lunar eclipse which is the moon blocking the sun
Full Moon
The phase in which the moon is not visible from earth is called the "new" moon. It happens when the moon is aligned between the sun and the earth (every 28 days), which causes the side of the moon that we usually see to be in shadow.
In the new Moon phase.

The Moon's phase when it's between the Earth and the sun is called a New Moon. It's in this position where at times there is a Solar Eclipse of the Sun. Please refer to the link I have attached.
The phase of the moon depends on its position relative to the Earth and the Sun. As the moon orbits the Earth, its position changes and different amounts of sunlight reflect off its surface, creating the different phases we see from Earth.
The phases of the moon are dependant on the relative positions of the sun, moon and earth. It's the angle between the view-lines to the sun and the moon, with you at the vertex of the angle. The phase of the moon you see depends on how much of the sunlit side of the moon faces earth.
All phases of the moon can be viewed from the earth. The moon is easier to see on a clear night, though the moon can also be seen during the day, depending on its orbit, and how bright the sunlight is.
In about 28 days, you would see a new moon phase after observing a waning crescent phase. The new moon occurs when the moon is positioned between the Earth and the Sun, with the side of the moon lit that faces away from Earth.
Ariel is the moon of a superior planet (Uranus), so it's never between the Earth and the Sun. If we see it at all, we see it as a full moon.
It would be the opposite. If we went to the moon when it was full, we would look back at an earth in shadow (a `new earth`) If we went to the moon when it was new, then it would be between us and the sun, so we would look back at a full earth. For a waxing gibbous from earth, the earth would be a waning crescent from the moon.
