Yes the moon in the sky is for all to see. It is visible for all to see at night.
Half of the moon is always lit up by the sun at any given time, and the moon orbits the Earth so us observers on Earth will see different amounts of the moon lit up. These different "shapes" we see are called the phases of the moon.
New Moon
same one
It does not. Residents of any country in the world can see the Moon. All you have to do is look up.
Full moon
New Moon when the moon is the middle one. Full Moon when the earth is the middle one.
You can see a full moon any time of the year. (But not every day of course)
From the Moon all you can see is planet Earth, the Moon is too far away to see any detail such as a monument on Earth with the naked eye.
It generally rises in the east and sets in the west. So you can say you can see it in the eastern AND western sky
You can see one side of the moon, but not the whole, entire thing.
There is no moon on Earth, but there is one orbiting it; we call it the moon.
No, Buzz Aldrin did not see any aliens on the Moon. There is no credible evidence to suggest that aliens have ever been observed on the Moon or encountered by astronauts during space missions.
