The umbra, penumbra and antumbra are the names given to three distinct parts of a shadow, created by any light source after impinging on an opaque object. For a point source only the umbra is cast. These names are most often used to refer to the shadows cast by celestial bodies, though they are sometimes used to describe levels of darkness, such as in sunspots.
