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
