Created by high-speed winds of gas and dust coming from an aging central star at over 600,000 km per hour, the Boomerang Nebulais a symmetric cloud. The "rapid expansion" has cooled molecules within the nebular gas to one degree above absolute zero, which makes it the coldest known region in the Universe. It is believed that the Boomerang Nebula is a star or stellar system developing into a planetary nebula. Shining with light from the central star reflected by dust, the Boomerang Nebula spans around 1 light-year and lies 5,000 light-years away near the constellation Centaurus. This Hubble Image is pretty amazing, especially how it shows the array of colors.
