The coldest natural spot in the Universe currently is the Boomerang nebula, which resides 5,000 light-years away from us. Its temperature is measured to be 1 Kelvin or -272.15 degrees Celsius. Yet, that still isn’t the coldest temperature we have ever measured.
The coldest temperature was manifested in an underground lab in Italy. The volume represented the coldest cubic meter in the Universe. Researchers of the collaboration Cryogenic Underground Observatory for Rare Events (CUORE) created a refrigerator that cooled at an astounding -273.144 degrees Celsius or 6 milliKelvin. That is nail-bitingly close to Absolute Zero! The researchers maintained the temperature for two weeks to study the behavior of neutrinos – spooky subatomic particles that might hold the secret to the matter that surrounds us.
Is this too cold?
