The New Moon is the first phase of the moon and marks the start of a new lunar cycle as it happens when the sun and earth are aligned in a straight line with the moon in the middle.
During this time, the moon stays near the Sun, rises, and sets with it. The moon travels with the Sun during the day.
Due to the proximity of the sun, the part of the moon facing toward the Earth is shadowed. Hence, it is invisible to the naked eye.
However, it can be viewed with special telescopes.
The lunar cycle (the moon orbiting the Earth) lasts for about a month, or 29.5 days causing the New Moon once a month.
During the new moon, the satellite is lit up from behind toward the Earth and is completely invisible.
After a couple of days, a slim crescent moon can be seen. The waxing Moon phase starts after a week when the moon is 50% illuminated.

The Phases of the Moon
The phases of the Moon are determined by how much of the illuminated side of the moon is visible from the Earth.
There are four phases of the Moon:
- the new moon,
- the first quarter,
- the full moon,
- the last quarter.
Between each phase, there are intermediate phases, in which the Moon appears either crescent or gibbous and these phases last for around 7.38 days.
The crescent and gibbous phases can be waxing or waning.
When the moon is waxing it means it is getting more illuminated while waning means less illuminated.
The duration between the new moon to the full moon, or vice versa, can go from 13 days to 15 days.
The New Moon and Solar Eclipses
Solar eclipses happen around two to three times a year only during a new moon.
For a solar eclipse to happen, the Sun, Moon, and Earth have to be perfectly aligned meaning that the Moon is closest to the ecliptic plane.
During a solar eclipse, the Moon blocks the sunlight, causing the Earth to be completely shadowed during the day.
