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 ...

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 ...

Astronomers have made a new measurement of how fast the universe is expanding, using an entirely different kind of star than previous endeavors. The revised measurement falls in the center of a hotly ...

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.

Astronomers have made new measurements of the Hubble Constant, a measure of how quickly the Universe is expanding, by combining data from the Hubble Space Telescope and the James Webb Space Telescope.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The Universe is an enormous place, filled with stars and galaxies for ...

There’s a big debate in cosmology about how fast the universe is currently expanding. The collision of two neutron stars in 2017, seen in an artist's rendering, created both gravitational waves and ...

A meandering trek taken by light from a remote supernova in the constellation Cetus may help researchers pin down how fast the universe expands — in another couple of decades. About 10 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 ...
