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 |During the summer of 1997-1998, measurements of beam absorption and beam attenuation coefficients, and downwelling and upwelling irradiance were made in the Southern Ocean along a S-N transect at 6 de...
Earth Sciences |Analysts at NanoMarkets forecast a worldwide market volume of over $2.9 billion for 2012, with sales increasing to around $5.9 billion by 2014. The lighting industry is now looking for economic produc...
Power and Electrical Engineering |Reported by Megawati Omar, Research Management Institute, UiTMResearchers Mohd Zainizan Sahdan, Mohd Hafiz Mamat, Zuraida Khusaimi, Mohd Noor and Mohd Rusop Mahmud of the Faculty of Electrical...
Physics and Astronomy |In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an intensive, high-...
Life 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 SUNRISE balloon-borne telescope, a collaborative project between the Max Planck Institute for Solar System Research in Katlenburg-Lindau and partners in Germany, Spain and the USA, has now deliver...
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 |Fangzhen Teng, assistant professor of geosciences at the University of Arkansas, and Wei Yang and Hong-Fu Zhang of the Chinese Academy of Sciences report their findings in Earth and Planetary Science ...
Physics and Astronomy |"Intermediate-mass black holes contain between 100 and 10,000 times the sun's mass," explained Tod Strohmayer, an astrophysicist at Goddard. "We observe the heavyweight black holes...
Physics and Astronomy |That's the topic of a report by an international expert on solar energy scheduled for the November 2 issue of ACS’ Inorganic Chemistry, a bi-weekly journal. It describes a long-awaited, inexpensi...
Power and Electrical Engineering |This will be the third Earth swingby, the last of Rosetta’s four planetary gravity assists. Closest approach to Earth is expected at 08:45 CET (07:45 UT). The swingby will provide exactly the boost Ro...
Physics and Astronomy |Using zinc oxide nanostructures grown on optical fibers and coated with dye-sensitized solar cell materials, researchers at the Georgia Institute of Technology have developed a new type of three-dimen...
Power and Electrical Engineering |Converting sunlight to electricity might no longer mean large panels of photovoltaic cells atop flat surfaces like roofs. Using zinc oxide nanostructures grown on optical fibers and coated wit...
Power and Electrical Engineering |The sun is the energy source not only done for photovoltaic cells but also for thermal solar collectors. Whereas photovoltaic cells transform the sun's energy directly into electricity, solar col...
