Excerpt
Chapter 1: How Big Is Our Galaxy?
YOU TRY IT! Model Galaxy
WHAT YOU NEED
WHAT TO DO
The food coloring or milk should take on a spiral shape, with long arms wrapped around the center of the bowl. That is the shape of our Milky Way Galaxy. The sun and billions of other stars all swarm around a central bulge. Galaxies come in many different shapes, but the spirals, like ours, are the most beautiful. Don’t you agree?
