This site is dedicated to a discussion about our Universe... what we know about it, how it is evolving, and the kinds of objects and phenomena it contains. Just as importantly, we also discuss how scientists know what we know, what mysteries remain, and how we might one day find the answers to these questions.

You will navigate around our site using a series of buttons at the bottom of each page. This is your chance to learn about the navigation buttons!

 Any time you see , you can go to a new window showing the Math and Science Education Standards for that page. When you are done viewing the standards, close that window to return to the page you were on previously.
