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

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

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

Using data from space telescopes and other instruments, astronomers, cosmologists, and astrophysicists are able to deduce and ...

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

Could the universe be rotating at an imperceptible speed? An extremely slow rotation, occurring once every 500 billion years, ...

But it doesn’t explain the so-called “Hubble tension”—a long-standing disagreement between two ways of measuring how fast the universe is expanding. One method looks at distant exploding ...

Now, people who own a 2025 Neo QLED 8K, 4K, or QLED TV can choose from hundreds of pieces of artwork to display when they’re ...

As it has traveled through the cosmic distances, all those billions of light-years on its way to our eager telescopes, it has experienced the redshift effects of our expanding Universe.

NASA's Hubble Space Telescope shows off an infrared view of the spiral galaxy M51, dubbed the Whirlpool Galaxy. 31,181 people played the daily Crossword recently. Can you solve it faster than ...

None of the currently accepted models of the universe account for any overall spin. Instead, they describe it as expanding uniformly in all directions. However, these models run into trouble with the ...
