Coldest Place Known in the Universe

The Boomerang Nebula (also called the Bow Tie Nebula) is a protoplanetary nebula located 5,000 light-years away from Earth in the Centaurus constellation. The nebula is measured at 1 K (−272.15 °C/−457.87 °F), the coldest place known in the universe. The Boomerang Nebula was formed from the outflow of gas from a star at its core. The gas is moving outwards at a speed of about 164 km/s and expanding rapidly as it moves out into space. This expansion is the cause of the nebula's very low temperature.

With a temperature of −272 °C, it is only 1 kelvin warmer than absolute zero (the lowest limit for all temperatures). Even the −270 °C background glow from the Big Bang is warmer than this nebula. It is the only object found so far that has a temperature lower than the background radiation.

Pretty cool eh? ;)
