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. patreon.com/pbsspacetime","last_synced_at":"2026-07-24T02:17:15.545680+00:00","page_url":"https://stenobird.com/podcast/pbs-space-time-7778773"},"episode":{"title":"Do Neutron Stars Gleam Within Dark Matter?","slug":"do-neutron-stars-gleam-within-dark-matter","published_at":"2026-07-14T11:30:00+00:00","page_url":"https://stenobird.com/podcast/pbs-space-time-7778773/do-neutron-stars-gleam-within-dark-matter","show_page_url":"https://stenobird.com/podcast/pbs-space-time-7778773","url":"https://traffic.megaphone.fm/VG5072614331.mp3?updated=1778670625","audio_url":"https://traffic.megaphone.fm/VG5072614331.mp3?updated=1778670625","summary":"👉 Head to https://brilliant.org/spacetime/ for a 30-day free trial + 20% off your annual subscription Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetime Neutron stars aren't dark matter--we figured that out a while ago. But new research is telling us that they may be dark matter factories. They may produce the exotic axion, one of the most popular dark matter candidates.
