The international H0DN Collaboration – a community consensus report on the Hubble constant – has remapped the markers we use ...

A comprehensive new study combines decades of research to reveal that we're missing an essential component in our ...

For the last several years, cosmology – the study of the universe as a whole – has been facing a major tension. The two main ...

When more than a dozen ways of measuring the universe’s expansion all point to the same number, and that number still clashes ...

Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still ...

A major international effort has produced an ultra-precise measurement of the Universe’s expansion rate, confirming it’s ...

The recent observations have helped the scientists to track the growth of the Crab Nebula by comparing images taken decades ...

Not only is the Universe expanding, but its expansion is actually happening at a speed higher than was thought possible until ...

Douglas Adams told us the answer to life, the universe and everything is 42. If only cosmology were so straightforward. Astronomers have been arguing for years about a number every bit as fundamental, ...

A major survey verifies 3,500 gravitational lenses, offering new tools to map dark matter and track cosmic expansion.

To turn that distance into a Hubble constant, you also need the event’s redshift, which is tied to how fast the source is receding due to cosmic expansion. Standard approaches get the redshift by ...

A new analysis has found that the local Universe is expanding faster than predicted from the early Universe, confirming a long-standing mismatch between ...
