The first entry from my Google search tells me that it is the “Boomerang Nebula,” which is 5,000 light-years away and has a temperature of about one Kelvin. However, for me, as a researcher in the field of ultracold quantum gases, the coldest place in the Universe is not in outer-space but on Earth in our laboratories, where we use laser beams, ultraclean vacuum systems, and a host of other technologies to trap and cool atoms to nano-Kelvin temperatures.In this extreme temperature regime, our intuition of how Nature works dramatically breaks down.
