There is a Sea of Interstellar Objects in the Galaxy with Amir Siraj of Harvard

Author: John Michael Godier May 23, 2026 Duration: 20:13

Oumuamua and Borisov were the first two interstellar objects found in our Solar system. And with the Vera C. Rubin Observatory about to become operational, it will improve our ability discover interstellar objects. Just how many interstellar objects are in our galaxy? How many interstellar objects in our solar system? Could some have landed and been preserved on the moon? Amir Siraj of Harvard joins John Michael Godlier on Event Horizon to discuss his work with Dr. Avi Loeb to continue the search and study of interstellar objects within our solar system.What is Planet Nine? with Harvard's Amir Siraj https://youtu.be/SwRmHrsNyFUImpacts of Dust Grains Accelerated by Supernovae on the Moonhttps://arxiv.org/abs/1908.08543Observable Signatures of the Ejection Speed of Interstellar Objects from their Birth Systemshttps://arxiv.org/abs/2010.02214Transfer of Life Between Earth and Venus with Planet-Grazing Asteroidshttps://arxiv.org/abs/2009.09512Want to support the channel?Patreon: https://www.patreon.com/EventHorizonShowFollow us at other places!Website: https://www.eventhorizonshow.com/@JMGEventHorizonMusic featured on Event Horizonhttps://stellardrone.bandcamp.com/https://migueljohnson.bandcamp.com/https://leerosevere.bandcamp.com/https://aeriumambient.bandcamp.com/FOOTAGE:NASAESA/HubbleESO - M.KornmesserESO - L.CalcadaESO - Jose Francisco Salgado (josefrancisco.org)NAOJUniversity of WarwickGoddard Visualization StudioLangley Research CenterPixabay


Curiosity about the cosmos often starts with a simple question, and that's where John Michael Godier's Event Horizon finds its rhythm. Hosted by author and futurist John Michael Godier, this podcast delves into the profound and the perplexing at the edges of our understanding. Each episode builds a narrative, weaving together discussions on astronomy, astrophysics, and the latest space science news with broader themes of technology, history, and futurism. The conversations are grounded by special guests who bring expertise and diverse perspectives, turning complex ideas into engaging explorations. You'll find the dialogue moves from the concrete details of scientific discovery to the speculative implications for our future, all with a thoughtful and accessible tone. This isn't just a recap of headlines; it's a deep dive into the context and consequences of what we're learning about the universe. For anyone who looks up at the night sky and wonders about black holes, the potential for life elsewhere, or where our technology might take us next, this podcast offers a compelling space to linger on those big ideas. The production emphasizes clarity and depth, making even the most daunting topics feel within reach. Tune in for a regular journey to the frontiers of science and human thought.
