[ Watch the Video: Origins Of Moon's Water Explored ] John P. Millis, PhD for redOrbit.com - Your Universe Online Recent studies by NASA and the European Space Agency (ESA) have found that the Moon is wetter than previously thought - though it is still drier than the driest desserts on Earth. In turn, this has generated renewed interest in identifying the source of this water. Now, a team from The Open University in the United Kingdom has found that a young, still forming Earth may...

Sutter's Mill Meteorite Considered Scientific Gold

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...

Earliest Known Egytpian Iron Jewelry Derived From Outer Space
2013-08-20 07:21:37

Lawrence LeBlond for redOrbit.com - Your Universe Online Some of the earliest pieces of jewelry discovered have been found to contain samples from outer space. Archaeologists have confirmed funeral beads strung around bodies from a 5000-year-old Egyptian cemetery contained pieces of iron from meteorites that fell to Earth. Using high-tech scanning methods, researchers from University College London (UCL) found the nine small beads, which were discovered in the Lower Egypt village of...

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...

Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief has disappeared leaving only a...
