Is the new moon visible from Earth? I understand the new moon phase is when the Moon is between the Earth and the Sun. Given this alignment, and considering factors like the moon’s luminosity (or lack thereof at this phase), atmospheric conditions, and potential obstructions, can we ever directly observe the new moon from Earth with the naked eye or even with optical aids? Or is its non-visibility a fundamental aspect of this lunar phase due to its positioning relative to the sun and Earth? Furthermore, if it’s technically possible under ideal circumstances, what would those circumstances be, and what would the new moon look like?

Answer

No, the new moon is not visible from Earth.

During the new moon phase, the moon is between the Earth and the Sun. The side of the moon facing Earth is not illuminated by the Sun, making it appear dark in our sky. The moon is still present in the sky, but it’s essentially invisible to the naked eye.

The new moon marks the beginning of the lunar cycle. The phases of the moon are determined by the relative positions of the Earth, moon, and sun. Because the new moon’s appearance relies on the lunar position relative to the Earth and the sun, it remains unobservable without specialized equipment.
