About PBS Space Time
Space Time explores the outer reaches of space, the craziness of astrophysics, the possibilities of sci-fi, and anything else you can think of beyond Planet Earth with our astrophysicist host: Matthew O’Dowd. For all business inquiries and sponsorship opportunities please reach out to: pbsspacetime@lighthouseagents.com Matt O'Dowd spends his time studying the universe, especially really far-away things like quasars, super-massive black holes, and evolving galaxies. He uses telescopes in space to do it. Matt completed his Ph.D. at NASA's Space Telescope Science Institute, followed by work at the University of Melbourne and Columbia University. He's now a professor at the City University of New York's Lehman College and an Associate at the American Museum of Natural History's Hayden Planetarium. Previous host Gabe Perez-Giz is an astrophysicist who studies black hole physics. He received his Ph.D. from Columbia University and also hosted PBS Infinite Series.
How to read PBS Space Time's numbers
Average views per video (1,226,910). This spreads lifetime views across every public upload, so older uploads that have had years to accumulate views are averaged together with recent ones. It is a useful scale check, not a prediction of how the next video will perform.
Views per subscriber (156.2). A rough measure of how much watch demand each subscriber represents over the channel's lifetime. Channels that reach large non-subscribed audiences — through search, Shorts or recommendations — tend to show a higher figure than channels that rely mainly on their existing subscriber base.
Upload cadence (~3.2 per month). Averaged across the channel's full history of about 11.6 years, so a channel that changed format or publishing pace along the way will not match this figure in any single recent month.
All figures come from public YouTube channel data and are refreshed on a schedule. They are research signals for comparison and context — they are not private YouTube Studio analytics, and they do not include revenue, watch time or audience retention. Read the full methodology.
