Theia Collision With Earth To Form The Moon
2012-08-30 10:16:41

April Flowers for redOrbit.com - Your Universe Online Around 4.5 billion years ago, the Earth is believed to have collided with an impactor the size of Mars known as "Theia." This collision, current theory says, is what formed the Moon. Scientists have simulated this formation process and reproduced many of the Earth-Moon system properties. However, these simulations have also given rise to a problem known as the Lunar Paradox. According to the Paradox, the Moon seems to be made up of...

LRO Finds Traces Of Helium Around The Moon
2012-08-16 05:19:20

April Flowers for redOrbit.com - Your Universe Online Using the Lyman Alpha Mapping Project (LAMP) spectrometer aboard NASA's Lunar Reconnaissance Orbiter (LRO), scientists have made the first spectroscopic observations of the noble gas helium in the atmosphere surrounding the Moon. These remote-sensing observations complement the situ measurements taken in 1972 by the Lunar Atmosphere Composition Experiment (LACE) deployed by Apollo 17. LAMP was originally designed to map the lunar...

Moon Formation From Giant Hit-and-run Impact
2012-07-30 04:42:40

redOrbit Staff & Wire Reports - Your Universe Online While scientists tend to accept the theory that the Moon was formed following a collision between a young Earth and a second planet, new research published online earlier this month suggests that the impactor might have been larger and traveling faster than previously believed. Current theory suggests that Earth's satellite was formed when the protoplanet was hit by a second world, believed to have been about the size of Mars,...

Iapetus Ice Avalanches Explain Landslides Elsewhere
2012-07-30 04:26:15

Lee Rannals for redOrbit.com - Your Universe Online Researchers from Washington University in St. Louis, Missouri have found that giant ice avalanches on Saturn's moon Iapetus could provide clues to slippage in other places in the Solar System. Kelsi Singer, graduate student in Earth and planetary sciences in Arts & Sciences at the university, says that landslides take place everywhere in the Solar System, but Iapetus has more giant landslides than any celestial body in our...

New Research Better Understands Lunar Swirls
2012-07-19 13:42:14

Lee Rannals for redOrbit.com - Your Universe Online A study of "lunar swirls" on the moon may eventually lead to new developments in engineering to help protect astronauts in space. During the Apollo missions, scientists realized that lunar swirls were associated with localized magnetic fields in the lunar crust. NASA's Lunar Prospector focused on the regions and identified magnetic anomalies that had created fully formed miniature "magnetospheres" similar to what the Earth's...

Ancient Asteroid Crater Discovered
2012-06-29 14:19:28

DM Crumbliss for redOrbit.com — Your Universe Online 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. The crater is 100 kilometers wide and is the result of an asteroid or comet impact. The crater was discovered near the Maniitsoq region of West Greenland by a team of scientists from the Geological Survey of...

Weird Lunar Soil Behaviour Explained With Nanoparticles Found In Moon Glass Bubbles
2012-06-13 15:48:29

A stunning discovery by QUT soil scientist Marek Zbik of nano particles inside bubbles of glass in lunar soil could solve the mystery of why the moon's surface topsoil has many unusual properties. Dr Zbik, from Queensland University of Technology's Science and Engineering Faculty, said scientists had long observed the strange behavior of lunar soil but had not taken much notice of the nano and submicron particles found in the soil and their source was unknown. Dr Zbik took the lunar...

Lee Rannals for redOrbit.com Researchers from the University of Colorado in Boulder have cataloged over 635,000 Martian craters. The research team just recently finished up counting, outlining and cataloging the 635,000 impact craters on Mars that are roughly a half-mile in diameter. “This database is a giant tool that will be helpful in scores of future Mars studies ranging from age-dating and erosion to planetary habitability and to other applications we have not even thought...

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...
