From stars and galaxies to colossal filaments stretching billions of light years, this journey explores the largest known structures in the observable universe. Along the way, it reveals enormous ...

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 ...

The rate at which large cosmic structures grow is slower than Einstein’s Theory of General Relativity predicts, report researchers. They also show that as dark energy accelerates the universe’s global ...

Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?

South Africa’s MeerKAT radio telescope has uncovered 60 entirely new cosmic structures previously invisible to scientists. This remarkable achievement marks a leap forward in astronomical research, ...

Add Yahoo as a preferred source to see more of our stories on Google. For decades, our best models of the universe have suggested that a third of the baryonic matter that should be out there in the ...

Reading time: 2 minutes Galaxy motions converge into colored basins of attraction. The Milky Way is shown as the red dot. A team of international researchers guided by astronomers at University of ...

As the universe evolves, scientists expect large cosmic structures to grow at a certain rate: dense regions such as galaxy clusters would grow denser, while the void of space would grow emptier. But ...

A giant cosmic mystery just got bigger. Astronomers have spotted the most distant and most powerful "odd radio circle" (ORC) ever recorded, deepening the puzzle of these rare celestial rings. ORCs ...

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 ...
