The Sudbury Neutrino Detector
The Sudbury Neutrino Detector is an underground observatory designed to detect neutrinos, tiny particles produced by the Sun and other cosmic sources. Located over a mile beneath the Earth's surface in a former nickel mine, it helps scientists understand the Sun's interior and fundamental particle physics. The detector uses a large sphere filled with heavy water, which allows it to observe different types of neutrinos.

Prints are coming soon. The card is free to save and share in the meantime.
