This photo, supplied by NASA, shows a portion of Canada's Northwest Passage largely free of ice as seen by NASA's Terra satellite on Sept. 15, 2007. Arctic ice has shrunk to the lowest level on record, new satellite images show, raising the possibility that the Northwest Passage that eluded famous explorers will become an open shipping lane. The European Space Agency said on its web site, Friday, Sept. 15, that nearly 200 satellite photos this month taken together showed an ice-free passage along northern Canada, Alaska and Greenland, and ice retreating to its lowest level since such images were first taken in 1978.
This image provided by NASA Tuesday Oct. 2, 2007 shows a Hubble Space Telescope image of thousands of sparkling young stars nestled within the giant nebula NGC 3603. This stellar "jewel box" is one of the most massive young star clusters in the Milky Way Galaxy. NGC 3603 is a prominent star-forming region in the Carina spiral arm of the Milky Way, about 20,000 light-years away. This latest image from NASA's Hubble Space Telescope shows a young star cluster surrounded by a vast region of dust and gas. The image reveals stages in the life cycle of stars
