Overview

Beloved science commentator Bob McDonald takes us on a tour of our galaxy, unraveling the mysteries of the universe and helping us navigate our place among the stars.



How big is our galaxy? Is there life on those distant planets? Are we really made of star dust? And where do stars even come from?



In An Earthling's Guide to Outer Space, we finally have the answers to all those questions and more. With clarity, wisdom, and a great deal of enthusiasm, McDonald explores the curiosities of the big blue planet we call home as well as our galactic neighbors-from Martian caves to storm clouds on Jupiter to the nebulae at the far end of the universe.

Read an Excerpt

Chapter 1: How Big Is Our Galaxy?

YOU TRY IT! Model Galaxy



WHAT YOU NEED

1. A large bowl
2. Water
3. Food coloring or milk

WHAT TO DO

1. Fill the bowl with water.
2. Using your finger, swirl the water around in a circle until it dips down a little in the center.
3. Let the water spin on its own for five seconds, then carefully pour just one or two drops of food coloring or milk in the center.
4. Watch the shape the food coloring or milk takes.
5. You have just made a model of the Milky Way!

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?
