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.


New Moon
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.

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.

New Moons 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.

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

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) ...

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.

NEW MOON
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.

New Moons
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 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.

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.

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.
3.

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.
Eclipse Year
The 346.

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.

The period between successive New Moons.

For a few days before and after the new moon we can see a small part of the lighted half, which appears as a crescent with the horns, or cusps, pointing away from the sun.

At the time of the new moon, the moon rises at about the same time the sun rises, and it sets at about the same time the sun sets.

Initial observations suggest the new moons have circular orbits around Pluto in the same plane as Charon.

Pluto may not be getting any closer, but it's certainly getting a lot more interesting after scientists confirmed the discovery of two new moons last week.

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.

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.

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.

On August 28 1789, he erected his renowned 40ft (focal length), 48 in aperture, telescope, discovering a new moon of Saturn on the very first night's observation, and a second moon within the first month of observation.

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.

lunation: the time interval between successive New Moons. The mean interval is 29 days 12 hours 44 minutes 3 seconds (the synodic month) but, because of the perturbing action of the sun, ...

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.

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.

Because the Earth is moving around the Sun, while the Moon orbits the Earth, there is a different period for Moon phases (such as new moon to new moon)-it takes the Moon 29.5 days to complete a lunar phase cycle (a "synodic" month).

We call this New Moon, the beginning of a new cycle of lunar phases. When the Earth is between the Sun and the Moon (5), the near side is the light side. We call this Full Moon, even though we only see half the Moon.

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.

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.
