Several searches for dark matter particles have been conducted at SNOLAB, a Canadian facility located in a mine near Sudbury, Ont., where the overlying rock shields sensitive detectors from cosmic ...

If whatever particles make up dark matter do self-interact by colliding, and possibly even annihilating one another, new research suggests that clusters of galaxies could be used as natural dark ...

Figuring out the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world’s most sensitive ...

The next generation of dark matter detector, beyond XENONnT and PandaX-4T, should still be able to search for dark matter. But further improvement will start to become difficult.

An interdisciplinary team of researchers is working to lure a hypothesized particle from outer space to the Sanford Underground Research Facility, housed in a former gold mine that operated at the ...

Science has found its first candidate for a dark-matter detector. It’s a really old rock - Dark matter is a mysterious, invisible substance makes up more than 80 percent of all matter in the ...

Dark matter, a type of matter that does not emit, absorb, or reflect light, is predicted to account for most of the ...

When a dark matter particle hits the crystals, it deposits a small amount of energy. The crystals must be kept at extremely low temperatures to reduce thermal noise and must operate at nearly ...

More dark matter detectors Besides COUPP, two other dark matter experiments are running at SNOLAB: The Picasso project, involving researchers from Canada, the U.S. and the Czech Republic, uses a ...

And by running the two detectors at the same time, anytime a signal is seen in the neutron detector, any signal seen simultaneously in the dark-matter detector can be safely ignored.

The experiments Dark matter experiments at SNOLAB – and other international facilities – involve “placing ordinary matter in a detector,” says Dr. McDonald. “The idea is to observe dark ...

Particle accelerators like the Large Hadron Collider have failed to turn up potential dark matter candidates, but could galaxy cluster smashes be used as cosmic dark matter colliders?
