Momentum Grows for First Private Deep Space Mission to Map the Inner Solar System and Track Asteroids Posing Threats to Earth
Around 2.5 million years ago, a huge meteor collided with the Earth and fell into the southern Pacific Ocean. A new study suggests that not only could this have caused a massive tsunami, but it may also have plunged the world into the Ice Ages.
In relative terms, the Earth is about to escape another asteroid impact on Thursday by the hair on its chin.
Sixty-five million years ago, the most studied mass extinction in Earth's history happened and the dinosaurs were wiped off the planet, but a new study indicates that a separate extinction came shortly before that.
Londoners may have been shocked to walk past a car with a meteor sunk into it last week, but the hoax was actually a part of an advertisement for Eden TV in Britain.
Asteroid impact craters are found all over the Earth, but most are erased by erosion or covered by time. The date has moved a billion years back by the discovery of the oldest impact crater yet at 3 billion years old.
Researchers are reporting in the journal Nature that tiny "spherules" embedded in layers of rock have given them details about Earth's asteroid impacts.
Craters made by asteroid impacts may be the best place to look for signs of life on other planets, a study suggests.
New evidence has come up that supports the idea that comets bombarding Earth billions of years ago carried and deposited the key ingredients for life.
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...
