April Flowers for redOrbit.com - Your Universe Online An ocean of molten rock covered the entire lunar surface during the early part of the Moon's history. Over millions of years, that magma ocean cooled, differentiating to form the crust and mantle. According to new analysis of NASA's Lunar Orbiter Laser Altimeter (LOLA) data, led by Brown University planetary scientists, this wasn't the last time the Moon's surface melted on such a massive scale. Graduate student William Vaughan led...

Nature of mysterious hot spot revealed by "photogeology" By Diana Lutz, Washington University in St. Louis Analysis of new images of a curious "hot spot" on the far side of the Moon reveal it to be a small volcanic province created by the upwelling of silicic magma. The unusual location of the province and the surprising composition of the lava that formed it offer tantalizing clues to the Moon's thermal history. The hot spot is a concentration of a radioactive element thorium sitting between...

The Moon's geological past could be better understood by a mineral that Japanese astronomers report they have found. Using an instrument-loaded probe - Kaguya - placed in orbit around the lunar body in 2007, the team of scientists found abundant sources of the mineral in concentric rings in three distinct crater regions. Olivine, as the mineral is known, is believed to be a revealing sign of mantle -- the deep inner layer of iron- and magnesium-rich rock that lies beneath the Moon's crust....

A new study by NASA-funded scientists at the Carnegie Institution's Geophysical Laboratory finds that the interior of the moon may hold 100 times more water than previously believed. The scientists analyzed samples of moon rocks collected by Apollo astronauts nearly four decades ago, and found that the volume of water molecules inside minerals in the moon's interior could exceed that of the entire U.S. Great Lakes.  The researchers concluded that the water was likely preserved from...

WASHINGTON, June 14 /PRNewswire-USNewswire/ -- NASA-funded scientists estimate from recent research that the volume of water molecules locked inside minerals in the moon's interior could exceed the amount of water in the Great Lakes here on Earth.

ALBUQUERQUE (AP) -- University of New Mexico researchers have identified a 2.9 billion-year-old lunar meteorite, the youngest dated lunar rock. "It was a little piece of rock containing various minerals," said earth and planetary sciences department senior research scientist Lars Borg. "It's not much different than what's on earth." UNM's sample, obtained from the Natural History Museum in London, was named Northwest Africa 773, or NWA 773, to describe where it was found in 2000. NWA 773...

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...
