Chelyabinsk Meteorite Had Close Encounter In Space Prior To Earth Impact
2013-08-27 06:59:32

Lawrence LeBlond for redOrbit.com - Your Universe Online The Chelyabinsk meteor that exploded over Russia’s Ural Mountains region earlier this year was found to have either collided with another celestial body or had a close encounter with the sun prior to reaching Earth. Researchers from the Institute of Geology and Mineralogy (IGM) in Novosibirsk, Russia announced today fragments of the Chelyabinsk meteorite – the main body that fell to the bottom of Chebarkul Lake near...

Early Solar System Garnet-like Mineral Named After Ian Hutcheon
2013-08-13 15:20:30

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...

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...

Moon's Water Supply Came From Earth, Not From Comet Impacts
2013-05-09 13:34:08

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Prior to the Apollo Moon missions, scientists conjectured that the Moon would be extremely dry, that even below the surface of the Magnificent Desolation little or no water would be present. But the rocks brought back by the lunar explorers revealed that the Moon, while still dry compared to Earth, contained a surprising amount of water. Furthermore, the composition of the Moon led scientists to the current Big Impact...

Meteorite Origins May Point To Mercury, Experts Still Puzzled
2013-04-06 05:57:24

redOrbit Staff & Wire Reports - Your Universe Online A stone originally discovered last year in Southern Morocco has been identified as a rare type of meteorite known as an achondrite, though its exact origin remains a mystery, according to experts from Washington University of St. Louis (WUSTL). The stone was one of 35 green-colored pieces discovered in early 2012. It was purchased by a dealer in the town of Erfound and then later resold to a German meteorite collector known as...

Is Oxygen's Role In Core Formation Underestimated?
2013-01-11 09:37:25

redOrbit Staff & Wire Reports - Your Universe Online The Earth´s core formed under more oxidizing conditions than previously believed, claims a new study published in Thursday´s edition of the journal Science Express. Lawrence Livermore National Laboratory (LLNL) geophysicist Rick Ryerson and an international team of colleagues made the discovery following a series of laser-heated diamond anvil cell experiments at high pressure (350,000 to 700,000 atmospheres) and...

Sutter's Mill Meteorite Under The Microscope
2012-12-21 05:32:02

Lee Rannals for redOrbit.com - Your Universe Online A meteorite study has led scientists to believe that asteroid surfaces may be more complex than previously thought. Scientists from around the world have come together to work on a meteor analysis of the Sutter's Mill meteorite that fell down to Earth in April 2012. The scientists reported in the journal Science that this particular meteor is an unusual example from a rare group known as carbonaceous chondrites. Samples from this...

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
2012-06-27 09:42:28

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...

Image 1 - Lutetia Found To Be A Rare Survivor From Earth's Birth
2011-11-11 11:03:39

[ Watch the Video ] New observations indicate that the asteroid Lutetia is a leftover fragment of the same original material that formed the Earth, Venus and Mercury. Astronomers have combined data from ESA´s Rosetta spacecraft, ESO´s New Technology Telescope, and NASA telescopes. They found that the properties of the asteroid closely match those of a rare kind of meteorites found on Earth and thought to have formed in the inner parts of the Solar System. Lutetia must, at some...

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...
