What phase of the moon is a lunar eclipse?
full moon phase
Lunar eclipses occur at the full moon phase. When Earth is positioned precisely between the Moon and Sun, Earth’s shadow falls upon the surface of the Moon, dimming it and sometimes turning the lunar surface a striking red over the course of a few hours. Each lunar eclipse is visible from half of Earth.
Why is a lunar eclipse not possible at this time?
Exploratorium Senior Scientist Paul Doherty explains why not—the orbit of the moon is tilted relative to the orbit of the Earth around the sun, so the moon often passes below or above Earth. At those times, it does not cross the line between the sun and the Earth, and therefore does not create a solar eclipse.
Why don’t we see an eclipse at every new and full moon describe the conditions needed for a solar or lunar eclipse?
We don’t see an eclipse at each new moon or full moon because eclipses only occur when the moon is in perfect alignment with the earth and sun while passing through the nodes. For a solar eclipse, the moon has to lie directly between the sun and the earth so as to cast it’s shadow on the earth.
Can Moon block the Sun?
The Short Answer: Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. During a total solar eclipse, the Moon passes between Earth and the Sun. This completely blocks out the Sun’s light.
What is the darkest part of the moon?

Why there is no eclipse every month?
A lunar eclipse occurs when the Moon enters the Earth’s shadow. A solar eclipse occurs when the Moon’s shadow falls on the Earth. They do not happen every month because the Earth’s orbit around the sun is not in the same plane as the Moon’s orbit around the Earth.
