A massive cosmic cataloguing effort released a new crop of star and galaxy data last week, noting the locations and brightnesses of hundreds of thousands of objects. Now you can fly through some of them in this new video -- click past the jump for a "flight through the universe."
More than a hundred terabytes dedicated to maps of the universe

In 1998, astronomers using the 2.5-meter Sloan telescope at New Mexico’s Apache Point Observatory began scanning the sky and loading the images they captured into the freely available Sloan Digital Sky Survey database. Since then, astronomers have used that 100-terabyte-plus cache to map half a billion stars, galaxies, asteroids and quasars; create 3-D maps of our outer galaxy; and study the structure of the universe.
After more than a decade of scanning the skies with a 138-megapixel camera mounted on an 8-foot telescope, the Sloan Digital Sky Survey (SDSS) has delivered the largest and most detailed image of the sky ever – an image so detailed and large that it would take half a million high-definition televisions to take it all in at full resolution. And that's just one-third of the sky.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
