About Shadows ?

In our solar system, the light from the sun falls on all the planets and their moons. Each of these casts its shadow in the direction opposite to the source of light - the sun. Where does this shadow fall ? Usually into space. Sometimes the shadow of one of these planets or moons falls on an other planet or moon. If we view the sun at this time from this location, the sun is partially or fully covered. This we call as an eclipse. We have many eclipses in our solar system- that of the sun, the moon and the satellites of jupitor. For example, when the moon passes in front of the sun, the shadow sometimes falls on the earth's surface. And if we view the sun from this shadowed location, the moon covers the sun's disc. This is what a solar eclipse is - and in fact it is nothing but a shadow.
