Do our best ideas truly come from the pub? Dr. Alfredo Carpineti - astrophysicist, IFLScience writer, and chair of Pride in STEM - certainly thinks so. Alfredo bridges the lab and the lounge to find the "invisible rainbows" that connect us all to the cosmos.

In this journey down the River, we explore the "Astroholic" spirit: the belief that if the universe can forge complex spirits in interstellar clouds, we can certainly uncover its secrets over a shared glass.

In this episode, we navigate:

  • The Invisible Rainbow: A deep dive into Spectroscopy and the electromagnetic spectrum; how astronomers use "hidden" light to see the unseeable.
  • Pride in STEM: The vital importance of queer visibility in the sciences and Alfredo’s mission to ensure that the wonders of the universe aren't locked behind a laboratory door.
  • From Mixology to Modern Science: How Alfredo’s background as a mixologist fuels his philosophy that science communication never stops, and that science is, above all, a human right.
  • The Ritual: Tracing the evolution of stars while grounding ourselves in the present moment.


Whether you’re a space enthusiast, a wine lover, or a seeker of a more soulful connection to the infinite, this conversation will change the way you look at the night sky.

Bleep! with Ana Navarro

Bleep! with Ana Navarro

Fear thrives in silence and confusion. Ana Navarro rejects both. Her voice is an antidote to today’s chaos. Her new podcast, Bleep! with Ana Navarro, takes on today’s most pressing issues with the voices most connected to it: decision-makers, political leaders, cultural shapers, and people on the frontlines of the story. The conversations acknowledge the emotions we all feel—despair, sadness, fear— but emerge with knowledge, perspective, and hope. The belief is simple: fearless dialogue can transform fear into courage, and courage into change. When fear dominates the headlines, this show digs deeper. Because information, debate, and conversation don’t just ease fear, they give us power to shape the future.
