The Lumina Project spans 2 billion years and will allow scientists to test theories and predictions about the origins of the ...

A new simulation offers a highly immersive look at what happened during the first couple of billion years following the Big ...

To help astronomers understand what they are seeing, researchers at the Center for Astrophysics | Harvard & Smithsonian have ...

The Lumina simulation follows galaxies, gas and radiation across the early universe, helping astronomers test how hydrogen ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

A major limit on dark photon dark matter may be far weaker because early-universe plasma stops absorbing energy much sooner ...

Astrophysicists from The University of Hong Kong (HKU), working with a research team led by Beijing Normal University (BNU), have developed a more physically realistic approach to testing how ...

Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like ...
