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.

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

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 ...

A recent study has investigated teleparallel gravity and its potential to resolve tension surrounding the expansion of the universe in a way that general relativity can't. In the early 20th century, ...

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 ...

In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding? Astronomers have tried two main methods to figure it out, but their numbers don’t ...
