The Large Hadron Collider is not only a cool particle physics gizmo, it's also a very, very cold one. Indeed, it is the largest cryogenic system in the world and is one of the coldest places on Earth.
To keep them at superconducting temperature, scientists have to cool the LHC's magnets down to 1.9 K (-271.3°C), which is lower than the temperature of outer space (-270.5°C). First, the magnets are cooled to -193.2°C using 10,000 tons of liquid nitrogen. Then 90 tons of liquid helium is used to lower the temperature down to -271.3°C. The whole cooling process takes a few weeks.
I'm sorry, but that's just freaking awesome.
It's 17 miles in diameter, gets stretched by the moon's gravity, and smashes opposed streams of protons into each other at a collision velocity greater than the speed of light.
Geek out!
