Eric Hopton for redOrbit.com - Your Universe Online 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. New information about these areas could lead to greater understanding of planetary surfaces in the solar system. To the scientists studying data from the Lunar Reconnaissance Orbiter (LRO), the moon is a giant...

artistic conception of the early Earth

redOrbit Staff & Wire Reports - Your Universe Online 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 from various academic and government institutions. The new model was based on existing lunar and terrestrial data, and according to the authors of a new paper...

Mare Tranquillitatis pit crater

Bill Steigerwald, NASA's Goddard Space Flight Center While the moon's surface is battered by millions of craters, it also has over 200 holes – steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for shelter, according to new observations from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft. The pits range in size from about 5 meters (~5 yards) across to more than 900 meters (~984 yards) in diameter, and three of them were first...

Astronauts Visiting Moon Will Not Find Water On The Sunny Side
2014-06-17 13:26:25

Brett Smith for redOrbit.com - Your Universe Online Astronauts looking to lay the groundwork for a future settlement or station on the Moon will be looking for water to use as a resource. According to a new study, however, they may want to save some time by not looking for it on areas of the Moon that are exposed to the Sun. Published in the Journal of Geophysical Research: Planets, the study found that ultraviolet photons released by the Sun probably result in water molecules to either...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Despite being the nearest astronomical object to Earth, and the only extraterrestrial site of human visitors, the Moon still contains mysteries that have puzzled scientists for the better part of a century. Perhaps the greatest question surrounding lunar history is its two-faced nature. Due to the mutual gravitational interaction of the Earth-Moon system, the giant satellite is tidally locked with our planet, so we always see...

moon formation collision theory

redOrbit Staff & Wire Reports - Your Universe Online The Moon was most likely formed by a collision between the Earth and a planet-sized object that took place roughly 4.5 billion years ago, a team of German scientists report in research published Friday by the journal Science. According to the Associated Press (AP), the study authors took an in-depth look at moon rocks that had been gathered during the Apollo 11, 12 and 16 missions. They discovered that moon rocks have a different...

Alan McStravick for redOrbit.com - Your Universe Online Growing up, we all learned about how the tides of our oceans, seas and large lakes are caused by the moon. The explanation given us had to do with the effect of gravity that the heavenly body had on the fluid surfaces of our planet. It would make sense that Earth's gravity would also have an effect on the moon, save its solid surface. In fact, there is such thing as a lunar body tide. Today, thanks to the combination of observations...

redOrbit Staff & Wire Reports - Your Universe Online By reviewing hundreds of chemical analyses of lunar samples collected during the Apollo missions, scientists have discovered new clues about how water originated and was redistributed on the Moon, according to a recently published Nature Geoscience paper. Their findings could give experts a new tool to help unravel the processes that were involved in the Moon’s formation, as well as how the lunar crust cooled and the impact...

asteroid impact
2014-04-10 08:39:56

Brett Smith for redOrbit.com - Your Universe Online Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa. Now, a new study published in the journal Geochemistry, Geophysics, Geosystems has outlined the details surrounding that massive impact, such as the creation of a crater about 300 miles across and...

redOrbit Staff & Wire Reports - Your Universe Online Using new data obtained by the MESSENGER spacecraft, researchers from Brown University in Rhode Island have discovered that explosive volcanic activity has been occurring throughout most of Mercury’s history, meaning that the planet has had the volatile compounds necessary for those eruptions for longer than anticipated. The findings, which are detailed in a recent edition of the Journal of Geophysical Research: Planets, are...

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...
