"Our Milky Way galaxy gleams with more than 100 billion stars, and millions of those are likely to possess planetary systems of their own." (National Geographic)

The text is intentionally faint (as though written by starlight!) to reflect how little we still know, and how much we still need to learn in order to get our species up and out into the stars.
