion years ago. Therefore, over the intervening eons, the system could have returned to life and begun to form stars again. Or disappear completely, reports Nature. In addition, scientists have found out what became the first source of light in the newborn Universe. According to data from the Hubble and James Webb Space Telescopes, dwarf galaxies illuminated dark space after the Big Bang. Then, astronomers say, space filled with a hot, dense fog of ionized plasma. Read more about light at the beginning of time in the material from Evening Moscow.
