WHAT DOES THE SEARCH FOR DARK MATTER LOOK LIKE?

The DarkSide experiment, designed for the direct detection of dark-matter particles, is located at the Gran Sasso Laboratory in central Italy. It aims to detect weakly interacting massive particles (WIMPs), a leading candidate to explain dark matter, as they pass through super-pure argon.

When the experiment is running, these bug-eyed light detectors point inwards, poised to join the global hunt for the universe’s missing matter. The sphere shown here will house a canister filled with 50kg of liquid argon. If a WIMP hits an argon nucleus, the nucleus recoils and produces a telltale flash of light.
