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.

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.

They say that even the brightest star won't shine forever. But in fact, the brightest star would live the shortest amount of time. Feel free to extract whatever life lesson you want from that.

Not everything that’s cool is science, but everything in science is cool.
