Powering lasers through heat

In micro electronics heat often causes problems and engineers have to put a lot of technical effort into cooling, for example micro chips, to dissipate heat that is generated during operation. Austrian physicists have now ...

Cassini Halloween treat: Titan glows in the dark

(Phys.org)—A literal shot in the dark by imaging cameras on NASA's Cassini spacecraft has yielded an image of a visible glow from Titan, emanating not just from the top of Titan's atmosphere, but also - surprisingly - from ...

NASA spacecraft records 'Earthsong'

Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.

Mystery of dark matter may be near to being deciphered

(Phys.org)—The universe is comprised of a large amount of invisible matter, dark matter. It fills the space between the galaxies and between the stars in the galaxies. Since the prediction of the existence of dark matter ...

New system could predict solar flares, give advance warning

(Phys.org) -- Researchers may have discovered a new method to predict solar flares more than a day before they occur, providing advance warning to help protect satellites, power grids and astronauts from potentially dangerous ...

Tiny airborne pollutants lead double life: study

University of British Columbia and Harvard researchers have provided visual evidence that atmospheric particles -- which are ubiquitous in the atmosphere, especially above densely populated areas -- separate into distinct ...

XENON100 sets record limits for dark matter

Scientists from the XENON collaboration announced a new result from their search for dark matter. The analysis of data taken with the XENON100 detector during 13 months of operation at the Gran Sasso Laboratory (Italy) provided ...

The electric atmosphere: Plasma is next NASA science target

Our day-to-day lives exist in what physicists would call an electrically neutral environment. Desks, books, chairs and bodies don't generally carry electricity and they don't stick to magnets. But life on Earth is substantially ...
