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.
Samples of moon rocks brought back by the Apollo astronauts are a gift that just keeps on giving, and a new study has shed more light on the fact that the moon once had its own magnetic field, just like the Earth has today.
Previous research has indicated that Earth has lost its atmosphere at least twice since being formed, and a new study has indicated that a bombardment of tens of thousands of space rocks could have been behind the phenomenon.
Back in 1971, Apollo 15 astronauts orbiting the Moon photographed something very odd. Researchers called it "Ina," and it looked like the aftermath of a volcanic eruption.
In an address to Congress in 1961, President John F. Kennedy challenged the nation to "land a man on the moon and return him safely to Earth" before the end of the decade. With the flight of Apollo 12, 45 years ago this month, NASA achieved that goal a second time.
NASA’S Lunar Reconnaissance Orbiter (LRO) spacecraft has spied a new crater on the lunar surface; one made from the impact of NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) mission.
NASA's Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon's volcanic activity slowed gradually instead of stopping abruptly a billion years ago.
They are the darkest and coldest places on the surface of the moon, but deep in the craters of the polar regions, electrical activity may be creating a kind of “sparking” that has driven changes in lunar soil evolution.
Over four billion years ago, giant asteroid impacts collided with the Earth’s surface and gave the planet a facelift of sorts – mixing, burying and melting the landscape, according to a new terrestrial bombardment model devised by an international team of researchers.
The Hadean is the unofficial geological period of time that lies just before the Archean time period. The Hadean began with the formation of the Earth roughly 4.5 billion years ago (Ga) and ended about 3.8 Ga; the latter date varies according to different sources. Hadean is derived from Hades, Greek for “underworld,” referring to the hellish conditions on the planet at the time. The term was coined in 1972 by geologist Preston Cloud. The period was later classified as the “Priscoan...
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...
The Moon -- The Moon is the largest satellite of the Earth, and is occasionally called Luna (Latin for moon) to distinguish it from the general use of the word "moon". The Moon is distinguished from the satellites of other planets by its initial capital letter; the other moons are described in the natural satellite article. The words moon and month come from the same Old English root word. The Moon makes a complete orbit of the celestial sphere about every four weeks. Each hour the...
The Moon -- natural satellite of a planet, in particular, the single natural satellite of the earth. The Earth-Moon System The moon is the earth's nearest neighbor in space. In addition to its proximity, the moon is also exceptional in that it is quite massive compared to the earth itself, the ratio of their masses being far larger than the similar ratios of other natural satellites to the planets they orbit (with the exception of Charon and Pluto). For this reason, the...
