Okay, Ashley was starting to get worried again. Why was it always 'miss'?? But just like last time, he didn't say anything, figuring it would be best to let it go instead of making a big deal out of it. Instead, he got ready to take notes, giving the professor his full attention.
Raising his hand as soon as he thought about the question for a moment, he volunteered, "Astronomy is study of the stars and planets and space and... all the stuff in it."
That answer sort of got away from him, because he kept thinking of stuff while he was talking, so he just ended it there, quieting down in a slightly uncomfortable way.
