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. And it is hoped that this will lead to unlocking many of the mysteries of the universe or the early universe. And 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 have observed an early galaxy called Gz9p3 in unprecedented detail. Bubble has seen the galaxy Gz9p3 appear as a single speck of light. But when using the James Webb Space Telescope to look again and analyze, it was found that Gz9p3 occurred 510 million years after the Big Bang event, or approximately 13 billion years ago.
Astronomers reveal that the galaxy Gz9p3 is more massive and mature than expected in the universe’s young universe. This means that within Gz9p3 there must be a star that is developing and growing quickly. It’s much more effective than you think. And it’s not just big. But Gz9p3’s complex shape also immediately identified it as one of the earliest galaxy mergers ever discovered. Gz9p3 suggests that galaxies were able to accumulate mass quickly in the early universe. through mergers and acquisitions Its star formation efficiency is higher than expected.
