Researchers led by the University of Arizona found a grain of dust in Antarctica that may be able to teach us about the creation of our solar system. In a paper set to be published on April 29th, ...

Gravity is incredibly weak. Just think: You can lift your foot despite the mass of the entire Earth pulling against it. Why is it so weak? That’s unclear. And it might take a very, very big science ...

Concentrated solar power (CSP) systems employing solid particle receivers represent a promising advancement in renewable energy technology. By replacing conventional heat transfer fluids with solid ...

A large team of researchers working on the Alpha Magnetic Spectrometer Collaboration, which has been analyzing eleven years' ...

NASA has selected two instruments led by Southwest Research Institute to measure energetic particles for the Solar Probe Plus spacecraft, slated to launch by 2018. This first-ever journey into the Sun ...

Solar flares are among the most violent explosions in our solar system, but despite their immense energy — equivalent to a hundred billion atomic bombs detonating at once — physicists still haven’t ...
