   Explanation: [7]This exciting and unfamiliar view of the Orion Nebula
   is a visualization based on [8]astronomical data and movie rendering
   techniques. Up close and personal with a famous stellar nursery
   [9]normally seen from 1,500 light-years away, the digitally modeled
   frame transitions from a visible light representation based on Hubble
   data on the left to infrared data from the Spitzer Space Telescope on
   the right. The perspective at the center looks along a valley over a
   light-year wide, in the wall of the region's giant molecular cloud.
   Orion's valley ends in a cavity carved by the energetic winds and
   radiation of the massive central stars of the [10]Trapezium star
   cluster. The single frame is part of a multiwavelength,
   three-dimensional video that lets the viewer experience an immersive,
   [11]three minute flight through the Great Nebula of Orion.
