New Moon from a new moon
When I get too frustrated with things, when I'm annoyed at people, when the dickishness of the commentariat gets too overwhelming, I'll just click the bookmark I made that goes to this picture:
Sigh. Much better.
The Moon does not emit its own light, shining instead by reflecting sunlight. Depending on the relative positions of the Earth, Sun and Moon, varying amounts of the lunar surface appear to be illuminated.
New moons occur on
where n is an integer. The number is defined such that lunation n = 1 corresponds to the new moon that occurred in 1923.
Uranus' New Moons
Several tiny moons have been discovered recently, most from ground based imagery! With these discoveries, Uranus joins the jovian planets in having a number of small moons in irregular orbits. Here is more up to date data.
Caliban and Sycorax ...
But you've put your finger on a key factor in seeing the crescent as soon as possible after new Moon (see the question before this one). Another requirement is for the Moon to be near perigee (closest to Earth), when it will make the quickest possible getaway from the Sun's vicinity.
New Moon - when the moon's disk is dark (and invisible to us) because the moon is between the sun and the Earth
Quarter Moon - (also called half moon) when we can see one half of the moon's disk (this is one-quarter of the entire moon's surface) ...

22 moons in 2002. Uranus has more than 20 satellites.
The Moon when it lies in the same direction as the Sun and the beginning of a cycle of lunar phases. The new Moon rises and sets with the Sun. The Moon is between Earth and the Sun at new Moon.
The phase of the Moon when the dark hemisphere of the Moon faces the Earth.
Newton's laws of gravity
See law of universal gravitation.
The lunar phase which occurs when the Moon and Sun are in the same location in the sky. The moon is, therefore, not visible as the far side of the Moon is illuminated.
The New Moon occurs when the Moon is directly on the Sun side of the Earth, or to put that another way, the Moon is "new" when it is between the Earth and the Sun.
The New Moon rises and sets along with the Sun at about the same time.

New Moon: lighted side of the Moon faces away from the Earth.
Waxing Crescent: a small part of the Moon appears lighted and grows larger on successive days.
First Quarter: the right half of the Moon appears lighted, with the lighted part growing larger on successive days.
The new moon is the phase of the moon when the moon is not visible from Earth, because the side of the moon that is facing us is not being lit by the sun.
The following moons have just recently been discovered. We still do not have any pictures, or information about them: Caliban, Sycorax, Prospero, Setebos, Stephano, and 1986U10 ...
New Moon is considered as the beginning of the cycle, hence the term New Moon. However, because the moon is between Earth and the Sun the Sun only illuminates the face that we do not see, the ‘Far Side of the Moon'.

At new moon, the Sun and Moon are seen from the Earth against the same background stars.
New Moon is in line with the Sun, so it does everything exactly when the Sun does its stuff - rises at 6 AM, sets at 6 PM, and on the meridian at Noon.
2. Full Moon does everything at opposite times relative to the Sun - rises at 6 PM, sets at 6 AM, and is highest (on the meridian) at Midnight.
If the new Moon passes exactly between the Earth and the Sun it prevents the Sun's light from reaching a small part of the Earth's surface for a few minutes and an eclipse of the Sun occurs.
When a New Moon aligns with perigee, the next New Moon returns sooner than 29 days 12 hours and 44 minutes later, the mean period between successive New Moons.
May 4 - New Moon. The Moon will be directly between the Earth and the Sun and will not be visible from Earth. This phase occurs at 22:45 UTC.
The two new moons are between 12-16 km (8-10 miles) - about the size of San Francisco. They are so faint that even Voyager 2, which discovered 10 new moons of Uranus, was unable to detect them.

new moon The moon at conjunction, when little or none of it is visible to an observer on the earth because the illuminated side is away from him. Also called change of the moon. See phases of the moon.
In fact, the length of the "lunar month" from one new Moon to the next (or from one full Moon to the next) is 29.53 days, but the Moon's orbital period is actually 2.21 days shorter (this is discussed in the section on the calendar).
The New Moons of Neptune
The six newly-discovered moons orbit with direct motion nearly in the equatorial plane. Most are closer to Neptune than its rings. Because this lies inside the Roche limit, these moons could not have formed by accretion in their present location.
The Moon would then begin to shrink, becoming first a waning gibbous and eventually reaching third quarter. Following third quarter it becomes a waning crescent, and continues to shrink until it becomes invisible at new Moon.
The moon is said to be at first quarter when it has completed one-fourth of its cycle from new moon.
2. The stage of aggregation of a substance, for example solid, liquid, or gas.
Any new moon during this period will cause a solar eclipse. For Lunar eclipses the period is shorter only about 22 days. A full moon occurring during this time will cause a lunar eclipse.

