Astronomers have uncovered a vast, razor-thin strand of galaxies that is not just drifting through space but spinning ...

Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together.

Cosmic filaments are among the largest structures in the Universe, and they rotate. In a new study that stacked thousands of filaments together, they were observed to be rotating along their ...

How does one chart the universe when the entire observable part of it lies hidden behind dust and the glow of distant ...

Hydrogen-rich galaxies are especially useful for tracing how gas flows along filaments into galaxies. By studying them, ...

Comparison of a simulation showing the distribution of hot gas (left), compared with the observed x-ray image of the Abell 3391/95 system (right). Astronomers have stared at the heavens for millennia ...

On a scale that’s hard to fathom, the universe is made up of a “cosmic web” of hydrogen filaments that feed and form galaxies. Now, astronomers have made the first direct observations of light from ...

Dec. 17 (UPI) --Astronomers have discovered a massive intergalactic gas filament measuring at least 50 million light years in length -- the longest yet to be found. Intergalactic filaments are long ...

At the very largest scale, the Universe consists of a "cosmic web" made of enormous, tenuous filaments of gas stretching between gigantic clumps of matter. Or that's what our best models suggest. All ...

Astronomers tracking interstellar comet 3I/ATLAS reveal a far bigger story: a colossal, rotating chain of galaxies that may ...

Smooth filaments stretching for many light-years, seen by the powerful space telescope, could indicate what the right "recipe" is for dark matter.

There are dark places out there in the deep universe, vast Saharas hundreds of millions of light years across, empty except for a stray hydrogen atom or a bit of radiation. They are the cosmic voids, ...
