You are right.\n\nAn astronaut standing on the "earth" side of the moon during a "new moon" might see the small shadow of the earth moving across the surface of the earth -- a partial eclipse of the earth.\n\nNot total eclipse of the earth by the moon's shadow is possible because the moon is too small.\n\nThe oddball thing is that by coincidence the moon appears to be the same size in the earth's sky as the sun. about one finger tip at arms' length which is about half a degree of angle.

Full moon\n\nThe Galileo spacecraft took this composite image on 7 December 1992 on its way to explore the Jupiter system in 1995-97. The color is 'enhanced' in the sense that the CCD camera is sensitive to near infrared wavelengths of light beyond human vision.The Full Moon is the lunar phase that occurs when the Moon lies on the opposite side of Earth from the Sun. The Moon as seen from the surface of Earth is fully illuminated by the Sun at this time, presenting a "full" round disk to viewers on Earth. As always, only half the total surface of the Moon is illuminated.\n\n\n1 Eclipses \n2 Numbers and formulae \n3 Folklore \n4 Calendars \n5 Full Moon names \n6 The Blue moon \n7 See also \n8 References \n \n\n\n\nEclipses\nA Full Moon is the only time when a lunar eclipse is possible; at that time the Moon may move through the shadow cast by Earth. However, because of the tilt or inclination of the Moon's orbit around Earth relative to Earth's orbit around the Sun, the Moon usually passes to the north or south of Earth's shadow at Full Moon, so a lunar eclipse does not occur at every Full Moon.\n\nFull Moons are generally a poor time to conduct astronomical observations, since the bright reflected sunlight from the Moon overwhelms the dimmer light from stars.\n\n\nNumbers and formulae\nAlthough on average it takes only 27.322 days (sidereal month) for the Moon to complete one orbit around Earth, it requires about two more days than that to again catch up with the Sun. On average, the number of days between Full Moons is about 29.5306 days. The actual number of days may differ from the average number by more than a half day. From one Full Moon to the next, the number of days in one lunation can vary between 29.272 and 29.833 days.\n\nThe age and apparent size of the Full Moon vary in a cycle of just under 14 synodic months, which is called the Full moon cycle.\n\nThe combined date and time of Full Moon number N, using a fictitious moon that moves at a strictly mean rate is approximately:\n\nD = 20.362954 + 29.5305888531 × N + 102.19 × 10-12 × N 2 \nD is the number of days (and fractions) since 1 January 2000 00:00:00 UTC, \nN is the count of full moons starting with zero as the first (not 1 as you would have expected) as the first Moon in the year 2000. \nThe true Full Moon may differ from this by up to about 14.5 hours, due to the normal irregularity in the Moon's Keplerian orbit, and due to the periodic perturbations on that Keplerian orbit by the Sun, the equatorial bulge of Earth, and nearby planets.\n\nSee the New Moon page for a detailed explanation of the formula.\n\n\nFolklore\nFull Moons are traditionally associated with temporal insomnia, insanity (hence the terms lunacy and lunatic) and various magical phenomena such as lycanthropy.\n\nPsychologists have found that there is no strong evidence for effects on behaviour around Full Moon [1]. They find that studies are not consistent, with some showing a positive effect, while others will show a negative effect. In one instance, the December 23, 2000 issue of the British Medical Journal published two studies on dog bite admission to hospitals in England and Australia. The study of the Bradford Royal Infirmary found that dog bites were twice as common at Full Moon, while the study of public hospitals in Australia found they were less likely at Full Moon. Psychologists point out that there is a difference between correlation and causation. The mere fact that two events happen at the same time doesn't mean that there is a cause and effect relationship between the two.\n\nNeopagans hold a monthly ritual called an Esbat at each Full Moon.\n\nMany people practicing traditional Chinese religions prepare their ritual offerings to their ancestors and deities on every Full Moon and New Moon.\n\n\nCalendars\nThe Islamic calendar and the traditional Chinese calendar are both based on the phases of the Moon. Neither calendar, however, begins i

if you mean like a new moon (solar eclipse) <every new moon, and a full mooon (lunar eclipse) <every full moon:\n\nbecause the earth and moon are not on the same plane, and the moon is in a higher altitude than earth, and the moon only crosses sometimes into the earth's plane with the sun.

