A mysterious excess of far-ultraviolet light seen across the Milky Way could come from the annihilation of clumpy dark matter ...

By studying faint distortions in galaxy shapes across a vast region of sky, scientists probed the hidden structure of the universe. In the standard picture of the universe, nearly everything is hidden ...

What is dark energy? Why does dark energy seem to be weakening? Is our universe part of a larger multiverse? What lies beyond the boundary of a black hole? The universe seems to be rotating, and if ...

In the leading model of cosmology, most of the universe is invisible: a combined 95% is made of dark matter and dark energy.

Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the accelerating expansion of the universe. However, one competing theory known ...

NEW YORK (AP) — Distant, ancient galaxies are giving scientists more hints that a mysterious force called dark energy may not be what they thought. Astronomers know that the universe is being pushed ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

The universe's expansion may be accelerating faster than previously thought. Dark energy, a mysterious force, might not be constant but could be changing over time. Multiple independent studies show ...

A recent study by Rajendra Gupta, published in "Galaxies," proposes that cosmic phenomena conventionally ascribed to dark matter and dark energy can be explained by the temporal weakening of ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...
