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.

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.

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.

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.

"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.

"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."

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.

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. The Carina Nebula is a nursery for baby stars.

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 vi

Edited European Southern Observatory image of the galaxy M98. Color/processing variant.

Original caption: The colour blue has many associations — coldness, sadness, serenity. However, the colour holds a completely different meaning for astronomers, as demonstrated by the edge-on spiral galaxy Messier 98. Messier 98, also known as NGC 4192, is located approximately 50 million light-years away in the constellation of Coma Berenices (Berenice’s Hair). In this spectacular image from ESO’s New Technology Telescope (NTT), the galaxy’s perimeter, rippled with gas and dust, is dotted with pockets of blueish light. These are regions filled with very young stars, which are so hot that they glow with a bright blue hue. These young stars are burning at such high temperatures that they are emitting fierce radiation, burning away some of the dense material that surrounds them. In total, Messier 98 is thought to contain one trillion stars! The NTT is a 3.58-metre telescope at the La Silla Observatory, which pioneered the use of active optics and was the first in the world to have a computer-controlled main mirror.

Tämä onkin kuvattu melkein 10 kuukautta takaperin, Ursan Syvä taivas -harrastusryhmän deep sky -miitin kahtena yönä. Linnunrataosio on kuvattu panoraamaksi seurannalla (30s valotus, polttoväli 135mm) ja maisemaosio samalla objektiivilla — tietysti ilman seurantaa (10min). Postasin tämän vasta nyt, koska kuvankäsittely on ollut gradienttien eliminoinnin suhteen ihan painajaismaista. Tulos ei nytkään ole varsinaisesti hyvä, mutta olkoot.

Ensin koitin gradienttien siivousta IRIS-ohjelmalla, jälki oli ihan kauheaa, teki sen polynomimallilla tai lokaalisti. Photoshopilla sai paremman tuloksen, mutta kaikki piti tehdä käsin. Gradientit saa kuvasta häipymään ihan ajamalla dust and scratches -suodin kuvalle todella suurella, 500 pikselin säteellä. Sen voi onneksi tehdä eräajona, koska yhden kuvan siivoamiseen menee minuutti CPU-aikaa ihan nykyaikaisella koneellakin. Alkuperäisestä kuvasta voi sitten vähentää tähdettömän kuvan apply imagella, taustataivas katoaa siinä samalla ja näistä kuvista voi kasata lopulta panoraaman. Tämän haittapuolena on se että taustataivaan väri katoaa kuvasta samalla. Maisemattomassa kuvassa se ei haittaisi, koska kiintopistettä horisontissa kuvan taustaitaivaan väreille ei ole, mutta maisemaan taivasta sulauttaessa joutuu kikkailemaan totuttua enemmän jotta lopputuloksesta saa edes joltiseltaan tolkullisen. Muuten värit olen pyrkinyt pitämään sellaisina kun ne yöllä ovat, lähinnä keltaisina.
