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

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.

The rate of the universe’s expansion has vexed astronomers for decades. Called the Hubble constant, the figure is quite different depending on how you get to it—fittingly, a source of constant ...

Astronomers have been arguing about the rate of the universe’s expansion for nearly a century. A new independent method to measure that rate could help cast the deciding vote. For the first time, ...

Using a new framework, astronomers arrived at the most precise measurement of our universe’s expansion rate—but things still don’t add up, they say. Reading time 3 minutes One major, unsolved problem ...

Whatever dark energy is, explanations for it have less wiggle room following a Hubble Space Telescope observation that has refined the measurement of the universe’s ...

Until just a century ago, our galaxy was thought to be the lone family of stars occupying the Cosmos. Philosophers, notably Immanuel Kant in the 18th Century, postulated the existence of other ...

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 ...
