Hubble tension reveals discrepancies in cosmic expansion rates, leading to investigations of rotating universes and their ...

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 ...

Astrophysicists propose a new “stochastic siren” method using the gravitational-wave background from black hole mergers to ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in ...

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.
