Latest Allende meteorite Stories
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.
Hutcheonite, recently named after Lawrence Livermore meteorite researcher Ian Hutcheon, can be seen only with high powered scanning electron microscopes.
New research suggests that meteorites, and their parent asteroids, are most-likely the sources of Earth's water.
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.
Scientists have found that 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.
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.
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.

What could happen if a 25-million-ton chunk of rock slammed into Earth?
When Tony Garchinski heard a loud crash just after 9 pm on Friday, September 25 he didnâ€™t think much of it.
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.
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...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
