Explanation: What would it look like to fly into the Orion Nebula? The exciting dynamic visualization of the Orion Nebula is based on real astronomical data and adept movie rendering techniques. Up close and personal with a famous stellar nursery normally seen from 1,500 light-years away, the digitally modeled representation based is based on infrared data from the Spitzer Space Telescope. The perspective moves 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 entire Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.

说明: 飞入猎户大星云会看到什么？这部猎户大星云的动态视像化影片，让我们得以如身临实境般的穿行在这个通常远在1,500光年之外的恒星形成区里，而这部数位模型电影，则是建构自真实的天文物理数据（史匹哲太空望远镜的红外光数据）和熟练的电影呈像技术。在影片里，视线沿此区巨分子云的云墙内，一道宽约1光年多的凹谷前行。这个凹谷之旅，终结于由四边形星团中心的大质量恒星之强烈恒星风和辐射，所清出的空穴。猎户大星云宽约40光年，与太阳位在同一条银河系旋臂上。
