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.

A new study published in the Journal of Cosmology and Astroparticle Physics (JCAP) presents a methodology to test the ...

If scientists confirm an anisotropic expansion, it would challenge the assumption that the universe has no preferred directions.

A unique dataset of Type Ia supernovae being released today could change how cosmologists measure the expansion history of ...

The Vera C. Rubin Observatory is set to revolutionize our understanding of the cosmos by detecting millions of exploding ...

The Universe is expanding faster than predicted by theoretical models, and faster than can be explained by our current understanding of physics. This discrepancy between model and data became ...

The model isn't perfect. It still assumes something about the early universe — namely, that the cosmological constant is strong enough to lead to a rapidly expanding cosmos. And it doesn't ...

"The Hubble tension is now a Hubble crisis." The mystery of the Hubble tension has deepened with the startling finding that the Coma Cluster of galaxies is 38 million light-years closer than it should ...

The Universe is expanding faster than predicted by theoretical models, and faster than can be explained by our current understanding of physics. This discrepancy between model and data became ...

It's all thanks to multi-object spectroscopy, which measures the redshift of these galaxies, and hence the distance to them in an expanding ... to the standard model of cosmology (which describes how ...
