  Moon Phases :: Calendars
The phases of the moon are caused by the relative positions of the earth, sun, and moon.
When the moon is between the earth and the sun, it appears dark, a "new" moon.
Because the "horns" of the moon at the ends of the crescent are always facing away from the setting or rising sun, they always point upward in the sky.

  Moon - MSN Encarta
The Moon is the second brightest object in Earth’s sky, after the Sun, and has accordingly been an object of wonder and speculation for people since earliest times.
The average density of the Moon is only three-fifths that of Earth, and gravity at the lunar surface is only one-sixth as strong as gravity at sea level on Earth.
The Moon rotates once on its axis in the same period of time that it circles Earth, accounting for the fact that virtually the same portion of the Moon (the “near side”) is always turned toward Earth.

  Moon - Wikipedia, the free encyclopedia
The first man-made object to land on the Moon was Luna 2 in 1959; the first photographs of the otherwise occluded far side of the Moon were made by Luna 3 in the same year, and the first people to land on the Moon came aboard Apollo 11 in 1969.
Early speculation proposed that the Moon broke off from the Earth's crust due to centrifugal force, leaving an ocean basin (presumed to be the Pacific Ocean) behind as a scar.

The moon rotates on its axis once in about the same period of time that elapses for its sidereal period of revolution, accounting for the fact that virtually the same portion of the moon is always turned toward the earth.
The moon’s magnetic field is not as strong or widespread as that of the earth.
Hence the moon is still being bombarded by meteoroids, although not as often as in the past, and this may be a problem for engineers who design permanent bases for the lunar surface.

 Moon - Uncyclopedia
The Moon is a small penis that is actually a chode and dxrvdbvgcfsvfesfrsfdefdd to photos of the moon on the sky approximately the size of an American quarter.
The moon is one of the figures primarily remembered for his work on the computer language LISP, but McCarthy got jealous of his powers and banished him to deep space, where he has since remained and collected a large amount random, subcutaneous steller cheese, a fact which is obvious to any four year old.
This misconception is caused by the fact that the moon, though made entirely of Stinking Bishop cheese and green food-grade dyes, is covered by a thick layer of dust due to being left in too high an orbit for Earth's janitorial staff to reach.

 Moon
The mass of the Moon is not evenly distributed; mass concentrations, called Mascons, lie beneath many of the lunar basins, and the center of mass of the Moon is displaced several kilometers towards the Earth.
The lack of atmosphere produces temperature extremes on the Moon that range from -250 degrees F in the dark to +250 degrees F in the light.
The lack of atmosphere means that there is no aerodynamic drag on a rocket leaving the surface of the Moon, but it also means that a landing spacecraft cannot use aerodynamic braking and must use rocket propulsion to land on the surface.

 The Moon
The Moon was heavily bombarded early in its history, which caused many of the original rocks of the ancient crust to be thoroughly mixed, melted, buried, or obliterated.
This false-color photograph of the Moon was taken by the Galileo spacecraft on December 8, 1992.
The footprints of the astronauts are clearly visible in the soil of the Moon.

 The Moon
The Moon's gravitational attraction is stronger on the side of the Earth nearest to the Moon and weaker on the opposite side.
Actually, the Moon appears to wobble a bit (due to its slightly non-circular orbit) so that a few degrees of the far side can be seen from time to time, but the majority of the far side (left) was completely unknown until the Soviet spacecraft Luna 3 photographed it in 1959.
There were three principal theories: co-accretion which asserted that the Moon and the Earth formed at the same time from the Solar Nebula; fission which asserted that the Moon split off of the Earth; and capture which held that the Moon formed elsewhere and was subsequently captured by the Earth.

 Curious About Astronomy? The Moon
This image of the Moon was taken by the Galileo spacecraft as it passed by.
The far side of the Moon is lighted part of the time and dark part of the time as well; hence it is incorrect to refer to it as the "dark side of the Moon" (sorry, Pink Floyd).
It is now believed that the Moon was created by re-accretion of fragments resulting from a collision between the Earth and one body the size of Mars, in the last phases of the formation of the Solar System.

 The Moon - Zoom Astronomy
The moon is a cold, dry orb whose surface is studded with craters and strewn with rocks and dust (called regolith).
Also, from any spot on the moon (except on the far side of the moon where you cannot see the Earth), the Earth would always be in the same place in the sky; the phase of the Earth changes and the Earth rotates, displaying various continents.
At its closest approach (the lunar perigee) the moon is 221,460 miles (356,410 km) from the Earth.

 The Galileo Project | Science | Moon
The heavens, starting at the Moon, were the realm of perfection, the sublunary region was the realm of change and corruption, and any resemblance between these regions was strictly ruled out.
He suggested that the Moon had deep recesses in which the light of the Sun did not reach and that the spots are nothing but the shadows of rivers or deep chasms.
It had been suggested already in Antiquity that the Moon was a perfect mirror and that its markings were reflections of earthly features, but this explanation was easily dismissed because the face of the Moon never changes as it moves about the Earth.

 Phases of the Moon: Zoom Astronomy
The shape varies from a full moon (when the Earth is between the sun and the moon) to a new moon (when the moon is between the sun and the Earth).
For example, the "Harvest moon" is the full moon that appears nearest to the Autumnal Equinox, occurring in late September or early October.
The new moon is the phase of the moon when the moon is not visible from Earth, because the side of the moon that is facing us is not being lit by the sun.

 Tour the Solar System and Beyond - Our Moon
Earth's only natural satellite, the Moon is unusually large in relation to its planet, having a diameter roughly 1/4 that of Earth's.
Photo: This photograph of the Moon was taken in December 1972 by the Apollo 17 mission, shortly after the spacecraft left the Moon to return to Earth.
The Moon has not undergone the continual mountain-building and volcanic activity that characterize Earth; it is a fossil planet on which the earliest stages of geologic evolution are preserved.
