Lunar eclipses are special events that only occur when certain conditions are met. First of all, Imust be in "full phase". Secondly, I have to be perfectly in a straight line with the Sun and the Earth. If both of these are met, then the Earth's shadow can block the Sun's light from hitting me.
There are three types of my eclipses. Which one we will see depends on the alignment of the three celestial objects. But first, you need to know that the Earth's shadow is broken up into two parts. The umbra is the darker part of the shadow, where no part of the Sun can been seen. The penumbra is lighter than the umbra, because part of the Sun can be seen.
So, when part of mepasses through the umbra, this is called a partial eclipse. When all of me passes through the umbra, this is called a total eclipse. Finally, when I only passes through the penumbra, this is called a penumbral eclipse.
Now that you know all about eclipses, you can step outside and enjoy the show! It is my time to shine! Well, maybe not so much 'shine'... but there are always s many of you looking up at me and it makes me feel special!
Remember that my eclipses are not dangerous to the human eye, so you don't need protection to watch. Just find a nice, cozy spot and enjoy!
