Large groups of galaxies come together to form clusters, and those clusters are linked together by vast streams of hot gas known as filaments. These intergalactic links reach temperatures well over a ...

This story was updated at 9:32 a.m. EDT on July 5. A giant string of invisible dark matter has been discovered across the universe between a pair of galaxy clusters. The filament forms a bridge ...

Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together. The razor-thin chain of galaxies sits inside a much larger filament that ...

Active galactic nuclei, energetic and luminous regions powered by an accreting supermassive black hole at the center of some galaxies, can launch a jet that drives a gas outflow, shaping star ...

Astronomers have discovered the distant relatives of huge, highly organized magnetic filaments dangling in the center of the Milky Way, a discovery that could help scientists finally explain these ...

ESA’s XMM-Newton X-ray observatory has revealed three massive filaments of hot gas flowing towards a cluster of galaxies, uncovering a portion of the cosmic skeleton that pervades the entire Universe.

Researchers have zoomed in on the area surrounding the supermassive black hole lurking at the center of our galaxy, and made a fascinating discovery: a structure of "strange filaments" driving a cycle ...

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 ...

Behold, the stringy, rainbowesque melange of one-dimensional structures hidden in plain sight across the galactic center. Or should we say plane sight? The tendrils measure 5 to 150 light-years in ...

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 ...

Astronomers have discovered a giant, galaxy-packed filament ablaze with billions of new stars. The filament is the first structure of its kind spied in a critical era of cosmic buildup when colossal ...
