Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

Cosmic voids are different. These vast expanses contain very little matter. In such places, the vacuum of space-time itself becomes the dominant component. If you were positioned at the center of a ...

Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward ...

A closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

For decades, the Standard Cosmological Model has operated on a single, foundational assumption: the Big Bang happened everywhere at exactly the same time. Today, a newly released theoretical paper ...

There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on ...

New 2026 research links coffee and tea to lower dementia risk, suggests dark matter may interact with neutrinos, and reveals ...

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

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

For the past two decades, scientists have wondered about a bright, distinct striped pattern seen in radio waves emanating ...
