GREENBELT, Md., June 14 /PRNewswire-USNewswire/ -- The Solar X-Ray Imager instrument aboard the GOES-15 satellite has just provided its first light image of the sun, but it required a lot of experts to make it happen. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Scientists and engineers from NASA and the National Oceanic and Atmospheric Administration (NOAA) have been working to bring the Solar X-Ray Imager (SXI) instrument to full functionality since the Geostationary...

A network of cameras deployed around the Arctic in support of NASA's THEMIS mission has made a startling discovery about the Northern Lights. Sometimes, vast curtains of aurora borealis collide, producing spectacular outbursts of light. Movies of the phenomenon were unveiled at the Fall meeting of the American Geophysical Union today in San Francisco. "Our jaws dropped when we saw the movies for the first time," says space scientist Larry Lyons of UCLA, a leading member of the team that made...

A Case Western Reserve University professor says he has developed an imager than can identify and locate individual cancer cells. Biomedical engineering Professor Dave Wilson says he was dissatisfied with blurry, low-sensitivity optical images of diseased tissues, so four years ago he set out to create a better imager. He says his new device can identify a single cancer cell in preclinical imaging studies and it can pinpoint exactly where the cell is located in a three-dimensional image....

Dave Wilson was dissatisfied with blurry, low-sensitivity optical images of diseased tissues. So, four years ago he set out to create a better imager. Now, Wilson, a professor of biomedical engineering at Case Western Reserve University, can identify a single cancer cell in preclinical imaging studies. And he can pinpoint exactly where the cell is located in a three-dimensional image. Called cryo-imaging, the system enables Wilson and collaborators to identify single molecules, count the...

LOS ANGELES (AP) - A NASA satellite studying the Earth's magnetic field has stopped operating after six years, the space agency said Friday. The Image satellite, launched in 2000, successfully completed its two-year primary mission, according to a NASA news release. It made observations until last month when engineers discovered that its power supply had failed. Image - short for Imager for Magnetosphere-to-Aural Global Exploration - was the first space probe to study the entire...
