Ik ben Luna
Ik ben een vrouw en woon in Amsterdam (The Netherlands) en mijn beroep is Astrologe.
Ik ben geboren op 09/09/1969 en ben nu dus 51 jaar jong.
Mijn hobby's zijn: Nieuwe tijds leer.
Er is meer tussen hemel en aarde,zo voelbaar,denk aan de wind die je zachtjes voelt over huid..
The phases of the moon are caused by the relative positions of the earth, sun, and moon. The moon goes around the earth in 27.3 days, or 27 days 7 hours 43 minutes, on average. This measurement is relative to the stars and is called the sidereal period or orbital period. However, because of the earth's motion around the sun, a complete moon cycle (New Moon to New Moon) appears to earthbound observers to take a couple of days longer: 29.5305882 days to be exact. This number is called the synodic period or "lunation", and is relative to the sun.
The sun always illuminates the half of the moon facing the sun (except during lunar eclipses, when the moon passes through 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. The edge of the shadow (the terminator) is always curved, being an oblique view of a circle, giving the moon its familiar crescent shape.

Other Lunar Phases Information (all links open in the same new window)
USNO moon phase data - U.S. Naval Observatory Astronomical Applications Department website, a great all-around online tool for "raw" data and information about the sun, moon, and stars
moon pictures - very interesting lunar images! This NASA page has over 130 pictures (thumbnails) of the moon. Click on a thumbnail to for more info. Close-ups of the surface of the moon, distance views, astronauts, moon landings, more.
Lunar Eclipse Information
Mr. Eclipse - breathtaking eclipse photos, both lunar and solar, probably the best eclipse photography site anywhere
K-12 lunar phases activity from NASA - rather than use chalkboard diagrams to illustrate the phases, this activity uses actual objects (pencil, styrofoam ball) to help students grasp the concepts; Newton's Apple has a similar but more detailed moon phase lesson plan for elementary-age students
phases of the moon online movie - this is a short movie taught by a professional astronomer and a Newton's Apple scientist in an interesting, conversational manner, using large 3-D moon and earth spheres and simulated sunlight to demonstrate how the moon phases work
Earth-Moon-Sun system video diagrams - from NOAO (National Optical Astronomy Observatory), these QuickTime online video clips and animations are an excellent way to illustrate the moon's phases
There are many theories and thoughts about the effects of the moon on people, animals, and the natural world. Here are a few interesting links:
moon and the tides - this is a concise page on how the moon affects the tides by its phase (full moon, new moon, etc) and its position (perigee, apogee)
