What are red giants and white dwarfs? How is a pulsar different from a quasar? What was the Big Bang, and when did it happen? Does the Universe have a center, and if so where is it? Are dark matter and dark energy related? Some of the oldest—and literally, biggest—questions of all time are now known to astronomers, but whenever we answer one we open the door to a dozen more. We will explore those questions and the very latest in answers.
