In the last decades, our understanding of the Universe has made tremendous progress. Not long ago, “precision astronomy” was thought to be an oxymoron. Nowadays, satellite experiments and powerful ...

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.

In recent years, cosmologists have been faced with a crisis: The universe is expanding, but no one can agree on how fast it's moving away from us. That's because different ways of measuring the Hubble ...

Astronomers have proposed a new way to solve the so-called “Hubble tension,” but the approach ultimately raises more questions than it answers. By way of background, cosmologists are in a bit of a ...

Using known distances of 50 galaxies from Earth to refine calculations in Hubble's constant, astronomers estimates the age of the universe at 12.6 billion years. Using known distances of 50 galaxies ...

The universe is constantly expanding, and that expansion is accelerating, but we aren’t sure exactly how quickly. Two sets of measurements to estimate the rate of expansion conflict with one another, ...

This illustration shows the three basic steps astronomers use to calculate how fast the universe expands over time, a value called the Hubble constant. All the steps involve building a strong "cosmic ...

The question of how fast the universe is expanding continues to confound scientists. Although it might seem like a fairly straightforward issue, the reality is that it has been perplexing the best ...

A meandering trek taken by light from a remote supernova in the constellation Cetus may help researchers pin down how fast the universe expands — in another couple of decades. About 10 billion years ...

More than 90 years ago, astronomer Edwin Hubble observed the first hint of the rate at which the universe expands, called the Hubble constant. More than 90 years ago, astronomer Edwin Hubble observed ...
