Earthen Crust Oxygen Got Its Start During Creation Of Solar System
2013-10-25 07:03:56

April Flowers for redOrbit.com - Your Universe Online A long standing mystery in the formation of the Solar System has been solved by cosmochemists from the University of California, San Diego (UCSD). In the oldest, most pristine rocks, oxygen, the most abundant element in the Earth's crust, follows a strange, anomalous pattern that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth. "Whatever the source of...

Early Solar System Garnet-like Mineral Named After Ian Hutcheon

Lawrence Livermore National Laboratory A recently discovered mineral appears to be clear but may have a tinge of light blue. No matter its color, you won't be able to make earrings from it. For one, you can't see the material with the naked eye. Hutcheonite, recently named after Lawrence Livermore meteorite researcher Ian Hutcheon, can be seen only with high powered scanning electron microscopes. Known also by its chemical makeup, Ca3Ti2SiAl2O12, hutcheonite was discovered in a...

Lee Rannals for redOrbit.com - Your Universe Online New research suggests that meteorites, and their parent asteroids, are most-likely the sources of Earth's water. Scientists have believed that comets, or a primitive meteorite called carbonaceous chondrites, were the sources of earth Earth's volatile elements, including hydrogen, nitrogen, and carbon. Having an understanding of where these volatiles came from is crucial when determining the source of water and life on the planet....

Newly Discovered Mineral Provides Clues To Evolution Of Solar System

Lawrence LeBlond for redOrbit.com A previously unknown mineral has been found in a meteorite that fell to Earth in 1969, according to a Caltech geologist who has been studying the meteoric sample since 2007, and who has also found eight other new minerals in the sample. The Allende meteorite was among thousands of meteorites that lay scattered about the state of Chihuahua, in Mexico, after a meteor exploded over the region in 1969. More than 40 years later, the meteorite is providing...

Scientists have found that calcium, aluminum-rich inclusions (CAIs), some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the mid-plane of the solar system.The findings may lead to a greater understanding of how our solar system and possibly other solar systems formed and evolved.CAIs, roughly millimeter- to centimeter in size, are believed to have formed very early in the evolution of the solar system and had contact with nebular gas,...

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...

HOUSTON, March 3, 2011 /PRNewswire-USNewswire/ -- NASA research on a meteorite has provided new evidence that the inner planets formed from materials spread far and wide in the early solar system, and not just from nearby matter. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Oxygen isotopic measurements in the core and outer rim of a calcium-aluminum-rich inclusion contained in the Allende meteorite record the entire range of oxygen isotopic composition previously measured...

So you think global warming is a big problem? What could happen if a 25-million-ton chunk of rock slammed into Earth? When something similar happened 65 million years ago, the dinosaurs and other forms of life were wiped out."A collision with an object of this size traveling at an estimated 30,000 to 40,000 mile per hour would be catastrophic," according to NASA researcher and New York City College of Technology (City Tech) Associate Professor of Physics Gregory L. Matloff. His...

When Tony Garchinski heard a loud crash just after 9 p.m. on Friday, September 25 he didn't think much of it. That is, until he awoke the next morning to find the windshield of his mom's Nissan Pathfinder with a huge crack in it. Making note of the "Ëœunusual' rocks he later found on the car's hood, Garchinski chalked the incident up to vandalism and filed a police report. It wasn't until two weeks later that his mother, Yvonne Garchinski, heard media reports that researchers from...

Researchers have discovered an unusual kind of meteorite in the Western Australian desert and have uncovered where in the Solar System it came from, in a very rare finding published today in the journal Science. Meteorites are the only surviving physical record of the formation of our Solar System and by analyzing them researchers can glean valuable information about the conditions that existed when the early Solar System was being formed. However, information about where individual...

Meteorite -- A meteorite is a relatively small extraterrestrial material body that reaches the Earth's surface. While in space these bodies are called meteoroids. Upon entering the atmosphere air drag and friction will cause the body to heat up, emitting light, thus forming a meteor, fireball, or shooting star. Most meteors disintegrate in the air, making impact events (Earth impacts) on the surface of Earth uncommon. About 500 baseball sized rocks a year reach the surface. Large...
