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...

Lawrence LeBlond for redOrbit.com - Your Universe Online Initial reports put last Friday´s (Feb 15) Chebarkul meteorite that exploded over Russia´s Urals region at about 10 tons. But after careful analysis, NASA released new information that puts the meteorite closer to 10,000 tons–1,000 times larger than the estimated size reported by the Russian Academy of Sciences (RAS). “My guess is that someone eyeballed the videos and made an educated guess,” said...

Researchers sifting through Google Earth images have discovered what may be the world's best-preserved small impact crater in a remote area of the Sahara desert in southwestern Egypt.   The immaculate, 148 ft. wide crater was likely excavated by a fast-moving iron meteorite, a few thousand years ago, scientists said Thursday. Dubbed Kamil, the crater is remarkably preserved when compared with most of the other craters on the Earth's surface, many of which are partially eroded. The...

Australian scientists announced Thursday that they have discovered a crater deep beneath the Timor Sea made during a heavy meteor storm, which may have altered the Earth's climate. Australian National University archaeologist Andrew Glikson said seismic activity led experts to the Mount Ashmore 1B site, and a fragment study found that a large meteorite hit the area just before the Earth's temperatures dropped. "The identification of microstructural and chemical features in drill fragments...

A Wisconsin man said a hunk of metal he bought from a rummage sale years ago turned out to be a stolen meteorite that fell to Earth about 50,000 years ago. Tom Lynch, 62, of South Milwaukee, said he had no idea the 50-pound piece of metal was a meteorite until he saw a special about the objects on the Travel Channel, the Milwaukee Journal Sentinel reported Wednesday. For the last two years, it kept my grandson's basketball hoop from blowing over in the yard. It weighs 50 pounds, Lynch said....

Arizona -- The iron meteorite that blasted out Meteor Crater almost 50,000 years ago was traveling much slower than has been assumed, University of Arizona Regents' Professor H. Jay Melosh and Gareth Collins of the Imperial College London report in the cover article of Nature (March 10). "Meteor Crater was the first terrestrial crater identified as a meteorite impact scar, and it's probably the most studied impact crater on Earth," Melosh said. "We were astonished to discover something...

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...

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...
