Latest Impact event Stories
A nearly 250 mile (400 km) wide impact zone recently discovered in Central Australia is being called the largest asteroid-caused craters ever discovered, according to research published earlier this month in the international earth sciences journal Tectonophysics.
Researchers from the University of California, Davis have found new evidence discrediting a controversial theory that a cosmic impact caused a thousand-year period of cold that coincided with the extinction of mammoths and other massive creatures.
Ever wonder what the formation of an asteroid crater on Earth would look like if viewed in slow-motion? Researchers from the University of Minnesota have found a unique way to model such an event by recording the impact of raindrops on sandy surfaces.
A map released Nov. 14, 2014 by NASA's Near Earth Object (NEO) Program reveals that small asteroids frequently enter and disintegrate in the Earth's atmosphere with random distribution around the globe.
WASHINGTON, Nov. 7, 2014 /PRNewswire-USNewswire/ -- Two NASA and one European spacecraft that obtained the first up-close observations of a comet flyby of Mars on Oct.
A tiny fragment of Martian meteorite 1.3 billion years old is helping to make the case for the possibility of life on Mars, say scientists.
A new study published in The Journal of Geology provides support for the theory that a cosmic impact event over North America some 13,000 years ago caused a major period of climate change known as the Younger Dryas stadial, or “Big Freeze.”
Nicaraguan officials reported Sunday that the impact of a small meteorite had left a nearly 40-foot crater near the airport of the capital city of Managua, but US scientists are casting doubts on those claims.
Researchers at the University of Tennessee at Knoxville have made a novel discovery that may potentially protect the world from future collisions with asteroids.
Seven years ago, the Bunburra Rockhole Meteorite fell on the Western Australia side of Nullarbor Plain and was captured on camera. A new study indicates that the unique characteristics of the meteorite suggest it originates from a never-before-identified asteroid.
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...
