Italian scientists have discovered a galaxy, which has been 3 billion light years away and has almost unchanged for 7 billion years. This structure, called Kids J0842+0059, is one of the rare examples known as “fossil galaxy” in the world of astronomy.
Fossil galaxies are defined as celestial bodies that form a stars quickly in the early stages of the universe, but then remain in isolated way with other galaxies. Thanks to these features, they offer important information about the formation of the universe.
Two -stage formation process
According to scientists, giant galaxies usually occur in two stages. In the first stage, the stars are born very quickly and the galaxy becomes a very busy, small structure. In the second stage, the merger with the surrounding galaxies begin and the structure is growing. However, fossil galaxies hardly experience this second phase.
According to CNN International; Kids J0842+0059 was formed in the youth of the universe and then did not experience any merger. Researchers, 99.5 percent of the stars of the galaxy occurred at a very early period, he says.
A world full of star
Such galaxies contain billions of sun -like stars. However, the formation of the new star is almost completely stopped. Because of their busy structures, it can be difficult to find multi -planetary systems similar to ours in these galaxies.
One of the leaders of the research. Chiara Spinello estimates that such galaxies are present in the universe “million in a million”. The first traces of Kids J0842+0059 were reached in 2018 with the VLT telescope in Chile. The definitive definition was possible thanks to high -resolution observations made with large binocular telescope in Arizona.
New telescopes will reveal new fossils
The Euclid telescope, launched by the European Space Agency in 2023, will collect information about dark matter and energy and will make it easier to detect fossil galaxies. Scientists think that more fossil galaxy can be found with this telescope.
Professor of Oxford University. “These galaxies are invaluable sources to understand what was happening in the early stages of the universe, Mic says Michele Cappellari.
