The Roman telescope promises to provide a clearer picture of the large-scale structure of the universe and the forces shaping ...

In a new study published in The Open Journal of Astrophysics, scientists have unveiled a new mapping of the universe’s ...

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 ...

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

NASA’s Roman Space Telescope will study thousands of cosmic voids, mapping galaxy distributions to investigate dark matter, dark energy and the universe’s large-scale structure through precise ...

An artist’s concept of the dark energy-driven accelerating expansion of the universe. New results suggest dark energy’s influence on cosmic expansion has weakened over time. In 2024 a shockwave ...

Recent observational breakthroughs are beginning to challenge the long-standing view of dark energy as unchanging. Data from the Dark Energy Spectroscopic Instrument ( DESI ), an advanced survey ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...

Our universe is filled with galaxies, in all directions as far as our instruments can see. Some researchers estimate that ...

In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery birth like the Big Bang, this idea suggests the cosmos has been growing in ...

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely interact with the rest of the universe via gravity and to serve as the ...

"Dark matter could be captured by stars and accumulate inside them. If that happens, it might also interact with itself and annihilate, releasing energy that heats the star." "Dark dwarfs" may sound ...
