I'm a journalist specializing in astronomy and physics stories. My work has appeared in The New Yorker, National Geographic, The New York Times, The Wall Street Journal, The Christian Science Monitor, Quanta Magazine, Wired, Scientific American, Nature, Science, PNAS, Live Science, and many other places. In my spare time, I'm writing a science-fiction novel about the difficulty of knowing things, and also aliens.
