What are the moons shadows and the two parts?

The moon's shadow during an eclipse consists of two main parts: the umbra and the penumbra. The umbra is the darker, central part of the shadow where the light from the Sun is completely blocked, resulting in a total eclipse. The penumbra, on the other hand, is the lighter, outer part of the shadow where the light is partially obscured, leading to a partial eclipse. Together, these two areas define how the eclipse is experienced from different locations on Earth.
