                        Astronomy Picture of the Day

    Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   Explanation: Laser guide stars and adaptive optics sharpened this
   stunning ground-based image of stellar jets from the Gemini South
   Observatory, Chilean Andes, planet Earth. These twin outflows of MHO
   2147 are from a young star in formation. It lies toward the central
   Milky Way and the boundary of the constellations Sagittarius and
   Ophiuchus at an estimated distance of some 10,000 light-years. At
   center, the star itself is obscured by a dense region of cold dust. But
   the infrared image still traces the sinuous jets across a frame that
   would span about 5 light-years at the system's estimated distance.
   Driven outward by the young rotating star, the apparent wandering
   direction of the jets is likely due to precession. Part of a multiple
   star system, the young star's rotational axis would slowly precess or
   wobble like a top under the gravitation influence of its nearby
   companions.
