Does a planetary nebula have anything to do with planets? Explain.
 
  What will be an ideal response?

Question 2

A historical science: Scientists in many fields can test their hypotheses by proposing and carrying out experiments in which they can change variables in a controlled fashion.
 
  Astronomers, however, cannot adjust the properties of the objects they study. In what sense, then, can astronomers still conduct experiments?

Answer to Question 1

While these nebulae expelled by highly evolved red giants might look like greenish disks in some cases, they have nothing to do with planets.

Answer to Question 2

Astronomers can see how well their ideas match existing data, and can make predictions for the outcome of future observations.
