Pack your cosmic suitcase. This week on Planetary Radio, host Sarah Al-Ahmed is joined by Mark McCaughrean, astronomer, science communicator, and former Senior Advisor for Science & Exploration at the European Space Agency, to talk about his new book, “111 Places in Space That You Must Not Miss.” Part of the popular “111 Places” travel series, the book transforms the guidebook format into a tour across the Solar System and beyond, from Apollo landing sites on the Moon to Europa’s hidden oceans, and even the afterglow of the Big Bang.

Mark shares highlights from the book, stories from his career on missions like Hubble, Rosetta, and the James Webb Space Telescope, and reflections on how science and imagination come together to inspire exploration.

And in this week’s What’s Up, Planetary Society Chief Scientist Bruce Betts joins Sarah to talk about his brand-new children’s books, “The Size of Space” and “Are We Alone?,” part of our growing series with Lerner Publishing Group.
