Fox News successfully creates climate confusion, but only among conservatives ~ ArsTechnica

fox-global-warming-4eb996d-intro-thumb-640xauto-27507As it turns out, the survey contained information that can help address this issue. Over 40 percent of the self-identified Democrats sometimes watch Fox, while 17 percent of Republicans tune in to CNN and MSNBC. When the numbers for those viewers were broken out, two different trends were apparent. Among Democrats, it didn’t matter how often they watched Fox; their acceptance of climate change remained roughly steady. Republicans who watched MSNBC and CNN, however, had a much higher acceptance than their peers who maintained a strict diet of Fox.

Experience Hubble’s Universe in 3-D

434459main_hs-2010-12-a-full_full 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.

Hubble 3D – Movie Trailer 2010

Review: Hubble 3D Takes You on Beautiful, Brief Space Journey

The premise of Imax: Hubble 3D is simple: Make home movies in space. And what beautiful movies they are. The stunning space vistas and intimate moments with astronauts make for a fascinating flash of interstellar eye candy. The images were captured in 2009 when the space shuttle Atlantis crew left Earth to repair the Hubble Space Telescope. […]

NASA’s WISE Mission Releases Medley of First Images ~ NASA

PASADENA, Calif. — A diverse cast of cosmic characters is showcased in the first survey images NASA released Wednesday from its Wide-field Infrared Survey Explorer, or WISE.

Since WISE began its scan of the entire sky in infrared light on Jan. 14, the space telescope has beamed back more than a quarter of a million raw, infrared images. Four new, processed pictures illustrate a sampling of the mission’s targets — a wispy comet, a bursting star-forming cloud, the grand Andromeda galaxy and a faraway cluster of hundreds of galaxies. The images are online at http://www.nasa.gov/mission_pages/WISE/multimedia/images20100216.html .

"WISE has worked superbly," said Ed Weiler, associate administrator of the Science Mission Directorate at NASA Headquarters in Washington. "These first images are proving the spacecraft’s secondary mission of helping to track asteroids, comets and other stellar objects will be just as critically important as its primary mission of surveying the entire sky in infrared."

WISE Infrared View of Comet Siding Spring One image shows the beauty of a comet called Siding Spring. As the comet parades toward the sun, it sheds dust that glows in infrared light visible to WISE. The comet’s tail, which stretches about 10 million miles, looks like a streak of red paint. A bright star appears below it in blue.

"We’ve got a candy store of images coming down from space," said Edward (Ned) Wright of UCLA, the principal investigator for WISE. "Everyone has their favorite flavors, and we’ve got them all."

During its survey, the mission is expected to find perhaps dozens of comets, including some that ride along in orbits that take them somewhat close to Earth’s path around the sun. WISE will help unravel clues locked inside comets about how our solar system came to be.

Optical Illusions and Visual Phenomena ~ ScienceDaily

Ever get a little motion sick from an illusion graphic designed to look like it’s moving? A 2009 study suggests that these illusions do more than trick the eye; they may also convince the brain that the graphic is actually moving.

Researchers in Japan, led by Akiyoshi Kitaoka of Kyoto’s Ritsumeikan University, monitored brain activity as participants viewed the Rotating Snakes illusion, where concentric circles appear to rotate continuously (see below).

The resulting article, Functional brain imaging of the Rotating Snakes illusion by fMRI, was recently published in the Association of Research in Vision and Ophthalmology’s Journal of Vision as part of a collection of papers on neuroimaging in vision science.

The Pleasure of Finding Things Out: What is Science ~ Richard Feynman

I came across this address while reading, “The Pleasure of Finding Things Out: The Best Short Works of Richard P. Feynman,” and I thought it too good to not pass along. It was given back in 1966 and I found it as relevant today as it was back then.

…a man cannot live beyond the grave. Each generation that discovers something from its experience must pass that on, but it must pass that on with a delicate balance of respect and disrespect, so that the [human] race–now that it is aware of the disease to which it is liable–does not inflict its errors too rigidly on its youth, but it does pass on the accumulated wisdom, plus the wisdom that it may not be wisdom.

It is necessary to teach both to accept and to reject the past with a kind of balance that takes considerable skill. Science alone of all the subjects contains within itself the lesson of the danger of belief in the infallibility of the greatest teachers of the preceding generation.

What is Science?

Richard Feynman

What is science? It is common sense! Or is it? In April 1966 the master teacher delivered an address to the Nation Science Teachers’ Association in which he gave his fellow teachers lessons on how to teach their students to think like a scientist and how to view the world with curiosity, open-mindedness, and, above all, doubt. This talk is also a tribute to the enormous influence Feynman’s father – a uniforms salesman – had on Feynman’s way of looking at the world.

Symphony of Science – ‘We Are All Connected’

Symphony of Science – ‘We Are All Connected’ (ft. Sagan, Feynman, deGrasse Tyson & Bill Nye)

"We Are All Connected" was made from sampling Carl Sagan’s Cosmos, The History Channel’s Universe series, Richard Feynman’s 1983 interviews, Neil deGrasse Tyson’s cosmic sermon, and Bill Nye’s Eyes of Nye Series, plus added visuals from The Elegant Universe (NOVA), Stephen Hawking’s Universe, Cosmos, the Powers of 10, and more. It is a tribute to great minds of science, intended to spread scientific knowledge and philosophy through the medium of music.
