The Boomerang Nebula (Bow-tie Nebula)
The Boomerang Nebula is about 5000 light years away from the Earth, situated in the constellation Centaurus and is the coldest place known in the entire universe at a temperature of 1K. According to the astronomers, the nebula houses a central dying star which has been losing one-thousandth of a solar mass of material from the last 1500 years. The bow-tie shape of the nebula is said to have formed due to very fierce winds (blowing at about 500,000 kmph) blowing the ultra cold gas away from the dying star.
