Explanation: A cold wind blows from the central star of the Boomerang Nebula. Seen here in a false color image of dust reflected starlight, the nebula lies about 5,000 light-years away. The boomerang shaped cloud appears to have been created by a high-speed wind of gas and dust blowing from an aging central star at speeds of over 300,000 miles per hour. This rapid expansion has cooled the nebular gas to about -458 degrees Fahrenheit or 1 degree above absolute zero, making it the coldest region observed in the distant Universe. The frigid Boomerang nebula represents a unique object for astronomers and is believed to be a star or stellar system evolving toward the planetary nebula phase.
