One thing we have in common with the ancients is that all of the human race has gazed at the night sky, and the bright morning, and wondered, "What's out there?" Our universe is so vast and awe-inspiring that to learn about it is to learn about ourselves.

Learning about the universe is huge fun! In the almost infinite expanse above us, we can examine planets, galaxies, and phenomena so beautiful and complex that we never outgrow a childlike wonder. We see our own reflection in the moon, the stars, and in comet trails. The more we learn, the less we fear!
