This video was made from CT scans of a slice (45 mm x 55 mm x 4 mm) of the NWA 7034 (AKA “Black Beauty”) Martian meteorite from the ASU Center for Meteorite Studies collection. This meteorite is a polymict breccia containing a diverse assemblage of igneous and “sedimentary” materials. It was most likely produced […]

World’s most abundant mineral finally named, thanks to meteorite research!
While researchers have long known that our planet’s most abundant solid phase is magnesium iron silicate (Mg,Fe)SiO3, since this material occurs deep below Earth’s surface, in the lower mantle, it has remained officially nameless until now (in order to receive a formal, recognized name, a mineral sample must be available for characterization). In a new […]
Arizona State University joins Murchison Widefield Array radio telescope project
In becoming a partner in the Murchison Widefield Array radio telescope, scientists from ASU’s School of Earth and Space Exploration will be using it to explore the beginning of the universe. Arizona State University has joined with 14 other institutions in Australia, India, New Zealand, and the United States in a radio telescope project that […]
Asteroid impacts on Earth make structurally bizarre diamonds
Scientists have argued for half a century about the existence of a form of diamond called lonsdaleite, which is associated with impacts by meteorites and asteroids. A group of scientists based mostly at Arizona State University now show that what has been called lonsdaleite is in fact a structurally disordered form of ordinary diamond. The […]
Geologic mapping of asteroid Vesta reveals history of large impacts
A team of 14 scientists led by David Williams of Arizona State University's School of Earth and Space Exploration has completed the first global geologic and tectonic map of the asteroid Vesta. The work reveals that Vesta's history has been dominated by impacts from large meteorites. The mapping was carried out using images from NASA's […]
