新闻全文：
Take an exhilarating ride through the Orion Nebula, a vast star-making factory 1,500 light-years away. Swoop through Orion's giant canyon of gas and dust. Fly past behemoth stars whose brilliant light illuminates and energizes the entire cloudy region. Zoom by dusty tadpole-shaped objects that are fledgling solar systems.
想象一下穿越猎户座大星云的虚拟旅行，它是离我们1500光年外广袤的恒星孕育场。在气体尘埃组成的峡谷中俯冲；在照亮了整个星云的灿烂巨星上方翱翔，去观赏正在形成中的蝌蚪状原始太阳星云。
This virtual space journey isn't the latest video game but one of several groundbreaking astronomy visualizations created by specialists at the Space Telescope Science Institute (STScI) in Baltimore, the science operations center for NASA's Hubble Space Telescope. The cinematic space odysseys are part of the new Imax film "Hubble 3D," which opens today at select Imax theaters worldwide.
这些虚拟的空间之旅并非最新发布的3D游戏，而是由数位太空望远镜科研所（STScI）的专家创建的革命性可视化天文学系列之一。STScI位于巴尔的摩市，是哈勃太空望远镜的科学操作中心。这段太空漫游电影是新的IMAX电影“哈勃3D”的一部分，新电影今天在全球多个IMAX影院上映。
The 43-minute movie chronicles the 20-year life of Hubble and includes highlights from the May 2009 servicing mission to the Earth-orbiting observatory, with footage taken by the astronauts.
这部43分钟的电影回顾了哈勃20年来的成就，其中的重头戏是2009.5对哈勃的第5次太空维护任务，其中有大量宇航员自己拍摄的长镜头。
The giant-screen film showcases some of Hubble's breathtaking iconic pictures, such as the Eagle Nebula's "Pillars of Creation," as well as stunning views taken by the newly installed Wide Field Camera 3.
巨幕电影还展示了多个哈勃拍摄的震撼性标志图像，其中有著名的鹰状星云中的“创生之柱”，以及新安装的第三代广域相机（WFC3）拍摄的极为清晰的大图。
While Hubble pictures of celestial objects are awe-inspiring, they are flat 2-D photographs. For this film, those 2-D images have been converted into 3-D environments, giving the audience the impression they are space travelers taking a tour of Hubble's most popular targets.
虽然哈勃拍摄大量的震撼性图像，但它们都是平面图像。而在电影中，它们被转换为3D视频，给观众以身临其境的感觉：他们正在浏览、穿越这些广为人知的天体。
"A large-format movie is a truly immersive experience," says Frank Summers, an STScI astronomer and science visualization specialist who led the team that developed the movie visualizations. The team labored for nine months, working on four visualization sequences that comprise about 12 minutes of the movie.
这部电影的可视化天文效果专家团队领导、太空望远镜科研所（STScI）的天文学家弗兰克.萨默斯（夏天？）说：“一场大型电影是最好的亲身体验。”团队辛苦工作了9个月，完成了总长12分钟的4个可视化序列。
"Seeing these Hubble images in 3-D, you feel like you are flying through space and not just looking at picture postcards," Summers continued. "The spacescapes are all based on Hubble images and data, though some artistic license is necessary to produce the full depth of field needed for 3-D."
萨默斯继续说：“浏览这些哈勃图像的3D效果，你会觉得是在太空中漫游，而不仅仅是观看漂亮的明信片。所有这些太空世界都是基于哈勃图像数据制作的，当然为了达到足够的景深效果，我们做了必要的艺术化处理。”
The most ambitious sequence is a four-minute voyage through the Orion Nebula's gas-and-dust canyon, about 15 light-years across. During the ride, viewers will see bright and dark, gaseous clouds; thousands of stars, including a grouping of bright, hefty stars called the Trapezium; and embryonic planetary systems. The tour ends with a detailed look at a young circumstellar disk, which is much like the structure from which our solar system formed 4.5 billion years ago.
