All the tools for measuring it in the local, recent Universe give fairly consistent results, around 72 to 74 kilometers per ...

Today scientists rely on two methods. The first is late-universe observation (or observation of the universe as we see it ...

One issue is that when scientists calculate what the Hubble constant should be, it doesn’t quite match observations of the ...

The universe is expanding, and physicists cannot agree on how fast. In a preprint posted in late May 2026, the H0 Distance ...

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

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

Spread the loveThe expansion of the universe has been a cornerstone of modern cosmology, raising profound questions about the nature of reality itself. For decades, scientists have sought to determine ...

New measurement deepens Hubble Tension, suggesting the Universe may be expanding faster and hinting at unknown physics.

Spread the loveThe cosmos is a realm of awe and wonder, yet its expansion poses one of the most perplexing challenges in modern astronomy. Recent findings from an international team of astronomers, ...

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 ...

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

One of the most stubborn issues in cosmology today concerns the universe's rate of expansion. Scientists know it's expanding, but defining the rate of that expansion is challenging. The rate of ...
