   Explanation: What would it look like to fly into the Orion Nebula?
   [13]The exciting dynamic visualization of the Orion Nebula is based on
   real [14]astronomical data and adept movie rendering techniques. Up
   close and personal with a famous stellar nursery [15]normally seen from
   1,500 light-years away, the digitally modeled representation based is
   based on [16]infrared data from the [17]Spitzer Space Telescope. The
   [18]perspective moves along a valley over a light-year wide, in the
   wall of the region's giant [19]molecular cloud. Orion's valley ends in
   a cavity carved by the energetic [20]winds and [21]radiation of the
   massive central stars of the [22]Trapezium star cluster. The [23]entire
   Orion Nebula spans about 40 [24]light years and is located in the same
   [25]spiral arm of our Galaxy as [26]the Sun.
