Introduction You are an astronomer who has just made this image. As you study this image, what questions do you ask? Elicit answers from your audience. Then click on the slide numerous times. Each time a new question will appear.

Introduction What are these “fuzzy” objects? What are they made of? How were they formed? What are they made of? How old are they? Are they moving? How far away are they? Are they part of a system?
