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

In simplest terms, the rate at which the universe expands on paper doesn’t match actual astronomical observations. That speed ...

Learn how Hubble is measuring the expansion rate of the Universe in this new explainer from NASA's Goddard Space Flight ...

In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding?

A new study suggests the universe may rotate -- just extremely slowly. The finding could help solve one of astronomy's biggest puzzles.

One method looks at distant exploding stars or supernovae, to measure the distances to galaxies, and gives an expansion rate for the universe throughout the past few billion years. The other ...

One of astronomy's biggest puzzles may have been solved by a new theory that suggests the universe may rotate at an extremely slow rate. Current models suggest the universe is expanding evenly in ...

After five years of staring unblinking at the sky, the Atacama Cosmology Telescope (ACT) has compiled the most detailed map we've ever seen of the cosmic microwave background – the faint light that ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as "antigravity," undoing the work of gravity, which clumps together matter to build vast ...

Birthed from the minds of astronomers Edwin Hubble and Milton Humason, the Hubble constant has long been our closest attempt at understanding the universe’s rate of expansion. However ...

One such problem, known as the Hubble tension, is a difference in measuring the present-day expansion rate of the universe, a number known as the Hubble constant. Probes of the distant ...
