NEW YORK, BRONX (ORDO News) — NASA‘s James Webb Space Telescope (JWST) has discovered a galaxy that is a twin of the Milky Way, but with the main difference – its age is only 15 percent of the current age of the Universe.
The galaxy, named ceers-2112, is a spiral galaxy with a band of stars and gas at its center, similar to our Milky Way. However, despite its external similarity, it is the most distant galaxy ever observed.
Interestingly, ceers-2112 casts doubt on existing ideas about galaxy formation. Spiral galaxies with bands similar to the Milky Way are thought to appear only late in the evolution of the Universe. However, the new discovery raises questions about how galaxies form and how they change over time.
The discovery of ceers-2112 was made possible by the advanced technology of the James Webb Space Telescope, which is capable of capturing more light and detail than the Hubble Space Telescope. The galaxy is so far away that it took 11.7 billion years for its light to reach us.
The researchers who discovered ceers-2112 emphasize that its existence changes our understanding of dark matter, a mysterious substance that plays a crucial role in the formation of galaxies. Contrary to popular belief, the ceers-2112 band consists mostly of ordinary matter rather than dark matter, raising questions about the role of dark matter in the early stages of the Universe.
One of the key differences with ceers-2112 is the presence of a band that challenges existing theoretical models. According to the study, it is difficult to reproduce similar structures in the early eras of the Universe, raising questions about what components are physically missing from current models.
The researchers emphasize that understanding the structures of galaxies located at vast distances from each other is key to elucidating the history of their formation. Astronomers intend to continue studying the structures of the first galaxies over the next 5-10 years.
