Phil Plait is an astronomer, author, and science advocate. His blog, Bad Astronomy, is hosted by Discover Magazine, and he writes about news and current issues facing science. A common topic is astronomical doomsday: ways mythical and real the world can end. He's fascinated by asteroid and comet impacts, and is a big supporter of finding, tracking, and ultimately deflecting any dangerous rocks heading our way.
