Angela Brownlee is a science writer and editor specializing in space exploration, astrophysics, and the long, difficult road from idea to launchpad. She holds a master's degree in physics, where her research focused on stellar astrophysics, before trading the telescope for the keyboard. Over the past fifteen years, her articles and essays on exoplanets, deep-space propulsion, and the human future beyond Earth have appeared in popular science magazines, national newspapers, and digital publications across North America and Europe. She has also written and hosted a podcast series on spaceflight history, and she regularly speaks at science festivals, libraries, and school events — because she believes the next interstellar generation is currently in a classroom somewhere. *The Light-Year Frontier* is her first book. She lives in Vancouver, British Columbia, with her family and an unreasonable number of astronomy books, and she is at work on a second book about the search for life beyond the Solar System. She can be found online at angelabrownlee.com, where she writes about space science, publishes reading lists, and documents her own attempts to explain the universe in plain language.
