"Unveiling the Frigid Depths: Exploring the Coldest Corner of the Universe"
Originally Published 2 years ago — by IFLScience
The coldest natural place in the universe is the Boomerang Nebula, with a temperature of just 1 K (-458°F). It absorbs energy from the cosmic background radiation instead of emitting it like a star's neighborhood normally would. The nebula is expanding rapidly, possibly due to the gravitational interaction between two stars. While there may be colder nebulae in the universe, the Boomerang Nebula is already starting to warm up. Additionally, the existence of temperatures below absolute zero has been predicted, but it is debatable whether they should be considered as true temperatures.
