Launch of the James Webb Space Telescope, the powerful successor to the Hubble Space Telescope. Operating on orbit This allows astronomers to enjoy a period of new discoveries. It is hoped that this will unlock many of the mysteries of the universe or early universe. Now the Webb telescope has observed the first 500 million years after the Big Bang event, which is the theory of the origin of the universe.
Recently, an international team of astronomers revealed in the journal Nature Astronomy that they had observed an early galaxy called Gz9p3 in unprecedented detail, and Babel watched the galaxy Gz9p3 appear as a single point of light. But when the James Webb Space Telescope was used to look again and analyze, it was found that Gz9p3 occurred 510 million years after the Big Bang event, approximately 13 billion years ago.
Astronomers reveal that galaxy Gz9p3 is more massive and mature than expected in the universe's young universe. This means that inside Gz9p3 there must be a rapidly evolving and growing star. It's much more effective than you think. And it's not just big. But Gz9p3's complex shape immediately identified it as one of the oldest galaxy mergers ever discovered, and Gz9p3 suggests that galaxies were able to accumulate mass quickly in the early universe. Through mergers and acquisitions, the efficiency of star formation is higher than expected.
