The Hubble constant is a unit that describes how fast the universe is expanding at different distances from a particular point in space. It is one of the keystones in our understanding of the universe ...

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

The universe has been expanding ever since the Big Bang. But there is a problem. We don't know exactly how fast it is expanding because there are tiny discrepancies in one of the most fundamental and ...

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 ...

A striking reality faces modern cosmology: two of the most advanced telescopes ever built now agree on a result that the standard cosmological model cannot explain. Webb’s confirmation of the Hubble ...

Vesto Slipher first observed that galaxies are moving away from us. Edwin Hubble later showed a relationship between galaxy distance and speed. Hubble's work relied heavily on Slipher's earlier data.

A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA's Chandra X-ray Observatory. This new value ...

The term "Hubble constant" is debated, with some advocating for "parameter" due to its variability. Measurements of the Hubble constant are continually refined, yielding greater precision.

The Hubble Constant is the unit of measurement used to describe the expansion of the universe. The cosmos has been getting bigger since the Big Bang kick-started the growth about 13.82 billion years ...

The Hubble constant is one of the most important numbers in cosmology because it tells us how fast the universe is expanding, which can be used to determine the age of the universe and its history. It ...
