Phil Plait:

We walk past wonders in the sky all the time, ignoring them. The Sun, a million miles wide, performing stellar alchemy in its core. The Moon, battered and airless, a 4-billion-year history laid out for all to see. Saturn, a billion miles away, ringed and gaseous and attended by dozens of icy moons, a jewel of the solar system. Countless stars scattered across the Universe.

If all that can be just over your head without you even knowing, what are you missing right here on Earth? What things, what people, are right in front of you as you pass them by? The Universe is wondrous and spectacular, but very, very remote. The Earth and the people on it are right here, within our reach.
