Other job markets may lay claim to the title, but astronomy is actually the world's oldest profession.

You can experience the thrill of discovery, the incredible, visceral feeling of doing something no one has ever done before, see things no one has ever seen before, know something no one has ever known before. ... Welcome to science, you're gonna like it here.

It's amazing to me that not only can we put a probe around Saturn and get images of its moons, but our math and physics are so freaking accurate we can say, "Hey, you know what? On this date at this time if we turn Cassini that way we'll see a moon over 2 million kilometers away pass in front of another one nearly 3 million kilometers away." Every morning, I have a 50/50 chance of finding my keys. That kinda puts things in perspective.

Our solar system is fantastically bizarre. There are worlds with features we never imagined. Storms larger than planets, moons with under-surface oceans, lakes of methane, worldlets that swap places...and that's just at Saturn.

If you took every nuclear weapon ever built at the height of the Cold War, lumped them together and blew them up at the same time, that would be one one-millionth of the energy released at that moment.

However, science isn't just about showing when you're right; it's also about showing when you're wrong.

Sixty-five million years ago the dinosaurs had a bad day.
