Cuore: The Coldest Heart in the Known Universe

For a period of 15 days, a cooled copper mass at -273.144 degrees Celsius may very well have been the coldest object in the Universe.

The CUORE collaboration at the INFN Gran Sasso National Laboratory has set a world record by cooling a copper vessel with the volume of a cubic meter to a temperature of 6 milliKelvins: it is the first experiment ever to cool a mass and a volume of this size to a temperature this close to absolute zero (0 Kelvin). The cooled copper mass, weighing approx. 400 kg, was the coldest cubic meter in the universe for over 15 days. (Credit: IFN)
