Modern cosmology assumes dark matter exists. But what makes us so certain that dark matter is the answer—and what if we're wrong? Reading time 8 minutes A huge chunk of the universe is missing. It’s ...

For decades, dark matter has been treated as the unseen framework around which galaxies take shape. Even the smallest ...

We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters. Yale astrophysicist Priyamvada Natarajan, a leading theorist on the nature ...

Researchers have been looking at everything, including supernovas, trying to uncover the mysteries of dark matter. Recent scientific studies suggest that dark matter might not be a particle hiding in ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

Researchers using new simulations suggest that the Milky Way’s past collisions may have reshaped its dark matter core. This distorted structure could naturally explain the puzzling gamma-ray glow long ...

An observatory in Chile is taking a timelapse of the sky over the Southern Hemisphere to help scientists measure the ...

After decades of hunting, physicists still don’t know what makes up most of the universe’s matter. Now they need to cast a wider net.

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark ...

A new kind of dark matter could help explain some of the universe’s mysteries, a new study suggests. The study proposes that there are dense clumps of “self-interacting dark matter”, or SIDM, each ...

Dark centre? A simulated version of the Milky Way galaxy. (Courtesy: AIP/ A. Khalatyan) Astronomers have long puzzled over the cause of a mysterious “glow” of very high energy gamma radiation ...
