"Why is the moon doing that?" Sonic stared up at the half destroyed moon in the sky.

"It's always been like that since Eggman shot his laser beam, remember? That was when we met Shadow." Tails looked up but saw nothing worth mentioning.

"No, not the moon. That thing. Over there, can you see it?" There was a bit of light coming from what was probably a star, but most of it was covered up into a crescent shape.

"Oh, that's like, a star that's in the penumbra region."

"What?"

"You know, like the region where only a portion of the light source is obscured by the occluding body."

"Tails what the fuck are you talking about."

This is the weirdest prompt I have seen for a 30 day challenge thing. I just used it to make a shitty meme.
