The largest known structure in the Universe may be even larger than the large we thought it was. A re-examination of the distribution of powerful space explosions suggests that the Hercules-Corona ...

Astronomers have identified what could be the largest structure ever observed in the known universe—a vast network of galaxy clusters and superclusters containing an astonishing 200 quadrillion solar ...

A mysterious ultra-large structure discovered in space may challenge our understanding of the cosmos, according to a new study The structure dubbed the "Big Ring on the Sky" lies around 9.2 billion ...

Astronomers have created an enormous 3D map of the universe revealing a glowing “sea of light” from hydrogen gas during the cosmic dawn nearly 11 billion years ago.

If you thought the cosmic web was tangled enough, think again. A team of astrophysicists recently used gamma-ray bursts—those spectacular, enigmatic explosions of energy from the farthest reaches of ...

The universe's largest structure, the Hercules-Corona Borealis Great Wall, was already a challenge to explain with models of the universe due to its incredibly vast size — and now, using the most ...

A new AI-powered method is changing how scientists measure the universe. Developed by researchers at the Flatiron Institute and their partners, this technique offers a far more accurate way to ...

The universe is peppered with galaxies, which, on large scales, exhibit a filamentary pattern, referred to as the cosmic web. This heterogeneous distribution of cosmic material is in some ways like ...

This image shows five newly discovered superstructures. Quipu (red) is the largest structure ever found in the universe. The others are Shapley (blue), Serpens-Corona Borealis (green), Hercules ...

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. As ...
