This video explores the enigma of dark matter, an elusive substance believed to make up most of the universe's matter. While ...

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. A team had found a small, strange galaxy that appeared to ...

Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

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 ...

The hero is regular matter, which is everything we can see around us. Antimatter is the mirror-image explosive twin that ...

Now scientists think fusion reactors could recreate theoretical dark matter particles, so-called axions, and give researchers a better handle on dark matter’s physical properties and behavior. One of ...

A galaxy made of 99.94% to 99.98% dark matter immediately challenges and updates models for how dark matter works. It also sheds light on how the universe arrived at the large-sca ...

Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

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 ...

This new map is not only the most detailed view of the universe’s invisible scaffolding to date, it also allows astronomers to look deeper into cosmic history. Reading time 3 minutes Dark matter—the ...
