Cosmic Survey: What are your ideas about the Universe?

Question 1: How big?

You have been provided with images of seven different objects in space. Try arranging the pictures side by side in a row, in order of actual size of the object (or field of objects) pictured. Order the objects so that the smallest is on the left, largest on the right. Write down and keep track of questions that arise as you order the images.

When you are satisfied that you have the best order, record the names of the objects in the spaces below.


1. 2. 3. 4. 5. 6. 7.
