Researchers have captured an extremely rare image of a cosmic filament connecting two galaxies when the universe was just two billion years old.

Astronomers have been able to image gas as it travels down a 3 million light-year-long cosmic highway between two growing galaxies ensnared in the cosmic web.

After hundreds of hours of observations, researchers captured a highly detailed image of a long filament of the "cosmic web" connecting two distant galaxies. The discovery opens new windows for understanding how structures form and evolve in the universe.

Scientists have captured the most detailed image of a cosmic filament which could lead to a better understanding of galaxy formation
