The study comes at a critical time, as several next-generation observatories like the Vera C. Rubin Observatory, Nancy Grace ...

A new study has found that a hidden bias in galaxy models can skew gravitational-wave measurements of how fast the universe is expanding. That finding complicates one of astronomy’s most promising ...

A galaxy in the early universe was rich with oxygen, astronomers have found. The discovery raises questions about how early ...

The Andromeda galaxy is surrounded by a constellation of dwarf galaxies that are arranged in a highly lopsided manner. Analysis of cosmological simulations published in Nature Astronomy reveal that ...

A team of cosmologists in China has introduced a mathematical framework that investigates two of the deepest mysteries in ...

JWST observations show that early galaxies were chaotic, gas-filled systems rather than stable disks. Researchers from Cambridge studied over 250 galaxies and found most were turbulent, still forming ...

The local universe may be expanding more slowly than previously thought, a discovery that could relieve a pesky discrepancy ...

The James Webb Space Telescope has revolutionized astronomy in just two years of operations, but how can it see a galaxy 33.8 billion light-years away in a universe that is only 13.8 billion years old ...

Astronomers used subtle warps in galaxy shapes to map the invisible forces shaping the universe. By reanalyzing years of telescope images, they studied more than 100 million galaxies across an ...

The solar system is moving through space over three times as fast as estimated, calling into question our best model of the ...
