Lee Rannals for redOrbit.com — Your Universe Online In relative terms, the Earth is about to escape another asteroid impact on Thursday by the hair on its chin. Although it's not like the 14-story sized asteroid is going to be nearing so close to Earth that you will be getting a prime view of in it your backyard, it will be about 7.5 times the Moon's distance from our planet. The asteroid, which is between 625 and 1,400 feet across, is close enough to Earth to be classified a...

Dinosaur Extinction Event Wasn't The First
2012-09-06 07:58:40

April Flowers for redOrbit.com - Your Universe Online Sixty-five million years ago, the most studied mass extinction in Earth's history happened and the dinosaurs were wiped off the planet. A new study from the University of Washington, published in Palaeogeography, Palaeoclimatology, Palaeoecology, indicates that a separate extinction came shortly before that, triggered by volcanic eruptions that warmed the planet and killed life on the ocean floor. A six-mile wide asteroid slamming...

British Television Station Crashes Meteor In London Taxi
2012-07-05 05:18:33

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online Londoners may have been shocked to walk past a car with a meteor sunk into it last week, but the hoax was actually a part of an advertisement for Eden TV in Britain. Eden set up a scene in Covent Garden, London to catch the attention of the public, by displaying a meteor about half the size of a car, imbedded into a black taxi. The ruse was set up to promote the launch of Eden TV's Science Month, in...

Ancient Asteroid Crater Discovered
2012-06-29 14:19:28

DM Crumbliss for redOrbit.com — Your Universe Online Asteroid impact craters are found all over the Earth, but most are erased by erosion or covered by time. The date has moved a billion years back by the discovery of the oldest impact crater yet at 3 billion years old. The crater is 100 kilometers wide and is the result of an asteroid or comet impact. The crater was discovered near the Maniitsoq region of West Greenland by a team of scientists from the Geological Survey of...

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...

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...
