Our Known Universe

Dan Coleman,  at the Open Culture blog, features a new video by the American Museum of Natural History on YouTube.

"The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History.
"The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010. "
If you're interested in knowing more about the Universe, String Theory, and AstroPhysics in general, watch The Elegant Universe videos. The Elegant Universe was a 3 hour mini-series from NOVA, on US Public Television. At its home web page you'll find articles and interviews, slide shows, interactive activities, and downloadable resources about "eleven dimensions, parallel universes, and a world made out of strings - it's not science fiction, it's string theory."
"One of the most ambitious and exciting theories ever proposed—one that may be the long-sought "theory of everything," which eluded even Einstein—gets a masterful, lavishly computer-animated explanation from bestselling author-physicist Brian Greene, when NOVA presents the nuts, bolts, and sometimes outright nuttiness of string theory."
