Dark matter may consist of two particles, explaining why only the Milky Way shows a strange gamma-ray signal while smaller ...

Add Yahoo as a preferred source to see more of our stories on Google. Astronomers have to use indirect evidence, like the explosions of Type Ia supernovae, to investigate the impacts of dark energy.

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

Published in Physical Review Letters, the study proposes that dense clumps of self-interacting dark matter (SIDM) — each ...

Learn how a two-state model of dark matter could explain why gamma-ray signals appear in some galaxies but not others.

For decades, astronomers have believed that dark matter and dark energy make up most of the universe, however, a new study suggests they might not exist at all. Instead, what we perceive as dark ...

Physicists call it “ dark matter, ” a substance they describe as the cosmic glue, the scaffolding, a web that uses gravity to corral, shape and hold together stars, planets and galaxies. Yet nobody ...

A team of cosmologists in China has introduced a mathematical framework that investigates two of the deepest mysteries in cosmology at the same time. Publishing their research in The Astrophysical ...

The Milky Way’s center glows with an unexplained surplus of gamma rays. Smaller galaxies orbiting nearby do not. That ...

When it comes to understanding the universe, what we know is only a sliver of the whole picture. Dark matter and dark energy make up about 95% of the universe, leaving only 5% "ordinary matter," or ...
