Huge Fridge Colder Than Outer Space

‘Construction on a cooling system for the world’s biggest science experiment that produces temperatures colder than outer space was completed today.

The mammoth chill factory can generate temperatures as low as 1.9 degrees above absolute zero (-456 degrees Fahrenheit) for the Large Hadron Collider (LHC), a circular particle smasher 17 miles (27 kilometers) wide that is being built at the CERN physics laboratory near Geneva, Switzerland.

The cooling system uses more than 10,000 tons of liquid nitrogen and 130 tons of liquid helium.’
