The phase of the Moon when it is not visible from Earth is called the New Moon. During this phase, the side of the Moon facing Earth is in darkness, making it invisible to the naked eye. Interestingly, this is the phase that marks the beginning of the lunar cycle, which lasts about 29.5 days.

Understanding the Phases of the Moon
The Moon goes through various phases as it orbits the Earth, and these phases depend on the relative positions of the Earth, Moon, and Sun. One of these phases is particularly significant.
What is the New Moon?
- The New Moon phase occurs when the Moon is positioned between the Earth and the Sun.
- In this position, the side of the Moon that is illuminated by the Sun faces away from the Earth.
- As a result, the Moon is essentially invisible to observers on Earth.
Characteristics of the New Moon Phase
- During the New Moon, no part of the Moon's surface is lit up from our perspective.
- This is the beginning of the lunar cycle, marking the transition into the Waxing Crescent phase as the Moon starts to become visible again.
Other Moon Phases for Comparison
- Full Moon: The Moon is fully illuminated and appears as a complete circle.
- Gibbous Moon: More than half of the Moon is illuminated but not entirely.
- Crescent Moon: A small, illuminated portion of the Moon is visible, shaped like a "C."
Conclusion
Thus, when the Moon is not visible at all from Earth, it is in the New Moon phase. Recognizing these phases helps us understand the cyclical nature of lunar visibility.
