What phenomenon happens when the Earth's shadow blocks our view of the Moon?

The phenomenon that occurs when the Earth's shadow blocks our view of the Moon is known as a lunar eclipse. During a lunar eclipse, the Earth is positioned between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. This can happen only when the Moon is in its full phase, allowing us to see the shadow cast by our planet.

In a lunar eclipse, the Moon may appear to take on a reddish color due to Rayleigh scattering of sunlight through the Earth's atmosphere, which is a beautiful and striking visual effect. This event is distinct from a solar eclipse, where the Moon blocks the view of the Sun from the Earth. The other options, such as a full moon event and a new moon event, refer to lunar phases rather than eclipses, thus they do not involve the shadowing phenomenon that characterizes a lunar eclipse.
