Can someone tell me the exact difference between a lunar eclipse & a normal "no moon" day?

Question

Well.....I tried to figure it out & found it a bit confusing.....

I hope u can make me understand it.....

Answer 1

A normal "no moon" day would be around the time of New Moon, when the moon is near to the sun and sets more or less at sunset and doesn't rise until about sunrise. The moon would not therefore be visible at any time during the night. When a lunar eclipse takes place, the Full Moon passes into the earth's shadow and usually becomes dim and red in colour but is normally still visible. On occasions, however, the earth's shadow can be particularly dark and the moon becomes quite difficult to see at all during an eclipse, so pehaps this could be regarded as a "temporary" no moon day, but only for an hour or so.

Answer 2

First, from the point of view of a typical Earth observer...

In a "no moon" day, the Earth observer will not see the moon for the entirety of the night.

During a lunar eclipse, on the other hand, the moon is full (lunar eclipses can occur only during a full moon), and then the darkness eats it up until it disappears. After some time, the moon re-appears and goes back to being a full moon. Usually, the moon turned a reddish hue before and after a lunar eclipse.

Now, astronomically... A "no moon" day occurs when the moon passes somewhere between the Earth and the sun. The moon is not seen because its surface is unable to reflect any light from the Sun onto the earth.

On a lunar eclipse, on the other hand, the Earth is between the Sun and the moon, and the orientation is such that the Earth is able to cast a shadow over the moon, hiding it temporarily.
