      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.
