What is the phase of the moon when solar and lunar eclipses occur?

During the solar eclipse, the sun and the moon are on the same side, so they are "new moon", that is, new moon; during the lunar eclipse, the sun and the moon are on both sides of the earth, and they are "looking", that is, full moon. Because during the full moon, the position of the moon, the earth and the sun is: Moon earth sun. When the sunlight is blocked by the earth, the moon enters the shadow of the earth (much like the shadow on the earth)
