Latest Impact event Stories
A remarkable discovery was made by astronomers on 12 December 2010: an asteroid named Scheila had changed its appearance and looked more like a comet, complete with bright tail.
According to a new study published in the journal Nature on Wednesday, the Earth's ocean may have been created by comets.
New asteroid population numbers given by NASA shows that Earth isn't as threatened as previously thought by the space rocks.
Precious metals such as gold, platinum and tungsten were brought to Earth by a massive meteorite shower that occurred approximately 650 million years after the planet formed.
Computer models of asteroid impact debris from Earth to other planets show 100 times more particles end up on Mars than prior studies have shown.
The debate whether dinosaurs went extinct due to a large space rock that struck the Earth over 65 million years ago may have been answered with the discovery of a distinctive brow horn from a Ceratopsian dinosaur just 13 centimeters below the K-T boundary.
According to a new discovery, some asteroids may have been like "molecular factories" cranking out life's ingredients and shipping them to Earth through meteorite impacts.
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...
