   Explanation: [5]Laser guide stars and [6]adaptive optics sharpened this
   stunning ground-based image of stellar jets from the [7]Gemini South
   Observatory, Chilean Andes, planet Earth. These [8]twin outflows of MHO
   2147 are from a young star [9]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.
   [10]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.
