Coronol Holes Found In The Sun By Nasa

The dark area across the top of the sun in this image is a coronal hole, a region on the sun where the magnetic field is open to interplanetary space, sending coronal material speeding out in what is called a high-speed solar wind stream. The high-speed solar wind originating from this coronal hole, imaged here on Oct. 10, 2015, by NASA's Solar Dynamics Observatory, created a geomagnetic storm near Earth that resulted in several nights of auroras. This image was taken in wavelengths of 193 Angstroms, which is invisible to our eyes and is typically colorized in bronze.

Fluor-liddicoatite [or just Liddocoatite] is Rare.

Fluor-liddicoatite [or just Liddocoatite] is a rare member of the tourmaline group of minerals, elbaite subgroup, and the theoretical calcium end-member of the elbaite-fluor-liddicoatite series.

Making Green Fuels, No Fossils Required

Nitrogen-doped carbon nanotubes proved to be efficient, and potentially inexpensive, catalysts for reducing carbon dioxide. Credit: Adapted from Angewandte Chemie Using solar or wind power to produce carbon-based fuels, which are commonly called fossil fuels, might seem like a self-defeating approach to making a greener world. But when the starting material is carbon dioxide, which can be dragged out of the air, the approach is as green as it gets. The technology that makes it economically feasible isn't available yet, but a recently published paper presents nice step forward in the effort to not just sequester CO2, but turn it into a useful fuel that is part of a carbon-neutral future. Xiao-Dong Zhou, an associate professor of chemical engineering at the University of South Carolina, is part of a team that is working on a sustainable approach to harnessing renewable energy. Solar panels and wind turbines are most typically used to produce electricity, bu
