Latest Impact crater Stories
The presence of a diverse group of minerals in the largest lunar impact crater could help scientists gain new insight into the Moon’s interior, as well as the evolution of its crust and mantle, claims new research appearing online in Journal of Geophysical Research: Planets.
USGS hydrologists drilling into the largest crater in the country have stumbled across an amazing discovery – the oldest body of seawater ever unearthed.
NASA released a new video showing how its MAVEN mission will be able to look back at the history of the Red Planet.
Scientists have long believed that the moon’s trademark craters were created from the impact of massive asteroids, but new research suggests that smaller planetoids might actually have been responsible for pummeling the lunar surface.
Earth’s closest neighbor, the moon, has been studied intently by astronomers for centuries. In that time, we thought we had discovered nearly everything there is to know about the origins of our natural satellite.
A meteor from 470-million-years-ago lies buried several hundred feet beneath the town of Decorah, Iowa, according to an airborne geophysical survey reported in EARTH Magazine.
According to an analysis of images provided by NASA's Mercury-orbiting MESSENGER, a period of heavy volcanic activity gave Mercury a makeover about 4 billion years ago, erasing the first 400 to 500 million years of its history.
Researchers from Purdue University and MIT have solved the long-standing mystery of why the moon’s gravitational force is stronger in some areas than in others.
Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA’s Mars Express on 4 January.
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...
