It gets its name from UChicago alum Edwin Hubble, who was first to calculate the constant from his measurements of stars in 1929. Despite nearly a hundred years of astronomical measurements and ...

Alongside Snoop Dogg and Demi Moore, a Chicago professor and astronomist was named one of Time Magazine's 100 Influential People of 2025.Wendy Freedman is a professor of astronomy and astrophysics at ...

But he had no way to measure the distances to these reddish ... kilometers/second per light year of distance, now called Hubble's constant. The numbers were not exactly right, and refinements ...

A slowly spinning universe could resolve a puzzle in physics known as the Hubble tension, a new model suggests.

An intriguing new study suggests that the universe may rotate once every 500 billion years. If correct, the authors believe that it could explain one of the most annoying puzzles in astronomic ...

The Hubble constant is the unit of measurement used to describe the expansion of the universe. It relates distances in the universe to the redshifts of galaxies, that is, the amount of stretching ...

Measurements in the comparatively nearby ... At the same time, it could explain the persistent discrepancy in the Hubble constant. However, the model would have to be further developed to verify ...

Istvan Szapudi suggests this cosmic spin could explain inconsistencies in expansion measurements. A mathematical model shows promising results. It calculates a consistent Hubble constant with ...
