Depending on the value of the Hubble constant, this gives an age of about 14 billion years—not far off the current best-estimate of 13.8 billion years. However, there’s a slight complication. The ...

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

Hubble’s law and the Hubble constant became entrenched among astronomers, while Slipher’s contribution was nearly forgotten. By nature, ...

Astronomers have made new measurements of the Hubble Constant, a measure of how quickly the Universe is expanding, by combining data from the Hubble Space Telescope and the James Webb Space Telescope.

The issue has come to be known as the "Hubble tension."It arises from the fact that there are two ways to calculate the ...

Together with the standard model of cosmology, the images show that the universe is expanding with a Hubble constant that’s lower than the JWST measurement by about 5.6 kilometers per second per ...

New evidence deepens a mystery around the Hubble constant, one of the most important numbers in cosmology. Nearly 200,000 light-years from Earth, the Large Magellanic Cloud—a satellite galaxy of ...

What is the Hubble Constant, and how do we measure it? The rate at which the universe is expanding is expressed as a value called the Hubble Constant, generally abbreviated as “H 0 ”.

The fate of the universe, or at least the Hubble tension, doesn’t just hinge on JWST. Many other facilities will come online in the next few years, providing more evidence for this investigation.

The value of the Hubble constant provided by standard candles is much higher than the value CMB observations have given. This sounds like it should have a simple solution.