A solar eclipse occurs when the Moon passes in front of the Sun and obscures it totally or partially. This configuration can only occur at New Moon, when the Sun and Moon are in conjunction, as seen from the Earth.\n\nThere are four types of solar eclipses:\n\n1.A total eclipse occurs when the Sun is completely  obscured by the Moon. The intensely bright disk of the Sun is replaced by the dark outline of the Moon, and the much fainter corona is visible (see image right). During any one eclipse, a total eclipse is visible only from a fairly narrow track on the surface of the Earth. \n2.An annular eclipse occurs when the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun. Hence the Sun appears as a very bright ring surrounding the outline of the Moon. \n\n3.A hybrid eclipse is intermediate between a total and annular eclipse. At some points on the Earth it is visible as a total eclipse; whereas at others it is annular. The generic term for a total, annular or hybrid eclipse is a central eclipse. \n\n4.A partial eclipse occurs when the Sun and Moon are not exactly in line, and the Moon only partially obscures the Sun. This phenomenon can usually be seen from a large part of the Earth outside of the track of a central eclipse. However, some eclipses can only be seen as a partial eclipse, because the central line never intersects the Earth's surface.

no it's not cos of the earth's shadow on the moon. its cos of the position of the sun and the angle at which the sun's rays hit the moon. the moon moves around the earth. if it moves further from the sun, less light will be reflected and you see a half-moon or quarter-moon.\n\nas u know, the light hte moon 'projects' is actually the reflection of light. the moon isnt a source of light. \n\nwhen the sun is directly behind the moon, and it shines on the 'back' of the moon, this causes an eclipse cos ppl on earth can only see a dark circle (the moon - as it does not reflect light in this case) and a whitish circle around the moon (the sun's rays)\n\nhope this helps!! :D

A lunar eclipse is much slower than a solar eclipse when viewed from Earth. On average a lunar eclipse is visible from a point on earth for between 4 and 5 hours, a solar eclipse usually lasts 90 minutes.

First, you must picture in your mind the 3 celestial bodies: sun, earth and moon. Picture the moon circling the earth: now it is between the earth and the sun, now it is at the other side of the earth, now it comes back again between earth and sun... As you know it takes about 4 weeks for the moon to make an entire circle around the earth.\nWhat happens when the moon is between us and the sun? well, it receives light from the sun on the face that is turned that way, so  we can't see it at the moment. That's why we can't see the new moon! It's there is the sky, but not lighted in the side facing us!\nThen 2 weeks later the moon is on the opposite side. The face that is facing the sun - and reflecting all that sunlight - is also facing the earth! So we see it fully - full moon.\nBut the path of the moon is not entirely on the same plane as us and the sun, there is a slight angle!!  Only sometimes it happens that the shadow of the earth catches the moon when it's full (and when it is perfectly aligned with the earth and the sun). THAT's your eclipse!!

The next total solar eclipse will occur in August 1, 2008, going from Northern Canada over Greenland and Siberia and ending in Mongolia.  The next total lunar eclipse will be in March 3-4, 2007.

This happens every day... The sun is always visible to us on Earth.  Only durring a solar eclipse is the sun not visible to us.  And the stars are always there but you can't see them with the sun becuase the sun out shines the ohter stars.

