Astronomers have identified the coldest place ever detected in space. It is the gas blown away from a star in the latter stages of its life-cycle.

The so-called Boomerang Nebula, one of the youngest of its kind, has been observed in minute detail by the Hubble Space Telescope (HST).

It seems that the central dying star has been expelling gas at such a rate that it has cooled as it expanded to such a degree that it is even colder than the cosmic background radiation that bathes all of space.
