The Hubble constant is one of the most important numbers in cosmology because it tells us how fast the universe is expanding, which can be used to determine the age of the universe and its history. It ...

"The Hubble tension is now a Hubble crisis." The mystery of the Hubble tension has deepened with the startling finding that ...

Is it possible to understand the universe without understanding the largest structures that reside in it? In principle, not ...

A new study reveals Quipu, a vast network of galaxy clusters and superclusters, being dubbed the largest structure in the known universe.

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

Through the lens of the Hubble and James Webb Space Telescopes, scientists are zeroing in on the Hubble Constant, a vital ...

Largest Discovery: Quipu is the biggest structure found in the Universe. Content: Along with four other superstructures, it holds 45% of galaxy clusters, 30% of galaxies, 25% of matter, and occupies ...

Or, more precisely, astronomers have used multiple methods of estimating the Hubble constant, and the different methods are converging quite tightly on two different values! This clearly can’t ...

The rate of cosmic expansion is now known as the Hubble Constant. Ironically, Hubble himself never fully accepted the runaway universe as an interpretation of the redshift data. He suspected that ...

There's two main tactics for measuring the Hubble constant. One is directly, by observing 'standard candles' — that is, objects with predictable luminosities such as Cepheid variables ...
