Experience Hubble's Universe in 3-D

This image depicts a vast canyon of dust and gas in the Orion Nebula
from a 3-D computer model based on observations by NASA's Hubble Space
Telescope and created by science visualization specialists at the Space
Telescope Science Institute (STScI) in Baltimore, Md. A 3-D
visualization of this model takes viewers on an amazing four-minute
voyage through the 15-light-year-wide canyon. The model takes viewers
through an exhilarating ride through the Orion Nebula, a vast
star-making factory 1,500 light-years away. This virtual space journey
isn't the latest video game but one of several groundbreaking astronomy
visualizations created by specialists at STScI, 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. 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. 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. 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. 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. 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. Image Credit: NASA, G. Bacon, L. Frattare, Z. Levay,
