In industrial environments, especially in power stations and the oil and gas area, leaks in pipe systems, valves and at critical transfer points have to be identified as quickly as possible. This is e...
Information Technology |Using ESO’s Very Large Telescope and its ability to obtain images as sharp as if taken from space, astronomers have made the first time-lapse movie of a rather unusual shell ejected by a “vampire star...
Physics and Astronomy |The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the ...
Earth Sciences |The project, funded by the U.S. Air Force Multi University Research Initiative (MURI), seeks to test the performance of the new nanocomposites in orbit. Space Shuttle Atlantis will carry the samples t...
Materials Sciences |Since 1990, scientists and mission controllers at ESA and NASA have noticed that their spacecraft sometimes experience a strange variation in the amount of orbital energy they exchange with Earth duri...

Materials Sciences |Rosetta passed over the ocean, just South of the Indonesian island of Java, at exactly 08:45:40 CET, at a speed of 13.34 km/s with respect to Earth at an altitude of 2481 km. The swingby was pre-plann...
Physics and Astronomy |The ELCs will provide scientists with a platform and infrastructure to deploy experiments in the vacuum of space without requiring a separate dedicated Earth-orbiting satellite, and will also serve as...
Physics and Astronomy |Sunspots, which rotate around the sun's surface, tell us a great deal about our own planet. Scientists rely on them, for instance, to measure the sun's rotation or to prepare long-range fore...
Earth Sciences |People love to get the big picture of hurricane alleys, and thanks to the GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md., they can now get real-time satellite animations of ...
Earth Sciences |This afternoon, most of Ida's rains extend to the north and east of her center, over Alabama, Georgia, South and North Carolina. The Geostationary Operational Environmental Satellite, GOE...
Earth Sciences |The system works well, and millions rely on it every day, but what tells the GPS satellites where they are in the first place? "For GPS to work, the orbital position, or ephemeris, of the...
Information Technology |Yet the complexity of nature -- and the models used to quantify it -- continues to serve up surprises. The most recent? Certain gases that cause warming are so closely linked with the production of ae...
Studies and Analyses |Hughes and his Air Force Office of Scientific Research-funded team have conducted high data-rate experiments using an optical laser link, a tool which exploits the quantum noise of light for higher se...
Information Technology |Researchers from Tuskegee University in Alabama conducted a study targeted at finding a way to incorporate natural and fresh antioxidants into the diets of astronauts while traveling in space. They gr...
