JWST Finds 13M Light-Year 'Cosmic Vine'
Summary
The Josh Universe - Space Discord Server announced a significant discovery by the JWST: a 13-million-light-year-long "Cosmic Vine" of 20 galaxies in the early universe. This ancient structure, embedded in a dark matter filament, is important because it reveals how massive galaxies and clusters formed, showing quiescent galaxies existed much earlier than previously theorized. This finding helps scientists better understand the formation of the universe's largest structures within the cosmic web....

The "Cosmic Vine" is a massive, 13-million-light-year-long chain of 20 galaxies discovered by NASA's James Webb Space Telescope (JWST) in late 2023, located in the early universe (when the universe was just over 1.5 billion years old).
This ancient structure, existing within a dark matter filament, is crucial for understanding how large galaxies and galaxy clusters form, showing massive, star-formation-stopped (quiescent) galaxies even in the early cosmos, challenging previous theories.
It's a key component of the larger cosmic web, revealing how gravity built the universe's largest structures.
