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.

But you've put your finger on a key factor in seeing the crescent as soon as possible after (see the question before this one).

Is there a way to find out if a new moon has actually been sighted vs. just calculated or predicted.
There is an project called the Islamic Crescents' Observation Project which seems to do just what you're asking.
Still Curious?

s of Pluto
Using NASA's Hubble Space Telescope to probe the ninth planet in our solar system, astronomers have discovered that Pluto may have not one, but three moons.

New Moon
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.

new moon
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 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 rises and sets along with the Sun at about the same time.

cannot actually be seen because the shining side of the moon is facing away from Earth, and the dark side is facing Earth. The is close to the sun in the sky as we look at it from Earth, so it rises and sets at the same time.

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'.

A new moonlet and strange vertical structures are among the treasure trove of goodies revealed by the Cassini spacecraft as Saturn nears equinox.

At , 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.

If the 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 - . 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.

3 Nov. The Moon eclipses the Sun for observers across the northern Atlantic and the equatorial regions of Africa.

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 s of Neptune
The six newly-discovered moons orbit with direct motion nearly in the equatorial plane. Most are closer to Neptune than its rings.

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 .
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 ) 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 .
