Cosmochemists Help Solve 135-Year-Old Meteorite Mystery
2013-07-08 15:09:49

Lee Rannals for redOrbit.com - Your Universe Online Scientists have provided a solution to a 135-year-old mystery in cosmochemistry, saying chondrules may have formed from high-pressure collisions in the early Solar System. Chondrites are the largest class of meteorites, and scientists have wondered how numerous small, glassy spherules had become embedded within them. British mineralogist Henry Sorby first described these spherules in 1877 and suggested they may be "droplets of fiery...

Scientists are tracking the violent convulsions in the giant cloud of gas and dust that gave birth to the solar system 4.5 billion years ago via a few tiny particles from comet Wild 2. These convulsions flung primordial material billions of miles from the hot, inner regions of the gas cloud that later collapsed to form the sun, out into the cold, nether regions of the solar system, where they became incorporated into an icy comet. "If you take a gas of solar composition and let it cool down,...

Chicago -- Scientists at the American Museum of Natural History and the University of Chicago have explained how a globe-encircling residue formed in the aftermath of the asteroid impact that triggered the extinction of the dinosaurs. The study, which will be published in the April issue of the journal Geology, draws the most detailed picture yet of the complicated chemistry of the fireball produced in the impact. The residue consists of sand-sized droplets of hot liquid that condensed from...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
