By studying how light from eight distant quasars is gravitationally lensed as it propagates towards Earth, astronomers have ...

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

One of the most stubborn issues in cosmology today concerns the universe's rate of expansion. Scientists know it's expanding, ...

A Simon Fraser University cosmologist believes his team's new research may bring them a step closer to cracking one of ...

New research suggests that a troubling disparity in the rate of expansion of the universe, known as the Hubble constant, may arise from the fact Earth sits in a vast underdense region of the cosmos.

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 ...

IT IS ONE of the biggest mysteries in cosmology—and getting bigger all the time. Ever since Edwin Hubble, an American astronomer, published observations of distant galaxies in 1929, scientists have ...

We have known for almost a century that the universe is expanding, but it's been surprisingly hard to nail down the rate of expansion. The availability of the James Webb Space Telescope is finally ...

Hubble’s measurements of today’s expansion rate do not match the rate that was expected based on how the Universe appeared shortly after the Big Bang over 13 billion years ago. Using new data from the ...

The James Webb Space Telescope has captured some bizarre imagery of an exploding star that, for some reason, kept repeating itself. In a press release, NASA said that new Webb images of what ...

Astronomers have used a new method to confirm a discrepancy between the expansion rate of the early and nearby universe. The ...
