SNOLAB, Canadian neutrino laboratory
SNOLAB is an underground laboratory built within a former nickel and copper mine in Greater Sudbury, Ontario, Canada. The site provides researchers with a space shielded from cosmic radiation, which allows sensitive experiments on neutrinos, dark matter, and other fundamental particles to run without interference.
The original Sudbury Neutrino Observatory was set up in the 1970s after scientists noticed that fewer neutrinos than expected were arriving from the Sun. The finding that neutrinos change form as they travel was confirmed here and earned a Nobel Prize in 2015.
Local businesses in Sudbury have drawn on the lab's work for their own names and products, such as a coffee brand called Dark Matter Coffee and a beer named Cosmic Rays. These names show how the underground science has quietly shaped the way the city sees itself.
The lab is not open to casual visitors, but Science North in Sudbury offers exhibits, virtual tours, and videos that explain the experiments in plain terms. Online events and educational programs are also available for those who want to go deeper into the research.
The rock above the lab blocks nearly all cosmic radiation, making it one of the most shielded research sites on the planet. Scientists from over 20 countries share the facility with an active mine that continues to operate around them.
