The rate of cosmic expansion is now known as the Hubble Constant. Ironically ... down the expansion rate precisely, giving the universe an age of 13.8 billion years. This required establishing ...

Determining the expansion rate of the Universe -- known as the Hubble constant -- has been a major scientific pursuit ever since 1929, when Edwin Hubble first discovered that the Universe was ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

"The Hubble tension is now a Hubble crisis." The mystery of the Hubble tension has deepened with the startling finding that the Coma Cluster of galaxies is 38 million light-years closer than it should ...

Hubble's images have helped to pin down the age of the universe, which the expansion rate of pulsating stars suggests is some 13 billion to 14 billion years. Hubble has also captured images of ...

In the 1920s, astronomers thought that the Milky Way was the entire universe. Hubble's discovery revealed a much bigger ...
