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

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 ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

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 novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. White diamond symbols mark the locations of 20 of the 83 newfound young, low-mass galaxies ...

The local universe may be expanding more slowly than previously thought, scientists have found. The discovery, made in two ...

An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be straightforward. Objects are still emitting light, and that light takes time to travel ...

For decades, we have been taught that the universe is expanding faster and faster. That belief has influenced our view of distant galaxies, how cosmologists have built their theories, and how ...

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to be true. Space is stretching faster today than in the past, and the precise ...

Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those ...

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 ...
