Latest Impact event Stories
Asteroid impacts on Earth – those on the scale of the one that wiped out the dinosaurs 65 million years ago – have been big hits in Hollywood. But in the modern world, are the impacts portrayed in movies like Deep Impact and Armageddon only the stuff of science fiction?
The discovery of biodata encapsulated in molten glass resulting from asteroid and comet impacts millions of years ago not only provides information about the climate and life forms of the ancient Earth, but has also led to hopes that similar preserved organic compounds will be discovered on Mars.
Small asteroids contain a layer of loose, unconsolidated rock and dust known as a regolith composed of centimeter-sized fragments and smaller particles.
The Moon Impacts Detection and Analysis System (MIDAS) has helped take a video of the Man in the Moon getting nailed by an asteroid.
NASA released a new video showing how its MAVEN mission will be able to look back at the history of the Red Planet.
Astronomers working at the Crimean Astrophysical Observatory in Ukraine found a new asteroid on October 13, 2013 and NASA confirmed it came within about 4.2 million miles of Earth on September 16. New estimates predicts a slight chance of impact in 2032.
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 has happened before and another would be devastating.
Earth’s closest neighbor, the moon, has been studied intently by astronomers for centuries. In that time, we thought we had discovered nearly everything there is to know about the origins of our natural satellite.
A new study has found that a cataclysmic asteroid or comet impact in the Canadian province of Quebec nearly 13,000 years ago wiped out many of the world’s large mammals.
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...
