I found myself surrounded by people who celebrated intellectualism and engagement, and who thought that my ironic oh-so-cool disengagement wasn’t clever, or funny. It was a simple and unspectacular response to very complicated and compelling problems. And so I started to learn, because learning was cool. - John Green

Venus is a gorgeous naked-eye planet, hanging like a diamond in the twilight -- but its beauty is best looked at from afar. Even though Mercury is closer to the sun, Venus is the hottest planet in the solar system, due to a runaway greenhouse effect, and has the most volcanic activity in the solar system. Its north and south poles were flipped, causing it to rotate backward and making for very strange days on this beautiful but inhospitable world.
