99942 Apophis ( /əˈpɒfɪs/, previously known by its provisional designation 2004 MN4) is a near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a small probability (up to 2.7%) that it would strike the Earth in 2029. http://en.wikipedia.org/wiki... , 12 -27 http://en.wikipedia.org/wiki... http://en.wikipedia.org/wiki... http://en.wikipedia.org/wiki... http://www.treehugger.com/natural... , 2 -12 -13 http://en.wikipedia.org/wiki... http://www.spacedaily.com/reports... - Thomas Page

"The south polar mountain on Vesta is very, very large—almost as large as the largest mountain in the solar system, Olympus Mons," Russell said, referring to the towering, roughly 25-kilometer volcanic peak on Mars. "We have not figured out the tectonic cause of the south polar mountain, so that's work ahead of us." http://www.scientificamerican.com/article... - Thomas Page

sort 12 -4 Perovskite_solar_cell http://en.wikipedia.org/wiki... Perovskite absorber materials such as methylammonium or formamidinium lead halide are extremely cheap to produce and simple to manufacture. Solar cell efficiencies of devices using these materials have increased from 3.8% in 2009 [1] to a certified 20.1% in 2014, making this the fastest-advancing solar technology to date. Their high efficiencies and cheap production costs make perovskite solar cells an extremely commercially attractive option, with start-up companies already promising modules on the market by 2017 http://en.wikipedia.org/wiki... http://en.wikipedia.org/wiki... http://en.wikipedia.org/wiki... Silicate perovskite is thought to be the main constituent of the lower mantle,[4] possibly reaching up to 93% by volume.[3] Magnesium silicate perovskite is probably the most abundant mineral phase in the Earth.[4] The highest proposed abundances of silicate perovskites suggest that the lower mantle is richer in silica than the upper mantle and are consistent with the overall chondritic composition of the Earth. http://en.wikipedia.org/wiki... - Thomas Page
