This brings us a huge leap forward in our understanding of the universe.

A new study has estimated the universe’s possible age by using precise data on stars.

New NASA-level software framework reproduces DUT vs ΛCDM results, resolving Hubble and growth tensions with Δχ² = ...

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.

Whether you call it a vibe shift or a paradigm shift, physicists must be ready to challenge their fundamental understanding ...

A rare total lunar eclipse will turn the Moon a deep coppery red tonight, offering skywatchers a safe and spectacular celestial show.

A team of scientists says it's possible to use tiny ripples in space and time, or gravitational waves, to measure the rate at which our universe is expanding. This could solve one of the biggest ...

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 ...

A subtle gravitational-wave “hum” from merging black holes may help settle the cosmic fight over how fast the universe is ...

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology.

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 ...

A newly discovered jellyfish galaxy, seen as it existed 8.5 billion years ago, is challenging assumptions about conditions in the early universe. Astrophysicists at the University of Waterloo have ide ...
