Latest Impact crater Stories
Scientists are backing up a theory, claiming that the Moon was created when a planetary body the size of Mars collided with Earth.
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.
In honor of 1,000 days in orbit, the NASA Lunar Reconnaissance Orbiter (LRO) team at NASA Goddard Space Flight Center in Greenbelt Md. has released two new videos.
Dust avalanches around impact craters on Mars appear to be the result of the shock wave preceding the actual impact, according to a study led by an undergraduate student at the UA.
NASA's MESSENGER spacecraft has discovered strange hollows on the surface of Mercury.
Scientists at Purdue University and Imperial College London have revised their popular â€˜Impact Effects Calculatorâ€™, which allows anyone to calculate the potential damage a comet or asteroid would cause if it collided with the Earth.
GREENBELT, Md., Sept.
The moon was bombarded by two distinct populations of asteroids or comets in its youth, and its surface is more complex than previously thought.
Saturn's moon Mimas -- Mimas is a moon of Saturn that was discovered in 1789 by William Herschel. Mimas' low density (1.17) indicates that it is composed mostly of water ice with only a small amount of rock. Mimas' most distinctive feature is a colossal impact crater 130 km across, named Herschel after the moon's discoverer. Herschel covers almost 1/3 of the diameter of the entire moon; its walls are approximately 5 km high, parts of its floor measure 10 km deep, and its central peak...
Jupiter's Moon Callisto -- With a diameter of over 4,800 km (2,985 miles), Callisto is the third largest satellite in the solar system and is almost the size of Mercury. Callisto is the outermost of the Galilean satellites, and orbits beyonds Jupiter's main radiation belts. It has the lowest density of the Galilean satellites (1.86 grams/cubic centimeter). Its interior is probably similar to Ganymede except the inner rocky core is smaller, and this core is surrounded by a large icy...
