For the next 12 or so Sundays, join me on Twitter (@ShareefJackson) as I livetweet the show Cosmos. The most recent episode "When Knowledge Conquered Fear", deals mostly with comets. Ancient civilizations saw comets as messages from God of impending doom. It took scientists like Robert Hooke, Edmond Halley, and Isaac Newton to prove that comets were a part of the solar system whose travel patterns can be predicted with startling accuracy.

Knowledge is power, and also inspires great music. Check out Eric B and Rakim's "Know the Ledge" off of the soundtrack to the movie Juice. After that, check out the Storify of my tweets below!
