  NASA Finds Mysterious Glow in Deep Space                             Source:  NASA New Horizon Spacecraft New Science: Discovery of Light in Space From Outside Our Galaxy This is remarkable astronomy just reported by scientists at NASA.  For decades, scientists have been unable to answer the question:  How dark is space?  Meaning, is there any light in the inky darkness that you see in the night sky between stars and galaxies?  Through painstaking analysis, NASA scientists have discovered there is the mysterious glow of light in deep space coming from outside of our galaxy.   New Horizon Mission The NASA mission, to determine how dark space really is, is called New Horizon.  The New Horizon spacecraft is 4 billion miles from Earth and has provided astronomers with a series of images from its telescopes.  NASA scientists processed out any light from stars and galaxies.  They then found the glow of light - and plenty of it - coming in from outside our galaxy.  Their discovery is a firs

New, Transformative Device to Generate Power from Night Sky Source:   UCLA Renewable and Complements Solar Power This new, inexpensive thermoelectric device may be transformative in energy generation.  It harvests the coldness of space during the night to generate electricity - enough right now to power a LED light at nighttime, but the inventors say it's very scalable.  The device is a significant new innovation from engineers at UCLA and Stanford University.  The gadget works at night when solar systems don't.  The inventors say it's a new approach to power generation when power at night is needed.  It complements solar power that doesn't work at night, giving a 24/7 approach to green, renewable energy. Phenomenon Like Frost Formation The device takes advantage of radiative cooling, the process by which frost forms on grass during above freezing temperatures at night.  The sky facing surface of the technology passes heat to the atmosphere as thermal radiat
