Question

what are lunar eclipse explain

Answer 1

These eclipses are actually remarkably simple considering how interesting and dynamic they can be. Basically, the Earth's shadow blocks most of the sunlight from directly illuminating all -- or a portion -- of the moon's surface.

Earth generates two cone-shaped shadows: The umbra is the dark, center shadow, and the outer, more diffused one is known as the penumbra. The penumbra encases the umbra. Both these cones are cast out from behind the sunlit side of the planet. Consequently, lunar eclipses only occur during the full moon phase (when the moon and the sun are on opposite sides of the Earth). Solar eclipses are possible only during the new moon phase (when the moon plays "monkey in the middle" between the sun and Earth).
