Recent surveys hint that the rate of cosmic expansion changes dramatically over time; if that's true, then the universe could ...

Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still don’t add up, they say.

Artist’s interpretation of the cosmic distance ladder — a succession of overlapping methods used to measure distances across the Universe, where each rung of the ladder provides information that can ...

Scientists are on the edge of their seats as they analyze this remarkable new map, not only to better understand the fate of ...

A new synthesis of astronomical measurements confirms a persistent mismatch that could point to physics beyond current models.

The most precise measurement yet shows the Universe is expanding faster than expected, deepening the Hubble tension. The ...

A squad of new AI algorithms called GAME could help astrophysicists take a more accurate reading of the universe’s behavior, ...

For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right now? The expansion rate, called the Hubble constant, ought to come out the ...

A new Utah Valley University study is providing new evidence in a debate astronomers across the world haven’t been able to agree on — how fast the universe is expanding. The findings may add more fuel ...

An international collaboration of astronomers has produced one of the most precise measurements yet of how fast the local Universe is expanding. The ...

A recent study published in Astronomy & Astrophysics has provided the most accurate measurement of the universe’s expansion rate, a discovery that not only refines our understanding of cosmology but ...
