2013-10-08 14:28:15

[ Watch the Video: Ancient Earth Comet Impact Evidence ] Lee Rannals for redOrbit.com - Your Universe Online Comet ISON is getting closer to making its close pass by the sun, but what would happen if it had a brush with our planet instead? New evidence shows it would be devastating. International scientists have discovered the first ever evidence of a comet entering Earth's atmosphere and exploding. This celestial object rained down fire across the Earth, obliterating every life form...

Origin Of Moon Water

[ 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
2013-09-11 05:44:09

April Flowers for redOrbit.com - Your Universe Online Researchers from Arizona State University (ASU) have made an important discovery about the possible inventory of molecules available to the early Earth. Sandra Pizzarello, a research professor in ASU's Department of Chemistry and Biochemistry, led the team in examining the Sutter's Mill meteorite - which exploded in a blazing fireball over California last year - to find that it contains organic molecules not previously found in any...

Fireball Over Tennessee And Georgia

[ Watch The Video: Bright Meteor Captured Over Georgia/Tennessee ] Brett Smith for redOrbit.com - Your Universe Online Typically, there isn’t much to see in the predawn hours of a Wednesday morning in the Southeast US. However, on August 28, those who happened to be awake and outside at 3:27 a.m. in northern Georgia and Tennessee were treated to the spectacle of a short-lived yet massive fireball that out-shown the moon. “Recorded by all six NASA cameras in the Southeast, this...

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...

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...

Martian Meteorite Age Puzzle Solved
2013-07-25 04:47:27

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Occasionally, a meteorite is found on Earth with peculiar origin: Mars. Anytime a large object such as an asteroid or comet impacts the surface of Mars, chunks of rock are ejected into outer space. Over time, some of these stones will make their way to Earth, impacting the ground as meteorites. We know that these specimens are from Mars based on their composition and other factors. So they provide an excellent laboratory for...

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...

Russian Meteor Produced A Shockwave That Traveled The Globe Twice
2013-06-28 07:07:05

Lawrence LeBlond for redOrbit.com - Your Universe Online The Chelyabinsk meteor that blazed a trail across the morning sky in Russia this past February left a shocking impact on not just the Ural Mountains region, but the entire world. A new report published in the journal Geophysical Research Letters states the shockwave from the meteoric explosion on the morning of February 15, 2013 traveled around the globe -- not once, but twice. Scientists, led by Alexis Le Pichon of the French...

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...
