SOLAR ECLIPSE When the sun, the moon and the earth come in a straight line, with moon in the middle, the shadow of moon may fall on some portions of the earth. Then a solar eclipse can be seen from these areas on the earth. If the umbra of the shadow falls on the earth the sun will be blocked totally at these places and total solar eclipse can be seen from these areas. In the penumbra region the sun will be partially blocked by the moon & a partial solar eclipse can be seen. Solar eclipse will always take place on a new moon day. The umbra and the penumbra are clearly visible from the earth. Never watch the eclipse with naked eyes as it can damage the eye permanently.

LUNAR ECLIPSE In a lunar eclipse, the shadow of the earth falls on the moon. When the sun, the earth & the moon come in a straight line, with the earth in the middle, the shadow of the earth can fall on the moon as moon moves around the earth; it passes through different areas of the shadow.

When it is in position A in the umbra of the shadow, it is totally covered by the shadows, & we observe a total lunar eclipse. If the moon is partially in the umbra & partially in the penumbra position B a partial lunar eclipse be seen. Once it comes in the penumbra position C these is no eclipse, but the moon appears dull as it does not receive light of sun. As it moves outside the penumbra, it shines brightly again.
