Located 35 miles east of Flagstaff and 6 miles south of Interstate 40, Meteor Crater and its fragments were first recognized after the discovery of iron fragments west of the crater near Canyon Diablo ...
Our Solar System contains tens of thousands of potentially dangerous asteroids that could wipe out an entire city, or worse. In Washington, a NASA office is leading efforts to spot and neutralize ...
India’s landscape quietly reveals evidence of cosmic collisions, where asteroids struck the Earth and left craters that sometimes became lakes. These rare remnants of cosmic events are fascinating ...
Eugene Shoemaker, the founder of astrogeology, dedicated his life to understanding planetary formation through impacts. His groundbreaking research proved asteroid impacts shaped Earth and other ...

MAGEMin is a Gibbs energy minimization solver package, which computes the thermodynamically most stable assemblage for a given bulk rock composition and pressure/temperature condition. It also returns ...
ABSTRACT: P-T trajectories based on depth-controlled metamorphism have been questioned by some scholars, as they only consider static rock pressure and ignore fluid pressure, tectonic stress, and ...
Silica phases, SiO2, have attracted significant attention as important phases in the fields of condensed-matter physics, materials science, and (in view of their abundance in the Earth's crust) ...
Very marked differences in the metastable persistence of coesite and stishovite have been demonstrated; the former possibly persists indefinitely below 1000 degrees C at 1 atmosphere "dry," and the ...
Founded in 1921, Society for Science & the Public's mission is to advance public understanding and appreciation of scienceamong people of all ages through publications and educational programs. A ...
Deep below the surface of our world, far beyond our feeble reach, enigmatic processes grind and roil. Every now and then, the Earth disgorges clues to their nature: tiny chthonic diamonds encasing ...
The moon is a barren and desolate place, with no signs of life or civilization. But there is one human being who rests there in eternal peace: Dr. Eugene Shoemaker, a pioneer of planetary science and ...
