Moonless
Moonless refers to a condition or time period in which the moon is not visible in the night sky. This can be due to the moon being in its new moon phase, obscured by clouds, or below the horizon. During these moonless nights, the sky appears darker and celestial objects such as stars, planets, and galaxies may appear more vivid and prominent. Moonless nights are often favored by astronomers and stargazers for observing fainter objects in the night sky.
