Is anything colder than space?
Astronomers say the Boomerang Nebula is the coldest known object in the universe. They’ve learned that its temperature is one degree Kelvin (minus 458 degrees Fahrenheit). That’s even colder than the faint afterglow of the Big Bang, which is the natural background temperature of space: colder than space itself.
