Eclipse of the moon and solar eclipse

Lunar eclipse occurs due to the nature of the sun that falls to the moon is blocked by the Earth. Only lunar eclipse occurs when the full moon and the moon goes into the earth's shadow. When the moon does not receive sunlight so we can not see the moon. Currently this kind is called a lunar eclipse.
Because the Earth is much smaller than the sun, the earth's shadow tapered conical core. Area through which the shadow of the earth's core is very dark and is referred to as the umbra. Rather bright shadow called the penumbra. Lunar eclipse approximately 6 hours, but truly the core shadow only 1 hour 40 minutes. When the moon is in the penumbra, the moon looks vaguely. If the moon in the umbra, the moon completely invisible.
Solar eclipse can occur if the position of the sun, moon and earth are in a straight line. So that the sunlight that falls to Earth's surface is blocked by the moon. Solar eclipse occurs at noon. The total solar eclipse lasts approximately 6 minutes.
