Things you might not know about if you were homeschooled in the US.
The shadow of an eclipse is broken into three parts: the umbra, penumbra, and antumbra.
The umbra is the darkest part of the shadow where the Moon completely covers the Sun. The antumbra is the area surrounding the umbra, where the Moon is in front of the Sun, but it isn’t covering the Sun entirely, so the shadow is not as dark. The penumbra is the outer area of the shadow where the Moon only covers part of the Sun.
