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...

redOrbit Staff & Wire Reports - Your Universe Online The formative stages of the Milky Way, once believed to have taken far longer to occur than other solar systems, may not have been as unique as scientists had previously thought, according to the authors of a new study. Writing in the journal Science, researchers from the Centre for Star and Planet Formation at the Natural History Museum of Denmark, University of Copenhagen report they have discovered a pair of vastly different...

The earliest rocks in our solar system were more like candy floss than the hard rock that we know today, according to research published today in the journal Nature Geoscience The earliest rocks in our Solar System were more like candy floss than the hard rock that we know today, according to research published today in the journal Nature Geoscience. The work, by researchers from Imperial College London and other international institutions, provides the first geological evidence to support...

Nanoprobe reveals life history of meteorite from early solar system Scientists have performed a micro-probe analysis of the core and outer layers of a pea-sized piece of a meteorite some 4.57 billion years old to reconstruct the history of its formation, providing the first evidence that dust particles like this one experienced wildly varying environments during the planet-forming years of our solar system. The researchers interpret these findings as evidence that dust grains traveled over...

Meteorites provide valuable information about the early history of the solar system. A group of Swiss geologists have conducted systematic meteorite searches in Oman since 2001, and they recently returned from their latest hunt.Most meteorites are fragments of asteroids, some of which contain organic matter. Some meteorites preserve information on the chemical make-up of the solar system before the planets formed. Other meteorites are impact debris from the surfaces of the Moon and Mars....

Higher than expected levels of sodium found in a 4.6 billion-year-old meteorite suggest that the dust clouds from which the building blocks of the Earth and neighboring planets formed were much denser than previously supposed. The study, by scientists from the Carnegie Institution, American Museum of Natural History, and U.S. Geological Survey, is published in the June 20 issue of Science. Conel Alexander and Fred Ciesla of the Carnegie Institution's Department of Terrestrial Magnetism, with...

A U of T scientist has found unexpectedly "Ëœyoung' material in meteorites "“ a discovery that breaks open current theory on the earliest events of the solar system. A paper published today in the August issue of Nature reports that the youngest known chondrules "“ the small grains of mineral that make up certain meteorites "“ have been identified in the meteorites known as Gujba and Hammadah al Hamra. Researchers who have studied chondrules generally agree that...

LIVERMORE, Calif. -- The oxygen and magnesium content of some of the oldest objects in the universe are giving clues to the lifetime of the solar nebula, the mass of dust and gas that eventually led to the formation of our solar system. By looking at the content of chondrules and Calcium Aluminum- rich inclusions (CAIs), both components of the primitive meteorite Allende, Lab physicist Ian Hutcheon, with colleagues from the University of Hawaii at Manoa, the Tokyo Institute of Technology and...

Carnegie -- Scientists now believe that the formation of Jupiter, the heavy-weight champion of the Solar System's planets, may have spawned some of the tiniest and oldest constituents of our Solar System -- millimeter-sized spheres called chondrules, the major component of primitive meteorites. The study, by theorists Dr. Alan Boss of the Carnegie Institution and Prof. Richard H. Durisen of Indiana University, is published in the March 10, 2005, issue of The Astrophysical Journal (Letters)....
