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.

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's ...

For decades, the cosmological field was working under the assumption that, after the universe began in a hot dense soup of energy that expanded in the Big Bang, it continued to expand, forming the ...

Recent measurements from JWST have confirmed the validity of the “Hubble tension.” The Hubble tension stems from the fact that measuring the Hubble constant—the rate of the universe’s expansion—two ...

Birthed from the minds of astronomers Edwin Hubble and Milton Humason, the Hubble constant has long been our closest attempt at understanding the universe's rate of expansion. However, recent attempts ...

The rate at which the universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos. However, a persistent ...

Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth. To astronomers, the ...

The Universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous -- and highly debated -- results had shown: The Universe is expanding faster than predicted by ...

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.
