[November 1 AFP] — coldest place ?? in the universe that even an atom will freeze — it is a boomerang nebula (Boomerang Nebula) which is a heavenly body of super-low temperature called 272 Centigrade minus.
The huge radio telescope “Alma (Atacama Large Millimeter/submillimeter Array, ALMA)” in the South America dust アタカマ (Atacama) state newly caught the figure of this nebula the other day.
The temperature of this nebula in Centaurus (Centaurus) about 5000 light year away from ? earth, It is said that it is lower than the temperature of the cosmic background radiation emitted to the universe at the time of having begun to cool after Big Bang (Big Bang) from absolute zero at 1 K (272 Centigrade minus) which is high only only 1 degree.
? boomerang nebula is a comparatively young planetary nebula.
Ionizable gas is emitted from the outer layer of the solar similar star to which a life is invited, and an outline shines.
Energy is used up in the process in which expansion is continued quickly, and a temperature lower than the circumference is maintained by the chilling effect caused as a result.
? Alma telescope is what the organizations of North America, Europe, and Asia cooperated and was installed in the Atacama Desert of dust.
The humidity which becomes the hindrance of astronomical observation, and vegetation are in high ground with an above sea level of 5000 meters which hardly exists.