这其中，最壮观的是4分钟产的猎户座大星云之旅：穿过15光年长的气体、尘埃峡谷。旅程中，观众将看到明暗闪烁的气体云、原始的行星系统、数千群星，其中就包括特别明亮的四合星。旅程终点是一个极为年轻的行星盘系统，很像45亿年前的太阳系。
Based on a Hubble image of Orion released in 2006, the visualization was a collaborative effort between science visualization specialists at STScI, including Greg Bacon, who sculpted the Orion Nebula digital model, with input from STScI astronomer Massimo Roberto; the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign; and the Spitzer Science Center at the California Institute of Technology in Pasadena.
猎户座大星云的3D视频基于2006年拍摄的哈勃图像，太空望远镜科研所的可视化效果专家包括：3D建模：Greg Bacon； 数字输入：Massimo Roberto。合作单位还有：位于伊里诺州大学香槟分校的美国国家超级计算应用中心（NCSA）、帕萨迪纳市加州理工学院的斯皮策科学中心等。
For some of the sequences, STScI imaging specialists developed new techniques for transforming the 2-D Hubble images into 3-D. STScI image processing specialists Lisa Frattare and Zolt Levay, for example, created methods of splitting a giant gaseous pillar in the Carina Nebula into multiple layers to produce a 3-D effect, giving the structure depth. The Carina Nebula is a nursery for baby stars.
在某些视频序列中，太空望远镜科研所（STScI）专家开发了新技术，把平面的哈勃图像立体化。例如，STScI的图像处理专家 Lisa Frattare、 Zolt Levay 把猎户座大星云（M42）的气体云柱拆分为多个层，以创建立体景深效果。M42是个著名的恒星孕育场所。
Frattare painstakingly removed the thousands of stars in the image so that Levay could separate the gaseous layers on the isolated Carina pillar. Frattare then replaced the stars into both foreground and background layers to complete the 3-D model. For added effect, the same separation was done for both visible and infrared Hubble images, allowing the film to cross-fade between wavelength views in 3-D.
Frattare煞费苦心地移除了M42视场中数千群星，如此Levay就能分拆、创建云柱的各层了。然后Frattare再把群星移回，组成前景、背景星的各个层，完成3D建模。要添加更多的效果，就要对哈勃拍摄的可见光和红外光图像都进行相同的分离—组合操作，以实现电影中的渐入渐出效果。
In another sequence viewers fly into a field of 170,000 stars in the giant star cluster Omega Centauri. STScI astronomer Jay Anderson used his stellar database to create a synthetic star field in 3-D that matches recent razor-sharp Hubble photos.
在另一个视频序列中，观众将深入巨大的球状星团——半人马座ω，场景中有17万颗以上恒星。STScI天文学家Jay Anderson 根据恒星数据库创建的3D恒星视场效果，堪比哈勃的照片清晰度。
The film's final four-minute sequence takes viewers on a voyage from our Milky Way Galaxy past many of Hubble's best galaxy shots and deep into space. Some 15,000 galaxies from Hubble's deepest surveys stretch billions of light-years across the universe in a 3-D sequence created by STScI astronomers and visualizers. The view dissolves into a cobweb that traces the universe's large-scale structure, the backbone from which galaxies were born.
电影中最后的4分钟视频中，STScI的专家和视觉艺术家为我们展示了宇宙最深处之旅：我们的视野从银河系出发，快速飞过哈勃拍摄的那些最佳星系，深入数十亿光年外的宇宙最深处——天炉座哈勃超级深空场。我们的视线最后逐步溶入宇宙的大尺度结构——宇宙的网状结构，它们是星系诞生的骨架支柱。
In addition to creating visualizations, STScI's education group also provided guidance on the "Hubble 3D" Educator Guide, which includes standards-based lesson plans and activities about Hubble and its mission. Students will use the guide before or after seeing the movie.
除了创建可视化效果，STScI的公众教育部门还提供了“哈勃3D”的指导手册，其中包括关于哈勃及其任务的基础知识、相关活动等。学生们可在电影前、后查询这些手册。
"The guide will enhance the movie experience for students and extend the movie into classrooms," says Bonnie Eisenhamer, STScI's Hubble Formal Education manager.
STScI的教育项目部经理Bonnie Eisenhamer说：“这些手册将提升电影的体验效果，并把电影效应延伸到课堂中。”
