Gas Plume From a Newborn Star

This Hubble Space Telescope picture shows a hypersonic shock wave (lower right) of material moving at 148,000 miles per hour in the Orion Nebula, a star-forming region 1,500 light-years away. Studies of similar objects infer that such highly supersonic shock waves are formed by a beam of material coming out of newly formed stars. The plume is only 1,500 years old. The image is 112 light-year across. This color photograph is a composite of separate images taken at the wavelengths of the two abundant elements in the nebula: Hydrogen and Oxygen.
