why can we see the moon?
610797
We only see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit.

Moon light is bare electromagnetic radiation / photons, being reflected from the Sun to Earth. ... UV radiation is easy to get lost by its high frequency and energy, it bouces easily in the Moon sand, very little if much, we receive of UV from the Moon.

From Earth, through a small telescope or strong binoculars, they look like tiny starlike pinpricks of light. ... If a moon is in front of the planet, you can sometimes see the moon's shadow on Jupiter's cloudtops. Going from closest moon to Jupiter to the outermost, their order is Io, Europa, Ganymede and Callisto.

To find the distance of the Moon from the Earth, you and a friend stand 3,200 km apart and each take a picture of the Moon at exactly the same time. Then, compare your images. The Moon will be in a different spot, but the background stars will be in the same place. What your images have given you is a triangle.

Earth's Moon's rotation and orbital periods are tidally locked with each other, so no matter when the Moon is observed from Earth, the same hemisphere of the Moon is always seen.

When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse.

This ring surrounding the Moon is caused by the refraction of Moonlight (which is really reflected sunlight, of course) through ice crystals suspended in the upper atmosphere between 5-10 km in altitude. ... Generally they're seen with cirrus clouds; the thin, wispy clouds at high altitude.

Rings around the Moon are caused when moonlight passes through thin clouds of ice crystals high in Earth's atmosphere. As moonlight passes through the ice crystals, it is bent in a way similar to light passing through a lens. The shape of the ice crystals causes the moonlight to be focused into a ring.

As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5). The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days.

The near side of the Moon is the lunar hemisphere that is permanently turned towards Earth, whereas the opposite side is the far side. ... Sometimes the dark portion of the Moon is faintly visible due to earthshine, which is indirect sunlight reflected from the surface of Earth and onto the Moon.

The sun, earth, and moon are held together by gravity, and they interact in lots of ways. The moon orbits the earth because of the pull of the earth. And the earth orbits the sun because of the pull of the sun. Because of the way they move relative to each other, we see phases and eclipses.

And it's light in another sense, too: The "dark" side has few of the distinctive dark spots that mark the Earth-facing side of the moon. Those spots are called maria, from the Latin word for sea, because early astronomers mistakenly thought they were lunar seas (they're actually volcanic plains).

The Moon lacks water, an atmosphere, and tectonic activity, three forces that erode Earth's surface and erase all but the most recent impacts. ... Essentially, the Moon's surface has not been modified since early in its history, so most of its craters are still visible.

While the moon's magnetic effect is not creating a physical movement of water in our bodies (according to science), it could be bringing heightened emotions to surface. At the full moon, there is an additional brightness to the night sky. ... You may find yourself feeling anxious or emotionally upset.

Characteristics of our Moon include its size of only about 1/4 the diameter of the Earth, while its gravity affects the Earth's tides. The Moon looks bright at night because of sunlight that is reflected off its surface. It has some distinct surface features that can be seen with the naked eye.

A lunar eclipse is fine to look at but solar eclipses are only safe to look at when the sun is completely obscured by the moon. Staring at it before then, even briefly, can cause irreparable eye damage, according to scientist Bill Nye.

To the eye, the moon appears round, and it's natural to assume that it is actually spherical in shape – with every point on its surface equidistant from its center – like a big ball. Not so. The shape of the moon is that of an oblate spheroid, meaning it has the shape of a ball that is slightly flattened.
