They came, they saw, they took pictures. And thanks to them -- about 150,000 Flickr users -- a team of computer scientists built Rome in a day.
Using nearly half a million Flickr photos of Rome, Venice, and the Croatian coastal city of Dubrovnik, a team of computer scientists at the University of Washington's Graphics and Imaging Laboratory assembled digital models of the three cities in 3-D.
The newly-refurbished Hubble Space Telescope sent back its first breathtaking images after being repaired in September. Here, Nebula NGC 6302 with its butterfly wings of 36,000-degree gas.
We always like to look forward to bigger and better tech, but NASA's Hubble Space Telescope, though it's been around the block, still holds a special place in every geek's heart. Now the freshly repaired and upgraded telescope has resumed churning out enough images of cosmic glory to turn anyone's head.
This photo of Mount Redoubt, caught in mid-eruption, was taken from a height of 423 miles, on March 30, 2009 as the GeoEye-1 satellite moved from north to south over Alaska at a speed of 4 miles per second. Since the amount of area is so large, the ground resolution of this image is 2 meters.
Try this: See that bright blue sign on the far wall? Can you read it? Double-click it. Can you read it now? Now move in again. And again.
This impressive panorama is actually a collection of 592 distinct photos, shot with a Canon Powershot with a 360mm zoom, and the help of a nifty gadget called the GigaPan Epic. Plop your camera into the device and it will automatically take between 20 and several hundred slightly overlapping pictures of a scene. The GigaPan software stitches them together for you into one massive, ultra-detailed, thousands-of-megapixels collage.
As promised, here are stunningly clear satellite images of the tops of some two million heads during today’s inauguration. These images were snapped at 11:19am today by GeoEye-1, the most powerful commercial imaging satellite in the sky, from 423 miles above the trampled grass on the National Mall.

The 951 (and counting) birds collected alive after the San Francisco Bay oil spill are doing their part for science. Some of the birds are now subjects in studies led by veterinarians at the UC Davis Oiled Wildlife Care Network, who hope to improve treatments for oiled birds everywhere.
One study is using infrared thermography to spot birds that are losing heat too quickly [image at left]. In another study, birds will be equipped with radio transmitters so that researchers can study where they go and how long they live after they are released from the care center.
Of those 951 birds found alive, 197 later died or were euthanized, and 394 were washed. The remaining 360 are being monitored and fed in a warm room until they are strong enough for a bath.—Dawn Stover

For a gallery of Hubble's most incredible images, click "View Photos" at left The terrific thing about NASA chief Michael Griffin's decision to launch a Hubble servicing missionthe telescope's fifth since 1990isn't simply that the spacecraft will be able to limp along for another four years. After astronauts visit Hubble on this latest mission (set to launch no earlier than May 2008), the telescope will be more powerful than it has ever been, thanks to some incredible new instruments being tested now.
