Since humans have walked the earth, we have stared at the changing moon with wonder. But what really causes the appearance of the moon to change so drastically ?

Astronomy compels the soul to look upwards and leads us from this world to another.

- Plato

The answer has to do with the position of not just moon but the sun and the earth as well. This is also what causes eclipses and tides.

Remember that the sun is the center of our solar system and the Earth is revolving around the sun as the year goes by and rotating on its axis.

The moon is the first milestone on the road to the stars.

The moon revolves around the earth approximately every 28 days. Its rotation is also approximately 28 days. So the same side of the moon is always facing the earth.

Aiming for the moon and missing it is better than aiming for the ditch and hitting it.

The Moon does not give off its own light but reflects light from the sun. Half of the moon that faces the earth is not always the half that is being lit by the sun.

Everyone is a moon, and has a dark side which he never shows to anyone .

There are two high tides and two low tides each day.
Tides are caused by the pull of both the sun and the moon on the Earth.
Changes in the positions of the Earth, sun, and moon affect the height of the tides throughout the month.

But why, some

say, the moon?…

And they may well

ask, why climb the highest mountain?

Caused when the earth, moon, and sun are in a straight line
The combination of the gravitational pull of the sun and moon cause the ocean of the Earth to Bulge.
Spring tides occur during new and full moons.
Spring tides have the greatest range between high and low tides. Really high, high tides and really low, low tides.
Named from an Old English term meaning to jump -- NOT FROM THE SEASON

That's our new frontier out there, and it's everybody's business to know about space.

Occur during first and third quarter moons.
Produce the least range between high and low tide.

A solar eclipse is when an object in space casts a shadow from the sun on another object in space.

A lunar eclipse occurs when the Earth blocks the sunlight from reaching the moon.

Question: Why do lunar eclipses occur only during full moons?

Answer: That is the only time that the earth comes between the moon and sun.

Question: Why don’t we have a lunar eclipse every full moon?

Answer: The tilt of the moon’s orbit is 5° different than the earth

Question: Why does the full moon appear to be red during certain times of the year?

Answer: The light from the sun gets bent as it passes through our atmosphere causing it to appear red.

Shoot for the moon. Even if you miss, you'll land among the stars.

Occurs when the moon passes between the Earth and sun, blocking the sunlight from reaching Earth.

Total solar eclipses are visible on Earth for only a few hundred miles wide. A lunar eclipse visible for at least half the earth.
