Researchers working with data from the South Pole Telescope have released a major catalog of galaxy clusters, giving ...

Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity.

A new set of cosmological studies is raising questions about one of the deepest assumptions in modern physics: the idea that the universe behaves uniformly on the largest scales. Using supernova ...

A quasar from the universe’s first 850 million years has started to look less like a distant pinprick and more like a real ...

Dark matter is one of the biggest mysteries in science. It cannot be seen directly because it does not emit, absorb, or ...

Astronomers have revealed the sharpest image ever captured of a filament in the cosmic web — the enormous hidden structure connecting galaxies across the Universe. The glowing strand stretches 3 ...

Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental ...

The large-scale structure of the Universe arises from the gravitational amplification of primordial fluctuations, producing a cosmic web of galaxies, filaments, clusters and voids. At sufficiently ...

Diffuse radio emissions captured by the MeerKAT telescope spanning millions of light-years. Visualisation by Konstantinos Kolokythas, CC BY Astronomers are uncovering previously hidden structures ...

The formation of cosmic structures is traditionally modelled through the gravitational collapse of dark matter, yet baryonic components—ordinary matter in the form of gas, stars and dust—exert a ...
