Astronomers have uncovered a hidden cosmic web of galaxies and gas by mapping hydrogen light from the early universe.

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

Where are the smallest galaxies? A recent study suggests that there may not be as nearly as many of them in the early universe as there should be, which has big implications for the story of how our ...

The discovery made by a large research team challenges the existing models of the universe.

Astronomers have unveiled one of the most ambitious maps yet of the early universe, revealing a vast "sea of light" between ...

New 3D map of the early universe from HETDEX reveals faint hydrogen light linking galaxies 9 to 11 billion years ago.

Astronomers have uncovered a hidden population of dusty galaxies that formed just one billion years after the Big Bang, offering a new glimpse into the universe’s formative years. An international ...

When you look up at the night sky, it appears unchanging. But if you look deep enough you will find that the sky is in fact constantly shifting. Satellites, asteroids and interstellar objects pass by.

Researchers suggest the universe's background radiation has been overestimated, potentially challenging the standard model of cosmology and our understanding of early galaxy formation. Space, time and ...

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 ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...
