Researchers from the University of Waterloo have proposed a new method to measure the Hubble constant that could help resolve one of modern cosmology's pressing puzzles: the Hubble tension. The study ...

Earth, its cosmic home the Milky Way, and even the very local region of universe around us could be situated within a void of low density compared to the rest of the universe. If so, that would solve ...

New gravitational lensing measurements by the TDCOSMO Collaboration support the Hubble Tension, confirming differences between Early and Late Universe Hubble Constant values using updated ...

Current physics is speeding toward a breaking point, as astronomers confirm that the Hubble tension in new 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.

Last time I wrote about new data that overturns the standard cosmological model. Before anyone starts dusting off their fringe cosmological models, we should note what this new study doesn't overturn.

Astronomers have proposed a new way to solve the so-called “Hubble tension,” but the approach ultimately raises more questions than it answers. By way of background, cosmologists are in a bit of a ...

A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA’s Chandra X-ray Observatory. This new value ...

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.

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 ...
