SORCE satellite: A Decade in the Sun

NASA's Solar Radiation and Climate Experiment (SORCE) satellite has been providing data on the sun's irradiance for 10 years. SORCE measures electromagnetic radiation produced by the sun and the power per unit area of that ...

Explaining the mystery of the missing sunspots

Sunspots have been observed for about four centuries, since they were first reported by Galileo. Appearing in roughly eleven-year cycles of activity, sunspots are regions of strong and complex magnetic fields which are also ...

Gold nanoparticles create visible-light catalysis in nanowires

(PhysOrg.com) -- A scientist at the Argonne National Laboratory has created visible-light catalysis, using silver chloride nanowires decorated with gold nanoparticles, that may decompose organic molecules in polluted water.

Clouds and the Alternative Energy Grid

California's goal of generating 33 percent of its power from renewable energy sources by 2020 will be challenging on days when clouds shade acres of solar photovoltaic panels or when thousands of wind turbines spin more slowly ...
