sun

Arizona gets plenty of sunlight, and researchers there are working hard to turn that energy into electricity we can use. At Arizona State University, graduate student Brad Brennan makes and tests new materials that will allow us to build smaller, cheaper, flexible photovoltaic solar cells that can go almost anywhere. Brittany Lynn, a student at the University of Arizona, has been testing solar cells with different surfaces to see how surface shape affects the energy production of the cells.

Giver of light, supporter of life, energy, climate and season device. The sun is a star, we're glad it is here, as our life support, for 5 billion years. This star is among the brightest in space, though close, many questions about it remain. With violet ,orange, and reddish of hues, our home solar system...

Resonance is the quality of transmitting even tiny signals between systems that are tuned to the same frequency. Given that cycles of common period are found pervading many different disciplines, perhaps an explanation may be found in resonance. An example is the 160 minute (and associated 80 minute cycle) cycle, found in biological systems, outer planetary spacings, the rotation rates of planets, asteroids and binary stars, solar oscillation and flux and galactic cores. A cosmic pervading...
