Astronomy assignment for 4-13-2017

Please read sections 28.1 through 28.2

Answer these questions and turn in on paper, or share it with me in a google doc

  1. How are distant (young) galaxies different from the galaxies that we see in the universe today?
  2. What is the evidence that star formation began when the universe was only a few hundred million years old?
  3. Describe the evolution of an elliptical galaxy. How does the evolution of a spiral galaxy differ from that of an elliptical?
  4. Explain what we mean when we call the universe homogeneous and isotropic. Would you say that the distribution of elephants on Earth is homogeneous and isotropic? Why?

If you finish early, please continue working on your website and/or book report.
