   Explanation: This exciting and unfamiliar view of the Orion Nebula is a
   visualization based on astronomical data and movie rendering
   techniques. Up close and personal with a famous stellar nursery
   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 Trapezium star cluster.
   The single frame is part of a multiwavelength, three-dimensional video
   that lets the viewer experience an immersive, three minute flight
   through the Great Nebula of Orion.
