We are all travelers on a single current - a River of Space and Time flowing from the hearts of ancient suns into the distant future. But we aren't just standing on the banks watching it pass; we are part of the stream.

The Star River is an exploration of that profound connection. Hosted by Eric Loyd - the Astropotamus - this show bridges the gap between the technical and the transcendent. Through the lenses of astrophotographers, the melodies of musicians, and the insights of celestial explorers, we examine how we are inextricably linked to the cosmos.

Every journey begins with a ritual: sharing a drink to ground ourselves in the present before we wade into the infinite. Whether we are discussing the physics of light or the feeling of being under the stars in the desert, we seek to understand this current that moves through us all.

You are already in the River. Join us as we navigate its bends, its shallows, and its sudden falls. Raise a glass, find your place in the flow, and let’s see where the River takes us.

Explore the current at astropotamus.com/star-river or get involved - call 855-DEEP-SKY and share feedback, ask guest questions, or tell me where you are in the currents. I listen to every message & you might just find me on the other end!

  • AGNs and Ancient Messengers with Dr Saavik Ford
    Mar 24 2026

    From a wood stove in Brooklyn to AGN nurseries, Dr. Saavik Ford traces her journey down the Star River, inculding a stop at the Public Theater.

    What happens when you sit a world-class astrophysicist down with a glass of rare Italian wine and ask her to explain the messengers we use to navigate the universe? In this expansive conversation, I'm joined by Dr. Saavik Ford, a professor at CUNY and a researcher at the American Museum of Natural History, for a journey that meanders from the subways of New York to the edge of the observable universe.

    We begin with The Ritual, with a never-before-tasted vintage that traces Saavik's ancestral roots through a bottle of Nero di Troia before diving into the high-energy heart of Active Galactic Nuclei (AGN). She pulls back the curtain on the "glamour" of professional astronomy, revealing a world built on Python code, tedious data calibration, and the rare, breathtaking lore of being the last generation to ever put an actual human eyeball behind the lens of a world-class telescope.

    There is simply too much in this conversation to list here; you'll just have to listen to it. But we quickly move from the "canals" of Mars to the modern "Multi-Messenger" era. Saavik breaks down the five - and only five - ways we receive information from the stars, explaining how the recent discovery of gravitational waves has fundamentally changed our role as observers.

    Yet, for all the high-level science, this episode is deeply human. We discuss her personal mission of "lifting as we climb" through Astrocom NYC, a program she co-founded to help underrepresented students build a "scientist identity" and navigate the precarious path of academia. We even take a surprising detour into the world of professional theater!

    Whether you're counting photons from a quasar 14 billion light-years away or mentoring a freshman in a New York City classroom, we are all part of the same current. Saavik's story is a testament to the fact that science is not just a collection of data. It is a creative, collaborative, and deeply personal act of wonder that you won't want to miss.

  • Beyond the Dome: Backyard Imaging & Workflow with Greg Yancey
    Mar 17 2026

    Sometimes, the best way to travel through time is to sit still under the stars. I wade into the current today with fellow time traveler Greg Yancey for a deep dive into the backyard workflow. An award-winning backyard astrophotographer, he'll take us down the River and teach us about his transition from a permanent dome to a mobile APO setup. He shows us the unexpected ways astrophotography helps clear the mind, and we talk about what it means to truly connect with the night. In the world of astrophotography, the challenge is often found in the "unseen"; capturing light that has traveled for thousands of years only to be hidden by the glow of our own world. Greg has mastered the art of carving a path through that noise to reveal the stunning, intricate structures of the deep cosmos.

    From the iconic silhouettes of the Horsehead Nebula to the delicate filaments of the Question Mark, Greg's work is a masterclass in patience and technical grace. Learn about his journey from the shallows of the hobby into the deep waters of mono imaging, narrowband filters, and the relentless pursuit of detail. Greg shares his perspective on gear - including his ZWO and Askar setups - and how he maintains his sense of wonder while managing the complex math required to bring a nebula to life.

    You don't want to miss this one!

  • The Sound of the Void with Thomas Loupe
    Mar 10 2026

    On this episode of the Star River, I'm joined by Thomas Loupe, an artist who navigates the intersection of engineering, filmmaking, and music. Known for his atmospheric electronic project First Sun and his work on the the video game Natural Selection II (among others), Thomas has spent years "translating" the universe into sounds and visuals we can all understand.

    We discuss his Return Void project and the philosophy of making the cosmos accessible to everyone. As fellow travelers and musicians, we also dive into the "code" of creativity - comparing the math of synthesizers to the processing of an astrophoto.

    "What I love most about what I understand my connection to the cosmos and my connection to music to be is to take all of that together and combine it and make it so that other people in the world are able to have the experience that I wasn't able to have as a kid."


    Thomas and I definitely explore the deep parts of the River on this episode, and you're not going to want to miss it. Plus, an extra, super-duper, amazing surprise audio treat!
