For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right ...

A proposed five-satellite Cosmic Positioning System could measure cosmic distances directly and help address discrepancies in the Hubble constant through solar system–scale triangulation.

Pasadena, CA — Ohio State University researchers have found a way to measure distances to objects three times farther away in outer space than previously possible, by extending a common measurement ...

A team of astronomers using NASA’s Hubble Space Telescope has measured the universe’s expansion rate using a technique that is completely independent of any previous method. Knowing the precise value ...

Let’s try a demonstration that we all enjoyed in elementary school. Close one eye, hold out your thumb at arm’s length, and align it with an object on the other side of the room. Without moving your ...

The universe is expanding; we've had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate. The universe is expanding; we've ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.

The gravitational waves emitted by the merger of black holes, when lensed by massive objects as the waves travel toward Earth can be used to calculate the rate at which the universe is expanding Photo ...

(Santa Barbara, Calif.) — The universe is expanding; we’ve had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate. It’s no ...
