Final Post (Reflection)
The Observable Universe (Thus Far) I learned quite a bit this semester and it definitely changes the way in which I look at the universe. Coming into the course I could name the planets of our Solar System and that is about it, so I basically had no previous astronomical knowledge.

Being in another star system, these worlds are very hard to observe since they are so far away and the light they produce pales in comparison to that of the stars they orbit.