The minimum value (for a distant new moon) is based on a similar scaling using the maximum Earth-Moon distance of 407 000 km (given in the factsheet) and by calculating the brightness of the earthshine onto such a new moon.
Initial observations suggest the new moons have circular orbits around Pluto in the same plane as Charon. The orbits of Charon and the two new moons appear to be in "resonance"; for every 12 times that Charon circles Pluto, P2 orbits three times and P1 twice. (More at hubblesite.
Surprisingly enough, while weather was really unstable earlier (during New Moon ), it got really clear for a number of nights around and after First Quarter. On one of those clear late afternoons, March 19, I have decided to try hunting down as many Messier objects as possible with my CCD camera.
New moons are continually being reported in orbit of the outer planets, but I've only listed those that have been recognized and officially named. In addition to their moons, Jupiter, Saturn, Uranus, and Neptune are all orbited by diffuse rings, though only Saturn's rings are easily observable.
Altair will be NASA's new moon lander for astronauts. The lander will play an important part in the future of human space exploration. It is being built as a part of NASA's new human exploration program, Constellation.
A solar eclipse occurs when a new moon passes between the Sun and Earth, and are usually defined as either total, partial, or annular. These natural phenomenona take place on average twice each year, but with the rarer total solar eclipses happening about once every 1.5 years.
Why don't we have a solar eclipse during every new Moon? This is because the Moon's orbit around the Earth is at an angle to the ecliptic. The new Moon usually passes above or below the Sun as seen from the Earth and thus there is no eclipse.
Of course, this can also only occur when there would normally have been a new moon. It is only when these "eclipse seasons" match up with the date of a new moon that solar eclipses occur. Since this will occur at 1:20 EST, the Sun will be about 20 degrees west of south during the eclipse.
In this movie, the bright object below S/2003 U 2 is Belinda, whose orbital path is just 200 to 450 miles (300 to 700 km) from the new moon.
June 27 - 4:08 A.M. EDT: New Moon. 5 A.M. EDT: The June Bootid meteor shower is at peak activity.
June 28 - 11 P.M. EDT: The Moon is 5° south of Jupiter.
June 30 - 3:10 P.M. EDT: The Moon is at apogee, the point in its orbit when it is farthest from Earth.
solar eclipse -- the passage of the new Moon directly between the Sun and the Earth when the Moon's shadow is cast upon the Earth. The Sun appears in the sky either partially or totally covered by the Moon.
New Moon, First Quarter, Full Moon, and Last Quarter are defined as the times at which the excess of the apparent celestial longitude (see Longitude, Celestial) of the Moon over that of the Sun is 0°, 90°,180°, and 270°, respectively. [S92]
Cyclically recurring apparent forms of the Moon. New Moon, First Quarter, Full Moon, and Last Quarter are defined as the times at which the excess of the apparent celestial longitude (see Longitude, Celestial) of the Moon over that of the Sun is 0°, 90°,180°, and 270°, respectively.
Month, Synodic. The interval between two successive New Moon's (a lunation), equal to 29.53 days.
Month, Tropical. The time taken for the Moon to return to the same celestial longitude (7 seconds shorter than the sidereal month).
Is the season when the Sun is close enough to a node for an eclipse to occur, An eclipse season is 32 days. Any new moon during this period will cause a solar eclipse. For Lunar eclipses the period is shorter only about 22 days. A full moon occurring during this time will cause a lunar eclipse.

His theory gave reasonably satisfactory results for the motion at Full and New Moon. Hipparchus was dissatisfied however, for, as he appreciated, the errors at quadrature (when the Moon stands at first and last quarters) were too great.
