Why is it the sun and moon can be seen at the same time on certain days?

Very cool question.\n\nThe moon circles the earth about once a month.\n\nSo roughly every two weeks the moon is somewhere in the sky on the lighted side of the earth -- the side facing the sun.\n\nNow depending where you are standing on the earth, when the moon is in the daylight sky, you may be able to see it. \n\nIt depends on your local geography, for instance if you live in a deep valley, your view of the sky is smaller and you are less likely to see the moon and the sun at the same time.\n\nIt also depends on how close to the sun the moon appears in the sky and on the time of day.\n\nYou can use the automatic sky chart in the links below and see when the moon and sun are in the sky together.\n\nIn some cases even if the sky is too bright to see the moon, you can use a telescope or binoculars to see it. Be VERY careful not to aim at the sun, or you could seriously damage your vision.\n\nHappy moon watching!

Wow, there seem to be a lot of very stupid people answering this question.\n\nI'm assuming that you are looking for a word for when the moon and the sun are both above the horizon at any given location.  As far as I'm aware there is no specific word for this situation.\n\n"Twilight" specifies the time of day shortly after the sun has set or shortly before it is going to rise, if I remember correctly.  It has nothing to do with the moon.  And, although solar and lunar eclipses do occur when both the sun and the moon are above the horizon, they do not by any means describe all occurrences of both the sun and the moon being in the sky.

Because the moon reflects light from the sun.

As the Moon moves along its orbit around the Earth its hemisphere toward the sun is fully illuminated.\n\nBut from the Earth we see only the hemisphere that is turned toward us.\n\nThat is, we are not seeing that hemisphere which is fully illuminated by the Sun.\n\nThat is why we see different shapes which are called phases of the moon.\n\nIn new moon day, the moon is in between Sun and Earth, and the moon’s non illuminated hemisphere is toward Earth and in the back ground of Sun’s bright light, the moon is invisible.\n\nWhen Moon is at 90 degree from the Sun, half of the illuminated hemisphere of Moon is visible from Earth. \n \nWhen Moon is at 180 degree from the Sun, full of the illuminated hemisphere of Moon is visible from Earth. We call it as Full Moon.

The moon's light is actually just a reflection.  The surface of the moon reflects the suns light.  That is why you can have half moons, quarter moons, etc.  The moon itself doesn't produce any light.

"The Moon also turns around, but its "day" is a whole month long.  Because it takes as long for the Moon to orbit the Earth as it does for the Moon to rotate once, the same face of the Moon is always pointed at the Earth.  Humans had not seen the "far side of the Moon" until we were able to send spacecraft behind it.  Remember, though, that the FAR side of the Moon is not always the DARK side of the Moon"

It is the shadow of the Earth or rather, the part you see is the part that is not in the shadow of the Earth.\n\nThe shape the moon appears depends on its position relative to the Earth and the Sun. Depending on the timing, the shadow the Earth casts on the moon will change.\n\nSince the orbits of the moon and earth are constant, astronomers thousands of years ago have been able to predict the shape of the moon depending on the date.

No.  The angle between the sun and the moon as viewed from the earth is 180 degrees for the full moon pahse.  This means that the full moon and the sun are always on opposite sides of the earth.\n\nSince the moon is not always "in plane" with the sun, and your horizon is not perfect, it may be possible on occasion, depending on the geography of the horizon, and one's latitute to see the full moon rising as the sun is setting, or to see the full moon setting as the sun is rising.

The moon is only visible because the Sun light reflects off of it. Even if the Sun is in the sky at the  same time, we will see it. The Moon circles the Earth every 28 days. While the Earth rotates once every 24 hours. The result is that the Moon seems to change position in the sky by 1/28 of a full rotation every day. During that cycle, the Sun and Moon will be in the daytime sky at least half the time. Sometimes we don't notice the Moon because it is only a small wedge or the clouds hide it. \nBy the way, Venus is also visible during daylight hours during some of it's rotation,  but it is a very tiny  pinpoint of light and is very hard to locate even if it is bright.

The phases of the moon are caused by the relative positions of the earth, sun, and moon. The moon goes around the earth, on average, in 27 days 7 hours 43 minutes. \n\nThe sun always illuminates the half of the moon facing the sun (except during lunar eclipses, when the moon passes thru the earth's shadow). When the sun and moon are on opposite sides of the earth, the moon appears "full" to us, a bright, round disk. When the moon is between the earth and the sun, it appears dark, a "new" moon. In between, the moon's illuminated surface appears to grow (wax) to full, then decreases (wanes) to the next new moon. \n\nThe edge of the shadow (the terminator) is always curved, being an oblique view of a circle, giving the moon its familiar crescent shape. 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. It is fun to watch for paintings and pictures which show an "impossible moon" with the horns pointed downwards.

Its still a little bit dark and the light from earth when reflected back to the moon enables u 2 see the dark side of the moon but this will only happen when there is not enough light to block your view.

Acutally, the moon's phase isn't tilted, you're tilted.  If you saw the moon early this morning (1/26/06), it was a sliver over in the eastern sky. The bright portion looked like it had rotated counterclockwise. However, it's you, due to the rotation of the earth, that are tilted away from the axis of the moon. If you look at the moon closer to noon, the lighted portion will not appear to be tilted.

It's because your mind sees the moon in proportion to landscape features when it is low.  It's kind of an optical illusion - it's not really bigger but your mind interprets it as bigger.

because the earths atmosphere acts like a lens, so the lower the sun or moon to the horizon then the larger they appear :)

It looks like that because of the refraction of light through moisture in the atmosphere. What you are seeing is really just water in our atmosphere difusing the sunlight reflected by the moon.

I think it would because while the sun and the moon both shine, the moon is not boastful and sometimes hides away only showing it's light some of the time and, even then, only softly. Doesn't that seem beautiful to you?

between 10am -2pm the sun is high in the sky. with a high hummity it is posible to see a rainbow all the way  around the sun
