NASA’s James Webb Space Telescope has found strong gravitational lensing in a galaxy cluster about 10.4 billion light-years ...

Our ideas about the universe are based on a century-old simplification known as the cosmological principle. It suggests that when averaged on large scales, the Cosmos is homogeneous and matter is ...

The Big Bang explains a great deal, but some of its deepest questions remain unanswered. Future discoveries could change far more of the story than many people realize.

Physicists sometimes come up with crazy stories that sound like science fiction. Some turn out to be true, like how the curvature of space and time described by Einstein was eventually borne out by ...

Kanazawa, Japan - The expansion of the Universe has occupied the minds of astronomers and astrophysicists for decades. Among the cosmological models that have been suggested over the years, Lambda ...

For many years, the simplest view of dark energy has been that it remains unchanged. Throughout cosmic history, the ...

The cosmological constant Λ, and its generalization as dark energy, makes up roughly 70% of the present-epoch Universe and has been part of the dominant ΛCDM cosmological paradigm for more than a ...

Add Yahoo as a preferred source to see more of our stories on Google. DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every ...

An international team of astronomers has determined that Centaurus A, a massive elliptical galaxy 13 million light-years from Earth, is accompanied by a number of dwarf satellite galaxies orbiting the ...

Cosmological models with varying fundamental constants explore the possibility that quantities traditionally regarded as immutable—such as the speed of light (c), Newton’s gravitational constant (G) ...
