Latest Impact event Stories
Near-Earth asteroid 2005 YU55 was "imaged" by the Arecibo Radar Telescope in Puerto Rico on April 19.
For decades, scientists have accumulated ever-larger datasets that suggest an enormous space rock crashed into the ocean off the Yucatan Peninsula more than 65 million years ago, resulting in the Cretaceous-Paleogene (K-Pg) extinction.
A new report from the National Research Council lays out options NASA could follow to detect more near-Earth objects (NEOs) â€“ asteroids and comets that could pose a hazard if they cross Earth's orbit.
An international team of scientists led by researchers at the University of Hawaii at Manoa have found no evidence supporting an extraterrestrial impact event at the onset of the Younger Dryas ~13000 years ago.
A mysterious basin off the coast of India could be the largest, multi-ringed impact crater the world has ever seen. And if a new study is right, it may have been responsible for killing the dinosaurs off 65 million years ago.
Using updated information, NASA scientists have recalculated the path of a large asteroid. The refined path indicates a significantly reduced likelihood of a hazardous encounter with Earth in 2036.
A 17-member team has found what may be the smoking gun of a much-debated proposal that a cosmic impact about 12,900 years ago ripped through North America and drove multiple species into extinction.
The enduringly popular theory that the Chicxulub crater holds the clue to the demise of the dinosaurs, along with some 65 percent of all species 65 million years ago, is challenged in a new paper published Monday.
The European Space Agency says scientists are getting ready for an international meeting to discuss preparations for a near-Earth flyby of asteroid Apophis. The first International Academy of Astronautics Planetary Defense Conference will be held in Granada, Spain, next week.
For the first time in history, scientists have matched a meteorite on Earth with a specific asteroid, providing insight into how the planets were formed and how to best avoid a potential asteroid catastrophe sometime in the future.
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...
