Scientists have produced the clearest view ever of part of the cosmic web, the enormous hidden network of matter that stretches across the Universe and connects galaxies together. After spending hundreds of hours collecting observations, an international team captured a detailed image of a massive cosmic filament linking two actively forming galaxies from a time when the Universe was only about 2 billion years old.
The discovery offers a rare direct look at one of the largest structures in existence and could help researchers better understand how galaxies grow and evolve over cosmic time.
The Universe's Hidden Structure
Modern cosmology suggests that dark matter makes up roughly 85% of all matter in the Universe. Although invisible, dark matter is believed to shape a gigantic web-like framework made of long filaments. At the points where these filaments intersect, galaxies form and shine brightly.
Scientists think these filaments also act as intergalactic highways, channeling gas into galaxies and fueling the birth of new stars. Learning how this gas moves through the cosmic web is considered essential for understanding how galaxies develop.
