The light of a supernova that has traveled for 10 billion years to reach us has given us a new measurement of the Hubble constant – the accelerating rate at which the Universe is expanding. Called SN ...

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 ...

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

The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods ...

The universe’s expansion rate was supposed to be a solved problem, yet the latest high precision map of the early cosmos has pushed one of modern astronomy’s sharpest conflicts back to center stage.

Recent measurements from JWST have confirmed the validity of the “Hubble tension.” The Hubble tension stems from the fact that measuring the Hubble constant—the rate of the universe’s expansion—two ...

The greatest puzzle in cosmology just got even more puzzling. Images from the James Webb Space Telescope have confirmed that the universe appears to be expanding significantly faster than it should be ...

Over the past decade, two very different ways of calculating the rate at which the universe is expanding have come to be at odds, a disagreement dubbed the Hubble tension, after 20th-century ...

The new study used the known distance to a galaxy called M106/NGC 4258 — a spiral galaxy in the constellation Canes Venatici — as a reference point. The universe is expanding faster than astronomers ...

(blue; the yellow dots represent individual galaxies). The Milky Way (green) lies in an area with little matter. The galaxies in the bubble move in the direction of the higher matter densities (red ...
