In 2025, astronomers found one of the largest spinning structures ever reported in the universe: a cosmic filament roughly 50 million light-years long, containing nearly 300 galaxies. Many of its galaxies appear to rotate in sync with the filament itself — a vast, coordinated motion that challenges current models of how galaxies gain their spin.
