Galaxy filaments are the largest known structures in the universe containing galaxies with mixed stellar population types and structures. They inject gas into galaxies, helping them grow and evolve.

An international team led by the University of Oxford has identified one of the largest rotating structures ever reported: a "razor-thin" string of galaxies embedded in a giant spinning cosmic ...

The bright source near the bottom of this image, Sagittarius A* – pronounced Sagittarius A-star – is thought to be the location of the supermassive black hole at the center of our home galaxy, the ...

The center of our Galaxy has been intensely studied for many years, but it still harbors surprises for scientists. A snake-like structure lurking near our galaxy’s supermassive black hole is the ...

If you look at the universe on a big enough scale, the billions of galaxies out there aren’t randomly scattered. Instead, they form a structure made up of galaxies and the gas between them, which are ...

Astronomers have found something that shouldn’t exist, or at least isn’t easy to explain: a cosmic filament 140 million light-years away that’s spinning. Not just the galaxies inside it, mind you. The ...

A colossal cosmic filament, measuring 50 million light-years long, has been discovered spinning in deep space, astonishing astronomers with its scale and movement. The filament, which contains more ...

Astronomers using the NASA/ESA Hubble Space Telescope have studied a giant filament of dark matter in 3-D for the first time. Extending 60 million light-years from one of the most massive galaxy ...
