SpaceTime with Stuart Gary

Stuart Gary spent 19 years covering science on Australian public radio before launching SpaceTime as a podcast, and that broadcast experience shows. Each weekly episode packs multiple astronomy and space news stories into a tight, well-produced package. With over 1,200 episodes, SpaceTime has one of the deepest back catalogs in the space podcast world. Stuart brings in recurring contributors including Alex Zaharov-Reutt for tech segments and Tim Mendham from Australian Skeptics, plus rotating academics from universities like Sydney and Colorado Boulder. The show has a 4.2 rating from 297 reviews—the lower score seems partly tied to listener opinions about commercial breaks and Stuart’s distinctive delivery style, which you will either find authoritative or a bit much. A premium tier is available at five dollars a month for those who want ad-free episodes. The Australian perspective gives the show an angle you will not find in most American-dominated space media, with more coverage of Southern Hemisphere observatories and international space programs. Episodes cover a broad spectrum from gravitational wave discoveries to satellite policy, and the journalistic approach means stories are sourced and fact-checked rather than speculative. Solid choice for listeners who want hard news delivered efficiently.
