Yet another older picture on the APOD website, but one I still like. This is a picture of the Boomerang Nebula, which is now my new favorite nebula over the Rosette Nebula. This is a beautiful, almost symetrical nebula that is also the coldest place known to man. It is just over 1 degree Kelvin above Absolute Zero. This nebula was created by the winds of a aging star that blo at over 600,000 Km per hour. Because of this rapid expansion, the center is incredibly cold. This image was taken by Hubble in 2007 with polarized filters. This constellation spans about one light year across and is 5,000 light years away in the constellation of Centaurus.
