Here we see the Alpha Magnetic Spectrometer (AMS) detector.
Most recently upgraded in 2024, it searches for dark-matter signatures from cosmic rays, #antimatter, and missing matter from its position on the exterior of the International Space Station.

Can you guess any of these experiments and what they all have in common?
Hint: they do some heavy detective work😉
