Mark Zastrow

Mark got his bachelor’s degree in astrophysics from the University of Minnesota and master’s degrees in astronomy and science journalism from Boston University. At BU, he researched topics ranging from Jupiter’s magnetosphere and Enceladus’ plume to stellar activity on M dwarfs and the migration of hot Jupiters. Before joining Astronomy, he freelanced in Seoul, where he covered stories including AlphaGo’s victory, air pollution, dog cloning, research misconduct, and the MERS and COVID-19 outbreaks. He was also the science contributor for tbs eFM’s This Morning, the flagship news program on Korea’s largest English-language radio station, and editor of a South Korean politics newsletter from Korea Exposé. Mark lives in Milwaukee with his fiancé, Katelyn, and their two Jindo mixes, Gguri and Ahto. Mark is a licensed pilot, though these days, you’ll find him in his free time hiked out on his Laser sailboat on Lake Michigan or on the hill between turns 5 and 6 at Road America cheering on his beloved Indy cars.
