Astronomers using the James Webb Space Telescope (JWST) have made a groundbreaking discovery, finding ten galaxies that make up an early version of the cosmic web just 830 million years after the Universe began. The cosmic web is the large-scale structure of the Universe, consisting of filaments and voids. These filaments and voids formed as density fluctuations in the early Universe.
The ten galaxies were found aligned in a thin, three million light-year-long thread anchored by a bright quasar. This structure surprised the team due to its size and its place in cosmic history. It is one of the earliest filamentary structures associated with a distant quasar ever found.
The discovery was made as part of the ASPIRE program, which aims to understand the formation of the earliest galaxies and the births of the first black holes. The program also seeks to understand how the early Universe was enriched with heavier elements and how it all played out during the epoch of reionization.
Quasars, which are powered by supermassive black holes, played a significant role in the study. At least eight of the quasars in the ASPIRE study have black holes that formed less than a billion years after the Big Bang. These black holes have masses between 600 million to 2 billion times the mass of the Sun. The rapid growth of these black holes raises questions about their formation and the availability of fuel.
The ASPIRE program aims to resolve questions about the feedback between galaxy formation and black hole creation in the early Universe. It also hopes to shed light on the formation and evolution of the cosmic web. Further observations and studies are needed to understand the overdensities in the infant cosmos and the formation of supermassive black holes.
The discovery of these early galaxies and their alignment in the cosmic web provides valuable insights into the origin and evolution of the Universe. It offers a glimpse into the time when the first stars and
How does the discovery of ten galaxies within a thread-like structure in the early Universe contribute to our understanding of the formation and evolution of the cosmic web?
Astronomers have made a groundbreaking discovery using the James Webb Space Telescope (JWST), uncovering ten galaxies that existed just 830 million years after the Universe began. These galaxies are part of an early version of the cosmic web, the large-scale structure of the Universe consisting of filaments and voids. The formation of these filaments and voids occurred as density fluctuations in the early Universe.
The ten galaxies were found arranged in a thin, thread-like structure extending over three million light-years and anchored by a bright quasar. The size and place in cosmic history of this structure surprised the team, as it represents one of the earliest filamentary structures associated with a distant quasar ever discovered.
This discovery was made as part of the ASPIRE program, which aims to understand the formation of the earliest galaxies and the birth of the first black holes. The program also seeks to unravel how the early Universe became enriched with heavier elements and the processes that occurred during the epoch of reionization.
