anything above absolute zero (-459.67 degrees Fahrenheit or -273.15 degrees Celsius or 0 degrees Kelvin), radiates in the infrared. Absolute zero is the temperature at which all atomic and molecular motion ceases.

Typical noontime temperatures are four degrees Celsius above absolute zero. As temperatures move toward absolute zero, the kinetic energy of the molecules approach a finite value.
A method of producing temperatures close to absolute zero. A sample of a paramagnetic salt is cooled in liquid helium in a strong magnetizing field. The sample is then thermally isolated by pumping away the helium, and the magnetic field is removed.
