Astronomers from the University of Arizona have used NASA’s James Webb Space Telescope to discover a 3-million-light-year-long galactic filament from the early universe. The filament, which consists of 10 galaxies, was found just 830 million years after the Big Bang and is anchored by a luminous quasar with a supermassive black hole at its core. The team believes that the structure will eventually evolve into a massive cluster of galaxies. The discovery provides insights into the fundamental architecture of the universe and the formation of supermassive black holes. The findings were published in two papers in The Astrophysical Journal Letters.
