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 ...

Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight ...

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 ...

(CNN) — The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

The universe is expanding faster than previously thought, according to a team of astronomers using the Hubble Telescope. How much faster? Five to nine percent faster. Initially the expansion of the ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...