An eclipse refers to the phenomenon of one body passing into the shadow cast by another body. In astronomy, the best-known type of eclipse occurs whenever the Sun, Earth and Moon line up exactly. If this occurrence is at the time of a Full Moon where the Moon passes through the Earth's shadow, it is called a lunar eclipse. The type and length of a lunar eclipse depends upon the Moon's location relative to its orbital node. If the lining up of the Sun, Moon and Earth occurs at New Moon, the event is usually referred to as a solar eclipse (although the term is a misnomer and can more accurately be referred to as an occultation of the Sun by the Moon).

They are not the same.  During a full solar eclipse, the moon's shadow is only a spot on earth because the moon is much smaller than the earth, you have to be inside that spot on earth to see the full solar eclipse.\n\nDuring a full lunar eclipse, the earth's shadow covers the entire moon, and you don't see the moon no matter where on earth you are.

One of the biggest misconceptions about the Moon is that its phases are caused by the Earth's shadow. The Earth's shadow causes eclipses, but it has nothing to do with phases. Rather, the phases of the Moon are produced by the alignment of the Moon and the Sun in the sky. \nThe orientation of Sun and Moon determines the phase of the Moon. At new moon, the angular distance of the sun and moon is small, less than a few degrees. At first quarter, when the moon is half full, the Moon lies 90 degrees east of the Sun. As an example, if you were to point to the setting sun with one arm and to the moon with the other, the angle between your arms would be 90 degrees. At full, the moon is 180 degrees from the sun and at last quarter, it is 90 degrees west of the sun. \n \n\nThe new moon is essentially invisible because it is between the earth and sun and therefore lost in the glare of the sun. Even on day 2 or 3 it is tough to spot the moon because it is just the tiniest sliver and still very close to the sun. The waxing crescent moon grows till it is about half full in the phase we call first quarter. From there it grows to full moon and then begins to shrink back to third quarter, waning crescent and finally back to new moon. \n\nThe first and last quarter moons mark the halfway points between the new moon and full moon. The first quarter moon is illuminated on the right hand side. The last quarter moon is illuminated on the left hand side. It seems conflicting to call a half full moon first of last quarter, but the quarter refers to the position of the moon in the sky, not it's phase. A quarter moon is one quarter of a full circle (90 degrees) away from the sun. \n\nThe lighted part of the Moon always points the way to the Sun. This means that a waxing crescent moon in the western sky at sunset has the lighted part on the right which is the direction of the Sun. The sequence of the lunar phases always proceeds with the lighted part of the Moon growing from right to left until the moon reaches full. After full moon, the light recedes from right to left until new moon. \n\nThe line boundary between dark and light on the Moon is called the terminator. It is rarely an even line because the surface of the Moon is not smooth. The terminator is closest to a straight line at first and last quarter. Librations affect exactly what portion of the face of the Moon is facing the Earth, during first and last quarter phase, the terminator's exact location may vary. This is illustrated when the terminator does not line up with the Moon's meridian at first and last quarter. In other words, you'd think that during first and last quarter when the Moon is half full, that the meridian (the imaginary line which runs from north to south on the Moon,) would be right on the terminator, but it isn't so. In fact the terminator can be almost 8 degrees off to either side of the meridian.

the light side of the moon move in front of the sun causing it to form the image you see that is know as the solar eclipse\n(since the dark side of the moon is facing you then it's clearly dark, and the sun's behind it so light shines around it)

The phases of the moon occur due to its relative position to us and the sun. The sun always shines on half of the moon (except on the rare occassion when the earth is in the way causing a lunar eclipse). If the moon is behind the earth, we see it as a full moon as we can see all of the lit side. When the moon is beside the earth, we see half the lit side and half the side in shadow, which appears to us as a half moon. When it's in front of the earth its a new moon which isn't visible as we can only see the side of the moon in shadow. In between the stages we see the crescent waxing and waning moons.

An eclipse is when one body is between the Earth and another, obscuring it from view.  There are different kinds,  A solar eclipse is when the moon blocks the sun.  A lunar eclipse is when the Earth blocks the sun's light from reaching the moon, causing our shadow to pass over it.
