Can You See a New Moon at Night
I stumbled beyond this question, and while it is an old question and there are some halfway decent answers, I think information technology deserves a more in-depth response. I completely empathise the question, which I retrieve is am excellent question. Trying to empathise the phases of the moon is much more than hard than about retrieve.
The brusque respond of it is that you cannot encounter a new moon at night. A new moon is non in the sky at night! It rises with the sun and sets with the lord's day.
The closest you lot can become to "seeing" a new moon is a "waxing crescent" right after the sun sets, or a "waning crescent" correct earlier the sun rises.

A "waxing crescent" - virtually a new moon - is seen only very briefly afterward sunset. This is because at waxing crescent, the sun rises immediately before the moon rises, and then the sun sets immediately before the moon sets. Therefore, right afterward the sun sets, and the sunday'south glare fades in sunset, the very slim crescent (nearly a new moon) becomes visible, and so the moon soon thereafter sets...and can't be seen for the remainder of the dark. If the sunday'southward glare weren't so brilliant during the twenty-four hour period, you lot could run into the moon with this slight crescent all mean solar day long. Merely y'all tin can't. Yet, at dusk, when the sunday'south glare fades over the western horizon, the slim crescent appears! (it doesn't appear because it comes upwardly higher up the horizon, but just because the sun's brightness fades into the nighttime). Only watch the waxing crescent into dark, and yous will see it quickly set up below the western horizon, and it won't be seen once again until the following sunset.

A "waning crescent" - nigh a new moon - is seen only very briefly earlier lord's day rising. This is considering at waning crescent, the moon rises immediately before the sunday rises, and so the moon sets immediately before the sun sets. As a result, right before sunrise, in early dawn, the slim crescent moon (well-nigh a new moon) rises in the Eastward. Information technology appears as it rises in a higher place the Eastern horizon, before the sun rises. All the same, y'all can't run across it very long, either, considering and so the sun rises, and the sun'south glare is so vivid, it overwhelms the slim glimmer of the waning crescent! However, it is still at that place...and is there in the sky all solar day long! And finally, the moon sets first over the western horizon in dusk, non to be seen. And so the sun sets...to a moonless nighttime almost all night until right earlier dawn, when the waning crescent rises to be seen again.

At present and then, to more adequately address and answer your question, permit's showtime take this unproblematic demonstration of a daughter rotating effectually in circles while property a "moon" in front of her with a lamp (lord's day) in the distance:
From here: http://world wide web.jpl.nasa.gov/educational activity/index.cfm?page=123
In this sit-in (different in reality), the girl is always facing the moon equally she rotates. She will surely encounter the various "phases" of the moon in this demonstration, which is a skillful demonstration for this purpose. Nonetheless, perceiving where this demonstration fails in comparison to what really happens with the World, Moon, and Sun will assistance answer your question.
Failure #ane: When the girl is facing the lamp with the moon held out in front end of her (in Pace 1), she will "see" a "new moon". But, when she can come across a full moon, she is facing the sun...i.e. it is the day for her.
The reason the demonstration fails is that during a truthful new moon, when the moon is between the Earth and the lord's day (during the day), we can't encounter the moon because the sun is also vivid. In other words, although in the demonstration the girl can encounter her "moon"...nosotros tin can't meet ours. For her demonstration to be more authentic, her "moon" would have to be a LOT smaller and the lamp would have to be MUCH brighter. And if the lamp were much brighter...even blindingly bright, then she would not be able to see her small "moon" either.
Although, if the moon passes exactly betwixt the lord's day and the globe during the day, so we take a total solar eclipse. And during that cursory moment, the moon blocks the lord's day and shades the earth...and we can see the outline of a new moon:

Failure #2 (and the answer to your question): The sit-in fails considering the girls is always facing the moon. In reality, this is not then. The Earth rotates, of grade. So, for the sit-in to be more accurate, her caput would take to be impossibly rotating completely around 360 degrees, continuously. Furthermore, her head would be rotating almost 30 times as fast around in circles equally her body.
In other words, during the "new moon" phase (Pace ane), when her body is facing the lamp (sunday) with her arm holding the moon out in the direction of the lamp (dominicus), imagine her caput revolving around 360 degrees.
Then, while imagining her head turned around backwards (like in the Exorcism picture show), as in during the "night" for the daughter...her head would be facing the Contrary direction of the moon AND dominicus, and the "new moon" would not be visible at nighttime...anymore than the sunday. This is because she is no longer facing either i. The "new moon" would not be visible at night, because it is not in her vision of the sky during her night.
Now and so...as her head rotated around, and out of the corner of her middle (in the Eastern horizon), she would begin to see the moon and sun at the same time (i.e. during sun and moon ascension in the morning time), then they would announced together...exist in the sky together all day...and set together out of the corner of her eye, again at dusk. In the demonstration, she would be able to encounter the brawl and the lamp, but in reality, the sun is so bright that the moon can't be seen in the sky...even though the new moon is in the sky all day long.
During the waxing and waning crescents (as above), the moon sets just afterwards the sun or rises but before the lord's day (respectively). Therefore, an about new moon can exist seen briefly before the moon sets or sun rises (respectively).
Finally, understanding a full moon helps shed more light (forgive the pun), as well: Right when the sunday is setting, a full moon is rising in the Due east! The full moon is visible all night long and sets in the Due west, simply as the sun is rising in the East the next morning time.
Then, a full moon rises early in the nighttime and sets early in the morn...is visible all night long.
Contrarily, a new moon rises early on in the morn (with the sun) and sets at night (with the sun)...and is not visible at night, at all.
This website is very helpful in its descriptions, as well: http://earthsky.org/moon-phases/new-moon
But once again, the best time to virtually come across a "new moon" (besides a full solar eclipse, of course), is shortly after the new moon...at dusk during a "waxing crescent"...or shortly earlier the new moon...at dawn during a "waning crescent".
I hope this helps!
