One of the oldest galaxies in the universe, JADES-GS-z11-0, has shocked scientists with its discoveries, as it formed just 400 million years after the Big Bang, when the universe was only three percent of its current age. What’s most interesting, however, is that this galaxy is already rich in oxygen.
The James Webb Space Telescope first discovered this unique object, and the latest detailed studies were carried out using the ALMA system, a combined set of 66 telescopes located in the Atacama Desert in Chile. Studies have shown that the amount of oxygen in the galaxy is about 30 percent of the oxygen in the modern galaxy.
Scientists were also surprised by the rapid development of the galaxy. Every year, new stars are formed there, equal to the mass of about six solar masses, several times more than in our Milky Way. The discovery raises interesting questions: Could life have formed earlier than we think? While the answers to these questions are not yet known, one thing is clear: the universe matured much faster than we thought.
