Image 1 - New Research Reveals Details About Earth's Asteroid Impacts
2012-04-25 13:53:40

Lee Rannals for RedOrbit.com Researchers are reporting in the journal Nature that tiny "spherules" embedded in layers of rock have given them details about Earth's asteroid impacts. According to the team, the spherules were created when asteroids crashed into the Earth, vaporizing rock that expanded into space as a giant vapor plume. Small droplets of molten and vaporized rock in the plume then condensed and solidified, falling back to Earth as a thin layer.  These particles...

Asteroid Craters On Earth Give Clues In Search For Life On Mars
2012-04-18 03:09:30

Craters made by asteroid impacts may be the best place to look for signs of life on other planets, a study suggests. Tiny organisms have been discovered thriving deep underneath a site in the US where an asteroid crashed some 35 million years ago. Scientists believe that the organisms are evidence that such craters provide refuge for microbes, sheltering them from the effects of the changing seasons and events such as global warming or ice ages. The study suggests that crater sites...

New Evidence Suggests Comets Carried Life To Earth
2012-03-28 12:49:56

New evidence has come up that supports the idea that comets bombarding Earth billions of years ago carried and deposited the key ingredients for life. Scientists reported at the 243rd National Meeting & Exposition of the American Chemical Society (ACS) that the research is part of a broader scientific effort to understand how amino acids and other ingredients for the first living things appeared on Earth billions of years ago. The team used laboratory "guns" and computer models to...

Engineers Working Towards Laser Deflection Of Asteroids

Protecting the Earth from an extinction-threatening asteroid has in the past been left up to Hollywood, which has deployed a barrage of special effects box office blockbusters that have kept deadly space rocks from smashing our planet into oblivion. But now, Scottish engineers have come up with a plausible way of dealing with asteroids that doesn´t include Hollywood special effects. Engineers at the University of Strathclyde in Glasgow are developing an innovative technique based on...

Moon's Magnetic Anomalies May Be The Result Of Asteroid Collision
2012-03-09 03:06:00

In the nearly five decades since the first lunar surveys were conducted as part of NASA's Apollo program, scientists have advanced a number of increasingly complex theories to explain the vast swaths of highly magnetic material that had been found in the some parts of the Moon's crust. But now a team of researchers from Harvard, MIT and the Institut de Physique du Globe de Paris, have proposed a surprisingly simple explanation for the unusual findings — the magnetic anomalies are...

Image 1 - Meteorite Shockwaves Cause Martian Dust Avalanches
2011-12-17 05:00:03

Dust avalanches around impact craters on Mars appear to be the result of the shock wave preceding the actual impact, according to a study led by an undergraduate student at the UA When a meteorite careens toward the dusty surface of the Red Planet, it kicks up dust and can cause avalanching even before the rock from outer space hits the ground, a research team led by an undergraduate student at the University of Arizona has discovered. "We expected that some of the streaks of dust that...

Princeton Model Shows Fallout Of Giant Meteorite Strike
2011-10-20 04:50:33

Seeking to better understand the level of death and destruction that would result from a large meteorite striking the Earth, Princeton University researchers have developed a new model that can not only more accurately simulate the seismic fallout of such an impact, but also help reveal new information about the surface and interior of planets based on past collisions. Princeton researchers created the first model to take into account Earth's elliptical shape, surface features and ocean...

Geologists Assess Deep Impacts Of Near-Earth Object Strikes
2011-10-18 08:03:44

Volcanologists from the Universities of Leicester and Durham have forensically reconstructed the impact of a meteorite on Earth and how debris was hurled from the crater to devastate the surrounding region. New research by Mike Branney, of the University of Leicester's Department of Geology, and Richard Brown, University of Durham, shows that some aspects of giant meteorite impacts onto Earth may mimic the behavior of large volcanic eruptions. Meteorite impacts are more common than is...

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...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...
