Why can't we see the Moon just before an eclipse?

When you see the moon at night, sunlight is projecting around the earth into space. Though this can cast a shadow of the earth (just as you see the sunlight wrapping around and past the moon), some light is caught by the moon and bounced back towards the earth. This gives the moon that nice glow even though it's a big rock.
During an eclipse, the moon is at a rare angle and it's zooming through the sky past the sun. In daylight, you typically won't see the moon at all. The moment it begins to eclipse the source of light, you see the reverse side of the moon. You cannot see this reverse side always because there is no light reflecting off of it. If there was, we would have two suns.

>the moon is zooming through the sky
this is why you can sometimes see the moon early in the morning and sometimes well after the sun has risen.
