Located 5000 light years from us, this young planetary nebula called the Bow-Tie Nebula or Boomerang Nebula is till now the coldest place ever detected in the universe. It is just one degree warmer than the lowest limit of temperature possible – the absolute zero (-273C). Even the background radiation i.e. the glow of big bang is warmer than this nebula.
This beautiful shape of the nebula can be credited to the central star which is in its last stages of life and is expelling gas in tremendous force hence making these delicate structures in space. The light in this image is basically starlight being reflected by dust particles clicked using a green-yellow filter.
