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

Two kilometres underground near Sudbury, Ont. , a machine has reached a temperature so low it barely seems real.

Its ratio differs from the Milky Way to dwarf galaxies.

Two kilometers beneath the Canadian Shield, inside a nickel mine turned physics laboratory, a set of silicon and germanium ...

Deep underground in a Canadian mine, a refrigerator nearly 1,000 times colder than outer space has just reached its target temperature—a milestone that brings scientists one step closer to potentially ...

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. It was 2018, and the discovery had just been announced. A team ...

Tohoku University researchers have found a way to make quantum sensors more sensitive by connecting superconducting qubits in optimized network patterns. These networks amplify faint signals possibly ...

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 ...

Dark matter is some kind of substance that has gravity—it holds galaxies together—yet cannot be directly seen with any instrument yet created. We know it’s out there because of the effects it has on ...
