Lunar Phases

Lunar phases are the different appearances of the moon over the course of a lunar month, and are caused by the moon orbiting the Earth and the sun hitting the moon at different angles. The different lunar phases have names; the major lunar phases in the lunar cycle are the New Moon, First Quarter, Full Moon and Third Quarter phases.

Can mood swings be connected to the moon phases?

Moon Phases and People

There is no real scientific evidence for this. The only thing that has a real connection to the moon's phases is to the cycles of the tides.

People will quote anecdotal 'evidence' to try to show connections.

Think of the wolf howling at the moon.

Certain plant species doing abnormal things while it's full or new.

Think of the saying, "Where did all these crazy people come from? It must be a full moon!"

Sometimes people come up with studies which seem to imply connections, but they haven't been able to stand up to rigorous analysis. If you think about it, before widespread street lighting, strong moonlight would enable all sorts of activities that can't happen at the dark of the moon, and people extrapolated from there. The confusion with a woman's menstrual cycle (which certainly can cause mood swings!) is a result of the coincidence of the lengths of the cycles.

How do you change the side indicator on a 2002 Vectra new shape?

Think these are the same as on the astra.You need to be a bit gentle to avoid breaking the clips.Push the whole lamp(try towards the rear first)until the small "barb"clip clears the slot and allows the lamp to swing out at one end.Then the lamp will come free.Just pull out the bulbholder and replace the bulb.Its a 501 capless type.Then simply clip the lamp back in,large clip first.

Why does the moon have phases?

ANS:The phases of the Moon are the apparent shape of the Moon as seen from Earth. From the Earth only one side of the Moon can be seen. So although exactly half of the Moon is always illuminated (toward the Sun), what we see is almost always some of the lighted part and some of the unlighted part, as the Moon moves around the Earth in its orbit. At full moons, the face toward Earth is all lighted, and at new moons, the face toward Earth is all unlighted.

The following answer provides a more detailed description of how that illumination occurs.

ANS: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.

The 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 consequently rises shortly after sunset). At last quarter, it is 90 degrees west of the Sun.

The "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.

The 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 and 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.

The 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 (west) 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.

* ("left hand" and "right hand" above refer to the Northern Hemisphere, as seen from a north-south oriented observer)
The moon's phases, contrary to a widely-held belief, have nothing to do with earth's shadow. It is only during a lunar eclipse that earth casts a shadow on the moon. The rest of the time, the shadow you see on the moon is the moon's own shadow...the hemisphere of the moon which is turned away from the sun.

The moon is a sphere, like a basketball. Only one half of the moon or ball can be sunlit at any moment. The other half is dark because the sun is below the horizon for that hemisphere of the moon or ball.

Now we know that only one half of the moon is lit at any moment. But why does it look like the moon changes shape? Well, you should also know that the line that divides the lit from unlit hemispheres (day from night) is called the "terminator". The moon is in motion around earth, so it is slowly but constantly changing its location in the sky relative to the sun. This motion causes us to view the terminator from different locations, causing the moon to look like a crescent, or a bloated egg (gibbous), etc.

Take a ball and color half of it black. Leave the other half alone. Now slowly spin the ball with your fingers and watch how the line between black and white causes the ball to appear to change shape. This is exactly why the moon appears to change.

What is the difference between a gibbous moon and a crescent moon?

Crescent is half way between half moon and new moon. Gibbous is half way between the full moon and half moon.

How much heat comes from a full moon?

there is no heat comes from the moon, moon does not posses a heat energy, this is true because plants do not continue with the process of photosynthesis during the night.

Why can't you see a new moon?

During a new moon, the side of the moon that is illuminated by sunlight is facing away from Earth so that the dark side of the moon is facing Earth.

However, during a total solar eclipse (and with protective gear for your eyes) you can see the moon at the time of new moon. You will see the night time face of the moon without any detail at all.

When is the best time to observe the features on the moon?

Do you mean besides at night? The best observation time for any celestial body is when it is as close as possible to straight overhead. This is because there is less atmospheric distortion. When viewing straight up, you are looking through 5 or 10 miles of the thickest air. When looking at something on the horizion, you are looking through 100 miles of air, maybe more. If you are refering to the phases of the moon, you will see craters in the sharpest detail when they are right on the edge between the light and dark part of the moon. A full moon is interesting but does not show the detail of the craters due to a high glare factor. As the moon is going from new to full, you can go out ever night at about the same time and see totally different features.

Why can't I see the Moon from New Zealand tonight?

The sky may be cloudy or overcast tonight in the place where you live.

Alternatively, it may be a date when the moon is only visible during the daytime.

There are at least a couple of those in every month.

What comes after the waning gibbous moon?

After the roughly-7-days of Waning Gibbous Moon ends, the
roughly-7-days of Waning Crescent Moon begins. The exact
moment between them is the moment of Third Quarter Moon.


In the lunar cycle, the "third-quarter Moon" follows the "waning gibbous" phase.

Why do moon phases occur?

The moon reflects the light of the sun.
As the moon revolves around the earth its relative position between the earth and the sun changes, so light is reflected from different portions of the moon. This is what causes the phases.
