BIGGER....No Problem
I'm Not Lost
   
         
Have you ever stood outside and looked at the stars and wonder how far away the objects are, where are they in relationship to each other, and how could I explain to a friend where you are looking in the sky?  If so, this lesson is perfect for you.  Again, you will be using FREE SOFTWARE from Harvard University to help you develop an understanding of galaxy around you.
         
    You are about to learn all about Galactic Navigation using the CHANDRA web site.  While you go through the tutorial, try to keep in mind the three things you have learned about how to navigate in any situation.  Come back here for a quick review quiz.  Click on the CHANDRA picture on the right to begin the tutorial.        


1)  What do we use as the origin for Galactic Navigation?

2)  Does our coordinate system use north/south/east/west?  What does it use?

3)  What is the unit length for Galactic Navigation?

4)  What are the similarities between navigating the Milk Way and navigating the earth?

5)  Can you explain why we see the bands of the Milky Way in the night sky?  Aren't we part of the galactic plane?
If everyone uses the same system to navigate our galaxy, then we have an understanding of how to define the location of celestial objects.  We can communicate with people in a language other than English.  We use the mathematical language.  Now that we understand how to navigate the galaxy, lets use CHANDRA to to find out where objects are in the sky.
