Its light has travelled for <strong>13.4 billion years<\/strong> before reaching us, offering an extraordinary window into the early stages of galactic formation.<\/p>\n\n\n\n<p>The discovery, published in <em>Astronomy and Astrophysics<\/em> and forthcoming in <em>The Astrophysical Journal<\/em>, is the result of the work of two international research groups. The first, led by the Italian <strong>Stefano Carniani<\/strong> of the Scuola Normale Superiore in Pisa, and the second, led by the Netherlands, with <strong>Sander Schouws<\/strong> of Leiden University, used the powerful radio telescope <strong>ALMA<\/strong> (Atacama Large Millimetre\/submillimetre Array) to unravel a cosmic mystery.<\/p>\n\n\n\n<p><strong>A surprisingly mature galaxy in the early universe<\/strong><\/p>\n\n\n\n<p>\u201cThese results have opened up a new perspective on the evolution of galaxies,\u201d says Carniani. \u201cDiscovering such an evolved galaxy in such a remote era is like finding a teenager in a nursery full of babies. This means that its formation took place much more quickly than we thought.\u201d<\/p>\n\n\n\n<p>Newborn galaxies mainly contain hydrogen and helium, while heavier elements such as oxygen form over time. However, <strong>JADES-GS-z14-0 has 10 times more oxygen than predicted<\/strong>, suggesting that its evolution has been incredibly rapid.<\/p>\n\n\n\n<p><strong>Ultra-precise measurements and new challenges for cosmology<\/strong><\/p>\n\n\n\n<p>Thanks to the data collected by <strong>ALMA<\/strong>, researchers measured the distance to the galaxy with unprecedented accuracy, reducing the uncertainty to <strong>only 5 centimetres per kilometre<\/strong>. This level of precision allows us to better understand the growth and evolution of the first galaxies in the universe.<\/p>\n\n\n\n<p>\u201cThis discovery poses a major challenge to cosmological models,\u201d he emphasises. <strong>Andrea Ferrara<\/strong>, coordinator of the Cosmology group at the Normale di Pisa. \u201cWe now have a new benchmark for supercomputer simulations studying the early universe.\u201d<\/p>\n\n\n\n<p>This groundbreaking research could rewrite what we know about the birth of the first galaxies, opening up new avenues for understanding the universe in its earliest moments.<\/p>","protected":false},"excerpt":{"rendered":"<p>Un team di astronomi ha individuato ossigeno nella galassia pi\u00f9 lontana mai scoperta, JADES-GS-z14-0, esistente quando l\u2019universo era ancora giovanissimo.
