The coldest place in the known universe that happened “naturally” would be in the Boomerang Nebula. This nebula has been found to hit temperatures of “a cosmologically crisp one degree Kelvin.” This roughly converts to -458 degrees Fahrenheit or -272 degrees Celsius.

But NASA labs have simulated much lower temperatures. The most recent record was broken in 2021 with a simulated temperature of 38 picokelvin (pK), or 0.000000000038 of a kelvin, which is the closest we’ve been able to get to absolute zero.
