  Very Important: Before you do anything, decide on a title for your discussion, and write “TOPIC: (fill in your title here)” on the first line of the page.
  Next, leave a blank line, and then start writing your post about the new topic

Your discussion choices can be related to anything focused on Astronomy and/or planetary exploration. Here are some examples of the most popular types of posts:
    Current events in the news that are related to astronomy and/or planetary exploration
    A documentary that you watched about astronomy or planetary exploration
    A topic that was brought up in the textbook or in lecture.
You can discuss anything you wish to discuss, so long as you choose topics that are focused on Astronomy, particularly the study of our solar system or other solar systems.
