The new atomic age: building smaller, greener electronics
Edmonton, Canada (SPX) Jul 09, 2014 -
In the drive to get small, Robert Wolkow and his lab at the University of Alberta are taking giant steps forward. The digital age has resulted in a succession of smaller, cleaner and less power-hungry technologies since the days the personal computer fit atop a desk, replacing mainframe models that once filled entire rooms.
Desktop PCs have since given way to smaller and smaller laptops, s ...

GPM Satellite Sees First Atlantic Hurricane
Greenbelt MD (SPX) Jul 11, 2014 -
The Global Precipitation Measurement (GPM) Core Observatory flew over Hurricane Arthur five times between July 1 and July 5, 2014. Arthur is the first tropical cyclone of the 2014 Atlantic hurricane season. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency. The Core Observatory was launched Feb. 27 from Japan and began its prime mission on May 29, just in time for th ...

Cosmic accounting reveals missing light crisis
Pasadena CA (SPX) Jul 11, 2014 -
Something is amiss in the Universe. There appears to be an enormous deficit of ultraviolet light in the cosmic budget. The vast reaches of empty space between galaxies are bridged by tendrils of hydrogen and helium, which can be used as a precise "light meter."
In a recent study published in The Astrophysical Journal Letters, a team of scientists finds that the light from known populations ...

Supermassive black hole blows molecular gas out of galaxy
Sheffield, UK (SPX) Jul 11, 2014 -
New research by academics at the University of Sheffield has solved a long-standing mystery surrounding the evolution of galaxies, deepening our understanding of the future of the Milky Way.
The supermassive black holes in the cores of some galaxies drive massive outflows of molecular hydrogen gas. As a result, most of the cold gas is expelled from the galaxies. Since cold gas is required ...

Cosmic grains of dust formed in supernova explosion
Copenhagen, Denmark (SPX) Jul 11, 2014 -
There are billions of stars and planets in the universe. A star is glowing sphere of gas, while planets like Earth are made up of solids. The planets are formed in dust clouds that swirled around a newly formed star.
Dust grains are composed of elements like carbon, silicon, oxygen, iron, and magnesium. But where does the cosmic dust come from? New research from the Niels Bohr Institute at ...

New Technology Illuminates Colder Objects in Deep Space
Evanston IL (SPX) Jul 11, 2014 -
Too cool and faint, many objects in the universe are impossible to detect with visible light. Now a McCormick team has refined a new technology that could make these colder objects more visible, paving the way for enhanced exploration of deep space.
"High performance infrared cameras are crucial for space exploration missions," said Manijeh Razeghi, the Walter P. Murphy Professor of Electr ...
