Latest Impact event Stories
At a major planetary defense conference in Flagstaff, AZ, last evening, the Planetary Society announced the winners of its 2013 Shoemaker Near Earth Object (NEO) grants and was recognized itself for the Society’s long history of international leadership in the detection and mitigation of threatening asteroids, and other planetary discoveries.
Researchers claim to have uncovered new evidence supporting the notion that a Manhattan-sized asteroid collided with the Earth some 66 million years ago, triggering a global firestorm that would have led to the extinction of 80 percent of the planet’s species.
According to Jason Moore from Dartmouth College, who presented a study at the 44th Lunar and Planetary Science Conference, evidence from the Chicxulub crater suggests there are possibilities beyond an asteroid impact.
The giant Chicxulub crater in Yucatan is evidence that sometime around 65 million years ago a massive asteroid smashed into the earth wiping out most life that existed at that time, including all non-avian dinosaurs. While it is hard to imagine a similar scenario taking place today, there is currently little that we could do but sit and “pray.”
A researcher in Aerospace Engineering at the University of Southampton has released the results of a simulation of the Chelyabinsk meteor using high-tech software called NEOImpactor.
With all the recent meteor events, such as last Friday’s that exploded over Russia, injuring more than a thousand people, and the possible smaller explosion over Cuba just a day later, many may be wondering if similar events have occurred in their neck of the woods anytime in the past.
The first firm details of the 15 February asteroid impact in Russia, the largest in more than a century, are becoming clear.
Just one day after a spectacular meteor exploded over Russian skies, shattering windows and injuring more than a 1,200 people, Cubans were treated to a similar event, albeit on a much smaller scale.
A massive asteroid that crashed into Earth left behind a large impact crater in Australia and changed the entire landscape of the planet.
A meteor streaked across Russia’s early morning skies on Friday before violently exploding, sending a rain of debris onto the Earth below. The flash and boom shattered windows and meteor particles left damage in its wake, injuring more than 900 people in the Ural Mountains region.
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 Î”V 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...
